Macromolecule test 1 differs from the second chart by testing non-reducing sugars in the first test and proteins in the second. In depth the lab required to heat the sample at times, mix them, and add them to a warm water bath of 100 Celsius. The following graphs were obtained by following the guidelines within the
It can be hypothesized that the water in the product affected the melting point
The data table provided below obtained melting point data for crude product, pure product, and mixture of the pure and 4-tert-butylbenzyl. 12. The TLC data obtained is provided in a table below. The TLC data was conducted solely in a 9:1 hexane/ethyl acetate solvent solution as opposed to the 1:1 and pure hexane solution as well. This was due to the lack of time, but as explained in number 7, a very polar solvent (1:1 solution) or non-polar solvent (pure hexane) is not ideal when obtaining
These results a somewhat inaccurate due to the fact that when the solutions were actually freezing is difficult to tell. Some solutions froze slowly and showed a plateau, while others
One property of nonelectrolytes is that they tend to dissociate. So, when they dissociate, they produce an even greater freezing point depression. If it produces a greater freezing point, then it will not help the ice on the road melt. 101) Sodium- Sodium controls the total amount of water in the body; essential to humans.
Also the MAG formation was in between 35-52% and FA formation was less as compared to DAG giving ratios same as obtained during glycerolysis reaction. There can be two possibilities, one may be that at high glycerol concentration more amount of water is required for reducing the DAG formation or other may be that at high glycerol concentration water has no effect on glycerolysis. It was seen that, as the water concentration increased, conversion of TAG increased. Formation of MAG and FA also increased while formation of DAG
Propylene Glycol Propylene Glycol is found in antifreeze, it is a humectant which means it is hydrating but is also a skin irritant. It is widely found in skin care products such as body washes, deodorants, shampoo, conditioner and liquid for e-cigarettes. This is because it is cheaper for companies to add this to their products rather than using botanical ingredients. By adding Propylene Glycol it prevents the product from spoiling in hot and cold temperature and helps products to sink into the skin. Although Propylene Glycolic can work into the blood stream.
Dry ice is made from carbon dioxide gas. Carbon dioxide gas is then made into a liquid called liquid nitrogen. Liquid nitrogen is made from CO2. CO2 is made from carbon, oxygen, and oxygen. O2 stands for oxygen times 2.
This experiment was conducted to determine the molar mass of pure water and two unknown substances by finding their freezing point depressions. The experiment was split into two parts: Part One: determining the freezing point depression of pure water and Part Two: determining the freezing point depressions of two separate unknown substances. The molar masses of the two unknown compounds is determined by measuring the freezing point depressions and using water as the solvent. The freezing point of depression is found by utilizing the formula T= Kfm, where T is the difference in freezing points of the solvent and solution, Kf is the freezing point constant for the pure solvent and m is the solution’s molality.
So what is dry ice? As known dry ice is made from carbon dioxide gas. So in particular, it’s actually just solid blocks of carbon dioxide turning into a gas. Now that’s something! As far as we thought, it could have been just blocks of ice blown by a flamethrower.
Introduction The intent of this experiment is to understand how hot and cold water interact with each other by combining clear hot water and black ice cold water. I hope to learn more about how hot and cold water interact with each other. As of now, I know that cold water is denser than hot water. Knowing this I formed my hypothesis.
I chose this Theme because off my parents started a firm that produces dry ice. They started it a few years ago, I remember I was excited about using dry ice because I’d seen some videos about it and I thought it was cool. But when I started to work with it and produce it was not as fun. We fill boxes with 350kg with dry ice, but it takes around 45min to make one box.
First of all we started with 3 water bottles and filled each with 3 substances. The substances were Water, Soap Water, and Milk. We filled each bottle with each substance with about 400mL. After this we measured the height of the bottles with the substances in it and we recorded it down. Than we put the bottles in a freezer for about 72 hours.
It's cold and you hear creeps of footsteps around the corner. It's dark and the atmosphere is damp. You feel something touch your back but when you look back all you see is the flickers of a dark green light a few feet away and white fog arising from the ground. “FIRE!?”
Dry ice is made from raw carbon dioxide gas. Dry ice is the cold dense white mist produced by solid carbon dioxide in the air, used for theatrical effects. Dry ice is called dry ice because it doesn’t melt into a liquid. Dry goes from solid to gas instead of solid to liquid. Dry ice is useful for keeping things frozen.
