Slime, It was one of the most popular trends in 2017, It’s somewhat a trend now. What's so astonishing about slime? Well in my opinion i say that it's a stress reliever, fun to play with, the texture, noises that it makes, and the satisfaction of it. Slime can be fun to play with but can hurt you. What exactly is the definition of slime? According to the dictionary it says it’s “a moist, soft, and slippery substance.” I will be talking about the chemistry of slime. How did slime start to be a trend? Well visitors from Discovery Center were invited to become chemist by making their own slime. They all begin to add two chemical solution and mixing it together. They then made an outcome that was “slime-y.” They shared it with everyone and …show more content…
Seeing that the borax and glue are mixed first with or without water, when combing then, they cooperate through hydrogen bonding. Matrix polymer is the glu and the borax combined together to make the slime, rather than linear polymer, which is glue by itself (Discovery center). What makes slime stretchy and thick? The glue has flexible molecules in it called polymers, they slide past each other as liquid. Borate ion (B(OH)4- is borax in water forming the ion. When the solution (borax) is added to the glue, the borate ion help connect the polymer molecules to each other so they won't be able to move and flow as easily. When enough polymer molecules gets absorbed together correctly, the glue changes for liquidity to a really satisfying rubbery thing called slime. You can also add water to it, which would make glossy slime. Water would help the polymer molecules slide past each other so the slime would be able to flow. It could become a piece of slime if you let the water evaporate (ACS Chemistry for …show more content…
Yes, it makes the slime stretchy which it lets it to make it bounce. When alcohol and borax are attracted to each other they go through chemical reaction. Accordingly the chemical reaction absorbs heat energy also known as endothermic reaction (The national science and technology centre). As i mentioned earlier about that ‘borax can be dangerous by giving you a 3rd degree burn’ i will now be talking about ‘Why can making homemade slime be bad for you?’. I know playing with slime can be fun, but there can be consequences. Getting a first, second, or even a 3rd degree burn! How does borax or sodium borate burn the skin? Well borax is sold as a cleaning product also it’s a mineral. It rarely causes chemical burn because borax is a mild irritant. There are three stages of a burn. First, “there’s the length of time that a person is in contact with the chemical or source of heat. Second, there’s the strength of chemical or heat, Finally, the thickness of the skin also plays a role and children have thinner skin.” said Copper. A chemical happens when a chemical damages the skin, you can stop the damage by washing of the chemical, otherwise it will keep causing damage. There are first-, second-, and third-degree burn. The first-degree burn, which is when the burn only damages the top layer of your skin, This degree burn will make your skin turn red, nothing else. Second-degree burn is a lot more dangerous, this happens when the damage spreads
Hydration of alkenes is characterized by the addition of water and an acid-catalyst to a carbon-carbon bond leading to an alcohol. Dehydration is exactly the opposite in which dehydration of an alcohol requires water to be removed from the reactant. Equilibrium is established between the two processes when the rate of the forward reaction equals the rate of the reverse reaction. The alkene that is used in this experiment is norbornene. Through hydration of norbornene, an alcohol group should be present on the final product yielded what is known as exo-norborneol. Percent yield is a numerical indication of how much of the reactant was actually reacted to yield product. The equation for percent yield is shown below:
Glow sticks get their “glow” when two chemicals are mixed together because of a chemical reaction. The chemical reaction is called Chemiluminescence. A Typical glow stick has a plastic tube with a smaller inner tube inside. There are three components, two chemicals and a fluorescent dye which accepts the energy and helps covert to light. There is more than one way to make a glow stick, but the most common uses a solution of hydrogen peroxide and phenyl oxalate ester along with the fluorescent dye. The hydrogen peroxide is in its own compartment away from the other two components until ready to use. The fluorescent dye is what determines the subsequent color of the glow stick when the chemical solutions are combined.
Have you ever wondered who invented bubble gum, or why it’s pink? How do you go about getting the answers to these questions? Easy. Think way, way back, not to prehistoric times but close, 1928.
Lean Fine Textured Beef (LFTB); or its more common name in recent years, Pink Slime is becoming quite the hot topic. Questions are raised on whether the pink slime is safe for human consumption. The name alone has given it a pretty negative reputation. On top of whether or not pink slime is safe or not, another concern is what benefits, if any does it offer as opposed to other meat alternatives. Not different than any other story this one has two sides; although there are a lot of allegations that pink slime is not safe for human consumption and it does not offer any benefits, there are many responses putting the allegations to rest. What if it wasn’t called pink slime?
