Hydrogen Bond Chemistry Definition

Hydrogen Bond Chemistry DefinitionHydrogen bond chemistry is the study of molecular bonds and their connection to chemical reactions. It is closely related to crystallographic modeling and chemical kinetics. The definition of hydrogen bonding in the molecular field is that the molecules are interconnected to each other through bonds and here that connection will form or break depending on the weight of the molecules. Each molecule contains four bonds.Hydrogen bonding can be explained using concepts from polymers, polyelectrolytes, and organic chemistry. For each single molecule of a polymeric material, it has two components, such as the positively charged proton, and the negatively charged electron. Then, it will have many covalent bonds between these two components. The chemical properties of these two components are dependent on the type of polymer in which they are formed. Therefore, all polymers will have the same general properties, unless they were designed specifically for dif ferent materials.Polymers have several properties. They can be tensile elastic, elastic modulus, shear modulus, tensile strength, and chemical resistance. All of these properties can be found in polymeric materials.The general properties of polymers include; elasticity, permeability, conformability, compressibility, adhesion, ductility, tensile strength, shear, and shear modulus. Each property has a specific purpose in manufacturing, but we will look at only one. The properties of the elasticity of the material depend on the elastic modulus. It is used to find the strength of a material to resist stretching and deformation. It is also used to find the tensile strength of a material.Permeability is used to describe the material's ability to allow the passage of liquids and gases. The greater the permeability of a material, the easier it is for liquids and gases to pass through it. In other words, a material with higher permeability is more pliable. The lower the permeability, the mor e rigid and tough a material is. Thus, there are materials with high permeability, but many high resistance values.The chemical resistance and deformability of the material are defined by two variables. Chemical resistance refers to the property of resisting change in direction under stress. Deformability describes the property of being able to retain its shape under stress. It may be considered the most common property of most materials. This allows the material to be molded and extruded into different shapes without losing shape or forming holes.The type of cross-sectional area in a polymeric material is dependent on the chemical properties of the specific polymeric material. Other variables in cross sectional area include; the volume fraction, the shear fraction, the area fraction, and the junction fraction.Hydrogen bond chemistry also describes the bond that forms between two positively charged molecules. It defines the bond, in which a positively charged molecule becomes attach ed to a negatively charged molecule. The interactions between positively charged molecules and negatively charged molecules will form and break bonds. Therefore, a chemical reaction will take place depending on the rate of change in bonds. The rate of change will depend on the charge imbalance and the bond length, among other factors.

