Pepsi VS Coca-Cola Keela Murphree Eng 121 Brain Davis 07/18/2011 Pepsi VS Coca-Cola Pepsi and Coca-cola are the most widely recognized beverage brands in the United States formulated by pharmacists. Pepsi and Coca-cola are different in many ways. Pepsi is not as frizzy as Coca-cola. It is sweeter than Coke. After Pepsi sits out a while the taste is stronger.
Put the entire tube in the bottle and replace the cap. As long as the sweets are protected from the soda by the foil, the reaction will not take place. Now shake the soda bottle well and unscrew the cap slightly until you hear a hissing. Throw the bottle into the air so it will hit the ground at a decent velocity. The impact will speed up the reaction and knock the lid off the bottle, which will be propelled up into the
Baking soda is now most often used as a base rather than ammonia for reasons of lowered odor and toxicity; however, any weak base can be used to make crack cocaine. When commonly "cooked" the ratio is 3:4 parts cocaine per bicarbonate. This acts as a filler which extends the overall profitability of illicit sales. Crack cocaine may be reprocessed in small quantities with water (users refer to the resultant product as "cookback"). This removes the residual bicarbonate, and any adulterants or cuts that have been used in the previous handling of the cocaine and leaves a relatively pure, anhydrous cocaine base.
Procedure: 1. The first step we did in our experiment is we took school milk and added it to a little bit of water in a cylinder. 2. Next, we took a flash light and flashed it upward but couldn’t really see any colors. 3.
The effect of high concentrations of sugar in grape juices or any solutions will affect the efficiency of fermentation. 2 Variables Independent: Amount of Sugar (g.)

Will soft drinks dissolve a steel nail? By: Alexis Arms Abstract Is a can of soda strong enough to dissolve a steel nail in only four days? The purpose of this experiment is to test whether phosphoric acid, found in soda, can dissolve a nail or if it’s just a fictitious story. The reason I was interested in this topic is because my father once told me that the phosphoric acid in a can of soda was strong enough to dissolve a steel nail. I searched for answers on the internet but found out that people were on both sides of the fence.
When we increase the temperature of the Hydrochloric acid (HCl) the reaction will be quicker, more gas will be formed in a short amount of time. Because increasing the temperature, the particles move faster the ions have more kinetic energy, causing more collisions. Which will increase the reaction. As the temperature decrease the reaction rate will decrease because the particles have less thermal energy, will travel slower, less collision with other particles as a result of this the reaction rate will be lower. Similarly when the Calcium Carbonate (CaCO3) is broken down into powder the rate of reaction will increase.
Effects of Soda on the Body “It may seem harmless to allow your child to drink soda every day. Thinking that soda won’t cause the child any immediate harm is unfortunately common.” (Khara) Unfortunately for the United States, it’s one of the first countries to start drinking soft drinks. Soda can also be termed as soft drink, coke or fizzy drink and is consumed by all ages worldwide. (Khara) Soft drinks can cause tooth decay, dehydration, obesity and more, and also contain tons of preservatives and artificial sweeteners. It isn’t just parents giving their children soda, it’s also the school districts providing more unhealthy choices and minimal nutritional items, such as milk or water, and fruits and vegetables.
Result: The non-crushed corn worked the best. The crushed corn work but it brut, the non- crushed corn did not burn Discussion: We found that the crushed corn worked better than the non-crushed corn. Conclusion: The crushed corn worked but not to the standards of the non-crushed corn, there so the non-crushed corn worked loads better than the crushed corn The science behind popping corn: Popcorn goes pop because as you heat it up the moisture inside also gets hot and would like to turn into steam. Yet the hard surface coat of the kernel can support up to 10 atmospheres of pressure, stopping the water expanding into steam. The water keeps heating up above 100°C, building up more and more pressure.
However none of this is possible if sugar is not present in the mix. Sugar is the food that yeast relies upon to activate. The more sugar added the greater the gas and the greater the rise. Aim: The aim of the experiment is to see how much carbon dioxide is produced when different amounts of yeast, water and sugar are mixed together in a flask with a balloon covering the opening to capture the gas produced. Hypothesis: If more yeast is added to the mixture then there will be more carbon dioxide created to make the balloon bigger.