Stiffness The effect that this additive has on the polymer in terms of stiffness is that the fillers are very useful because it makes the polymers very strong and stiff. This makes it hard to break.
The reason why the gummy bear expanded and swelled in water is because of diffusion and going through osmosis. The molecules did diffusion by going from high concentration (the water) to the low concentration (the gummy bear). The diffusion of the water molecules went through a selectively permeable membrane to perform osmosis. By performing diffusion and osmosis, the molecules were at an equilibrium, which is when the concentration of molecules are equal on either side of the selectively permeable membrane. Although the membrane lets certain molecules through, some larger molecules cannot pass which is how basic living things perform life processes such as transporting water in a
They are held together with a liquid binding solution, such as gum tragacanth, gum arabic, or methylcellulose. From this mass a stiff paste is formed, which is then cut into sticks and allowed to harden. Even though these sticks look similar to chalk, they are not be confused with each other, since colored chalks are nothing more than a limestone impregnated with dyes.
The product was made from 4-methylcyclohexanol. The chemical, 4-methylcyclohexanol is used in industrial settings. In 2014, West Virginia was exposed to this chemical in drinking water. Since this chemical is used to wash coal of its impurities, it was unsafe to drink the water as well as take a shower (CNN). Similarly, 4-methylcyclohexanol has a strong smell which may cause people to have symptoms like vomiting, skin irritation, and trouble breathing. Diesel is also replaced by 4-methylcyclohexanol (National Geographic).
Slime is a special play material made up of tangled polymer. It is mostly made by mixing polyvinyl with the chemical compound known as borate ions, you can describe it as a liquid and mix it in a sizable container for mixing. In a more difficult explanation, slime is more commonly known amongst scientists as a Non-Newtonian fluid. These are thick liquids that have a numerous selection of viscosity.
The ingredients used in making slime contain fundamental additives that, when mixed together, cause the thick, gooey, slime every kid enjoys. Polymers are made from several smaller molecules joined by chemical bonds. The polyvinyl allows the mixture to feel slimy. Combing the polyvinyl and Borax together creates a chemical reaction. The mixture becomes cold, thicker, and elastic. This combination mixed together produces slime that is fun and safe for all ages.
chains instead of hydrogen atoms. Cross-linking is another way in which the polymer can be made stronger. This involves ultraviolet radiation that bombards the polymer with electrons and formulates bonds between the molecular chains of the polymers. This is like linear polyethylene but different in that it is more impact resistant, and it has a much higher density. This allows it to be stored or be used with different chemicals that would normally cause the polymer to desolve.3 This can start to become a problem because as the polymer continues to become chemically enhanced. So the ways of dissolving and recycling the polymer become more difficult.
This is an example of a soap molecule. The hydrocarbon end is non polar and hydrophilic (water hating) and the carboxylate end is polar and hydrophilic (water loving). This the property which allows it to clean, it acts as an emulsifying agent. The soap disperses in water to form miscelles where a negatively charged surface is formed and hydrocarbon chains are in the centre. These miscelles surround droplets of dirt or grease suspending them in the water so they can be washed away.
Dip the brush into the liquid to get a little quantity, which is enough for one nail. Then dip this brush into the acrylic powder. A small moist ball would be formed at the brush end. Apply this to the nail.
Gummy Bears are mostly made of gelatin and sugar. Gelatin is a permeable substance which means it allows liquids to pass through it. A sponge is a good example of a permeable object. It allows liquid to pass through it and expands as liquid is trapped inside. A solid object, like a rock, is not permeable and will not allow water to pass through it. If you place a rock in a cup of water no water will pass through the rock making it expand. The rock will be the same size when removed from the water as it was when placed
This invention was the blender. This was a big success not only in American homes, but also in restaurants and soda fountains. With this invention the milkshake became even easier to create. This meant that milkshakes could be made faster, which in turn meant more people would buy them because they could get them quickly. The blender not only cut down the preparation time of the milkshake, but it also meant that other stores would try to create milkshakes rather than just Walgreens. As more inventions were introduced to society, the more milkshakes were