How to Survive N00bdom in League of Legends

How to Survive N00bdom in League of Legends League of Legends is quite the challenging game, but as with all things, it just takes time. Photo by marckvision on Flickr. League of Legends is an immensely popular free-to-play combat strategy game with 32 million monthly active players. As a PC gamer, its almost impossible to avoid LoL, as its usually called, but I didnt want to become hooked on a game that takes about 45 minutes per match during the school year, so I started learning to play LoL just a week ago. And thats when I discovered how very unfriendly the League of Legends community can be. stop feeding the enemy u ****ing n00b, why are you even playing, and (my username) so good, wtf go die are all milder comments that Ive received while playing. Needless to say, its not easy being a n00b in the LoL community. Here are some tips on how to survive n00bdom which Ive learned after a week or so of intense playing and improvement from n00b to a somewhat not horrible player. 1. Do your homework The internet is your best friend! Before you start playing, do a bit of reading and learn about how the game is played because the in-game tutorial is horrible. I suggest this guide which has a bunch of terms and basic ideas that you want to know. When you know what champion (character) youd like to play, find build guides written by pro players usually with strategies on how to best win a game with your character. Watch livestreams or Youtube videos of pro players or spectate some games from the LoL client itself and take some tips. League of Legends is a difficult game to understand, so a bit of homework goes a long way. (Yes, I know its summer, but its for a purpose!) A Tryndamere cosplayer at Pax Prime 2012. Photo by getdarwin on Flickr. 2. Play with a friend if possible If you can, grab a buddy who knows how to play LoL. They can give you friendly pointers on what to improve and show you the ropes. Most importantly, if other players start verbally harassing you, they will stand up for you. A lot of the negativity in the LoL community is because players dont stick up for each other. If a friend says, theyre new, give them a break or we all have bad days, it happens, players are much more likely to back off than if you try to defend yourself. Also the game is just a lot more fun with friends! 3. Play a lot of bot games Bot games or games against computer controlled champions are a great way to practice your skills. Theyre very low-key because most players play bot games for stress relief and practice, so theres not much pressure should you mess up. Playing bots is a great way to get accustomed to gameplay and to get used to a champion. PvP (player vs. player) games are much more stressful and players tend to get more riled up during them; they also require a lot more skill because humans are unpredictable. Id recommend not playing PvP until you have a grasp on basics such as last-hitting and general roles. 4. Tell people you are new LoL takes a lot of practice and patience. Photo by DrabikPany on Flickr. Dont be afraid to admit that you are new. Yes, some jerks will make fun of you, but most players are understanding if you let them know that you might need some help. A simple, Hey all, Im new so Im not very good at this game, but Ill try my best will let your teammates know that youll need extra protection and will let them know why you will be dying a lot. Otherwise, some players may try to report you for feeding, or letting the other team kill you so they win. If youve made an honest effort to show that you are new at the game and trying your best, thats usually well-appreciated. 5. Ignore Lets say a player wont stop harassing you about how youre such a n00b. The ignore button works wonders. Learn it. Love it. It will mute your teammate/enemy/frenemy(?) and youll no longer be able to see their spew of hate. I try to be cautious with this because the chat is very integral, but if they have nothing better to say than verbal abuse then anything they have to say about actual gameplay has no worth to me. 6. Report toxic players Make sure in the post-game stage to report verbal abuse or negative attitude. Always use the additional comments box to detail how they were a toxic player. This goes to the Tribunal, who review cases and try to make LoL a better community! Its okay to be a n00b, but it does attract a lot of negative attention and it does make it difficult to get better. But with time and a lot of practice, you too can safely escape the realm of n00bdom! Do you have your own tips? Let us know in the comments.

Tutor Time Livingston - How to Choose the Right Tutor Time Livingston

Tutor Time Livingston - How to Choose the Right Tutor Time LivingstonTutors come in all shapes and sizes, are they in person or online. At times, it may be difficult to choose a tutor time Livingston from the many offers that are available. It can be confusing and frustrating as a parent to choose the perfect tutor that can help your child learn the necessary skills. Here are some tips that can help you make an informed decision.One of the biggest differences between online tutors and face-to-face tutors is that a face-to-face tutor provides support directly to the student. This makes the tutoring experience a much more hands-on one. You have a face-to-face tutor that you can talk to while your child is receiving feedback. With an online tutor, you may not get that much control over the tutor's guidance and feedback.The second reason that it is important to make sure you compare multiple tutors before making a decision is because you want to be able to compare their tuition fees. Tui tion fees vary greatly depending on whether you are tutoring at home or at a local school. If you opt for a local school, this will be even more important because you will be paying the difference in tuition fees. For the same tutoring services, you will find it a bit more expensive for an online tutor versus a face-to-face tutor.In addition to comparison of tuition fees, consider the age group of the online tutors you are considering. The younger a student is, the less experience he or she will have with tutoring and might not be up to par for your child. Consider the tutor's level of experience and feedback that he or she has received in previous tutoring sessions.Another factor to consider is whether the online tutors that you are considering have worked with similar students in the past. Even if they seem to have plenty of experience, does this mean that they can provide tutoring that they have received in the past? Look for people who have been in your child's or teenager's cla ss for a long time. A lifetime of experience will be a big plus for your child.Do not forget to talk to the tutor about any additional fees for the tutoring session. It is true that tutoring services do charge a fee, but you should be sure that you are being charged only for the tutoring session. Most online tutors will also charge for extra materials that they give to your child. These extra charges should not be considered as part of the service fees. Make sure that you understand all fees in writing.If you have made it this far and you still feel overwhelmed by the selection of tutors that are available to you, then you may want to consider hiring a tutor to help your child. This way, you will not be forced to make a choice. Try online tutoring and find the right tutor to help your child develop a passion for learning.

LewisYou’d be surprised at just how much tea is consumed in Japan.4.1 million tonnes of tea are produced yearly and China is the main producer. The Japanese tend to consume everything they make. Only 3% of their production is exported. There are dozens of Japanese tea varieties with the main differences occurring during manufacturing and how they’re consumed.Let’s have a look at the different types of tea in Japan.

Leaves are steamed for a minute to stop them oxidising during the drying process. It’s hard to come by outside of Japan and most sencha produced is consumed in Japan. If you find tea growing in Japan, it'll probably be sencha. (Source: Pharaoh_EZYPT)It’s green and has a slightly bitter taste. It needs to be infused at 80 ºC minimum. If you want a stronger taste, you can increase the temperature. It only takes between a minute and 90 seconds to infuse.There are different levels of quality and the first harvest tends to be of the highest quality and most sought after. This is known as sencha.Did you know that green tea is a non-oxidised tea?Learn more about attending a Japanese tea ceremony.Bancha: Japan’s Second TeaBancha is a lower-quality tea whose production is very similar to that of sencha. Bancha is from tougher leaves which are usually harvested from the second flush. As a result, it’s cheaper than sencha. Bancha tea is considered to be of a lower quality than sencha. (Source: xegxef)There are several different types of bancha:Hakuta bancha and kyobancha: The leaves are steamed and then sun-dried. This results in large brown leaves.Kageboshi bancha: The entire plant is harvested and then hung out to dry in the shade.Kancha: This is the bancha harvested in winter.Hojicha: The Cheapest Japanese TeaInvented in Kyoto in the 1920s, this is a green tea that comes from bancha, sencha, or kukicha. It’s roasted at 200 ºC before being rapidly cooled. Its leaves take on a red colour and it has caramel flavours.It barely contains any caffeine and can even be given to children despite its strong taste. It’s served in Japanese restaurants and aids digestion.Did you know that differences in tea comes from the manufacturing process and harvest not the plant?Discover what happens in a Japanese tea ceremony.Gyokuro: Japanese Luxury TeaThe gyokuro, literally “jade dew”, is one of the most luxurio us teas in Japan. 20 days before the harvest, the plants (usually yabukita) are put into the shade under a komo to protect them from the sun. The chlorophyll and flavours concentrate in the softest leaves. Afterwards, the process is the same for sencha and bancha tea. The leaves are steamed and then dried. The leaves are then rolled into small pine-coloured needles.The result is a tea that’s less bitter as there’s less catechin. This production method originated 2 centuries ago in the Uji region while nowadays, gyokuro is cultivated near Kyoto, Nagoya, Okabe, and Yame.The tea can be infused at a lower temperate (50-55 ºC) for two minutes maximum or 60 ºC for a minute. It has a very pronounced taste and contains a lot of caffeine. Drink it slowly on account of how strong the taste is.

The leaves for this tea often come from gyokuro. The unrolled tencha is turned into a powder using a machine that takes up to an hour to make just 50g of matcha. Matcha is the tea used in Japanese tea ceremonies. (Source: naturalogy)Matcha originates in China where the tea was used as a medicine once turned into a powder.  Nowadays, it’s often used in Japanese tea ceremonies (Chanoyu). You don’t need to infuse matcha as you can just pour 85 ºC water over it and whisk it for 30 seconds to create a foam. Matcha is also used in baking.Learn about the history of the Japanese tea ceremony.Genmaicha: A Mix of Tea and Roast Popped RiceGenmaicha is often served in restaurants. This is sencha, bancha, or even gyokuro that’s mixed with puffed rice. In some cases, matcha will be added to create an even more original blend.  There’s a very particular taste and the flavours from the tea mix with the flavours from the rice to create notes of dried and roasted fruit. It’s brewed in water at 80-85 ºC for between 3-5 minutes.Tamaryokucha: Fruity Japanese TeaOther types of green tea use the ancient Chinese method of steaming the leaves just after har vest. Tamaryokucha uses the current Chinese method of drying the leaves out.  The result is a fruity and flowery flavour which is unlike the usual flavours you find in Japanese teas.Other Types of Japanese TeaTea lovers will have a great time in Japan! There are so many varieties of tea that you could spend your entire trip trying them. Forget about flavoured teas like Earl Grey and Darjeeling and enjoy Japanese flavours tea:Aracha: The term means “unrefined”. The production process is the same but omits the sorting process. This tea is sold in bulk where a third party will often charge to sort or process it. Several teas can be made from these leaves.Fukamushicha: This is more a production method than a type of tea. All teas can be fukamushi. The leaves spend between 1 and 2 minutes being steamed. The result is a brittle tea that can dissolve in water.Funmatsucha: This is a process that’s similar to matcha but at a much lower quality.Kabusecha: Much like gyokuro, the leaves a re covered before harvest but only for between 10 and 15 days. The result is a tea that’s halfway between the flavour of gyokuro and sencha. It’s quite a rare variety that only accounts for 4% of Japanese production.Kamairicha: Here the leaves aren’t steamed but rather cooked at 45 ºC.Kocha: From black tea, the leaves are oxidised a lot.Konacha: This is made from the dust after processing gyokuro and sencha. It’s a strong-flavoured tea powder.Kukicha: This is a tea made from stems, stalks, and twigs. It’s refreshing with a nutty and creamy sweet flavour.Mecha: This is made from the early leaf buds.Sanpincha: This is a jasmine tea that’s consumed a lot in Okinawa. Japan has many different types of tea. (Source: chezbeate)The Japanese are also fans of oolong tea that’s harvested in Taiwan and China. It’s a lightly oxidised tea that’s been steamed. Similarly, you can also find pu’er tea which is an affordable dark tea from China.So which Japanese tea will you try?If you'd like to learn the language before you go to Japan or a Japanese tea ceremony, you should get in touch with one of the many talented and experienced private Japanese tutors on Superprof. With three main types of private tutorial available, face-to-face tutorials, online tutorials, and group tutorials, there's a solution for every type of learner and budget.Group tutorials are great for those on a budget as the cost of the tutor's time is shared amongst all the students in attendance. While you won't get as much one-on-one time with your tutor in these tutorials, if you and a group of friends are going to Japan and would all like to learn a bit of the language, they're a great option.Face-to-face tutorials tend to be the most effective tutorials because they're tailored to an individual student who'll have the tutor's undivided attention throughout the session. However, with all the extra work the tutor will put into tailoring their tutorials, you can expect to pay more and these types of tutorials are usually the most expensive.Online tutorials are similar to face-to-face tutorials but your tutor won't be in the room with you. Thanks to the internet, you can get Japanese tutorials via webcam. Your tutor might even be in Japan!Before you decide upon your tutor, remember that many of the tutors on Superprof offer free tuition for the first hour. Try a few of them out and see who you get along with, who offers the best tuition, and ask them about their teaching approach, rates, and what you'd like to learn.Personally, when you first start learning a language, you might want to start with the cheaper option of group tutorials and move onto online or fa ce-to-face tutorials once you start to get a better idea of what you want to learn. However, at the end of the day, the choice is yours.

Online Undefined Slope Tutors

Online Undefined Slope Tutors On an X-Y coordinate plane, when the points are written in the coordinate form of (x, y), then the slope of the line joining any two points can be found out since the slope of a line is the change in the y-coordinates to the change in the x-coordinates. This definition of slope is also popularly known as rise over run. Now, if change in the x-coordinates is 0, then we get an undefined slope since the denominator goes to 0. Example 1: Calculate the slope of the line joining the points (3, 5) and (3, 9) in the X-Y coordinate plane. Given two points: (3, 5) and (3, 9). Slope of a line joining the two points (x1, y1) and (x2, y2) is given as: Slope, m = (y2 y1)/ (x2 x1) This gives: m = (9 5)/ (3 3) == m = 4/0 Now we get, 0in the denominator and anything divided by 0 is infinity. Therefore we get an undefined slope and the line is a vertical line of equation x = 3. Example 2: Calculate the slope of the line joining the points (-2, 4) and (-2, 7) in the X-Y coordinate plane. Given two points: (-2, 4) and (-2, 7). Slope of a line joining the two points (x1, y1) and (x2, y2) is given as: Slope, m = (y2 y1)/ (x2 x1) This gives: m = (7 - 4)/ (-2 (-2)) == m = 3/0 Now we get, 0 in the denominator and anything divided by 0 is infinity. Therefore the line has an undefined slope and the graph is a vertical line of equation x = -2.
