In the lab, the theoretical yield of CO2 was calculated by using the mass of the Alka-Seltzer (in Part A) and the mass of the anti-acid (Part B) were multiplied by the mole ratios that were involved in the reaction equation for each reaction and they were also divided by the molar mass of each substance. From the balanced chemical equations that were included in the calculation portion, the limiting reactant in part A was determined to be citric acid. The limiting reactant in part B was determined to be HCl because in the reaction, the HCl would ran out before the calcium carbonate. The stoichiometry would not have been different when converting between the different states of matter because the state is a measure of kinetic energy, and not
Sodium Bicarbonate mixed with Hydrochloric acid. The chemical reaction observed showed that there was fizzing and bubbling, this is evidence that a new gas was being produced. This new gas, CO2 was generated from the reaction. After the fizzing stopped a liquid was leftover leading me to conclude the liquid leftover leading me to conclude the liquid leftover was the NaCl and H2O 4. You found a sample of a solution that has a faint odor resembling vinegar (an acid).
Research Question: To investigate and compare how different temperature (5℃, 15℃, 25℃, 35℃, 45℃) can affect the concentration of carbon dioxide in soda water through titration with sodium hydroxide solution. Introduction: Carbon dioxide plays an important role in soft drinks. Soda water is manufactured by pumping carbon dioxide into water under high pressure. Carbon dioxide dissolves in water to form carbonic acid, which is the fizz we find in soft drinks. CO2 + H2O ⇌
In the Onion's satirical article “Coke’s New 30-Liter Size Bottle: Unwieldy, inconvenient”, written in 2001, corporations are mocked for their dishonesty and misdirection. It reveals corporation’s manipulation of slogans, greed, and view of pity at the consumers. The article supports this claim by first showing a parody of Coke’s community slogan. It uses ridicule to show how “requiring three men to lift the bottle”(5) will promote a community feeling. Then, it depicts the greed that disregards value and products being sold by utilizing a falsely serious tone to describe the flaw of Coke’s carbonation in a 30-Liter bottle “but what are people going to do?
Soda or No Alexeea Swisher Mr.Mosso 1/14/2016 Have you ever thought about having soda machines at school?Why you may ask. Well because soda is awesome,cool and great. If I had a soda machine I would be so grateful. Like I say it’s nutritious and delicious. Well it is not that nutritious or healthy but it is very good.
When I saw Ponyboy asleep on the hospital bed critically burned, I felt my legs giving out. As I glanced to my left, I noticed that Sodapop was tearing up. “Da-r-ry?” Soda managed to mumble out, “ WIll P-p-ony be o-kay?” At that moment I held back another wave of emotion trying to come up, “I don 't know Soda, I just don’t know.
Mika Nijhawan 9/29- 10/10 2 MENTOS AND SODA LAB REPORT State the Problem Does the type of soda affect the size of the explosion, after mentos are added? Develop a Hypothesis If seven mentos to a 2L bottle of Diet Pepsi, then it will create the biggest geyser out of Coke, Fanta, & Root Beer because Diet Pepsi has potassium benzoate, aspartame, and the carbonation which react to mentos. Design an Experiment Materials List: 1 clear test tube 35 original flavored Mentos candies (2 1/2 rolls) 1 3x5 index card 4 2L bottles of soda (all different flavors/types) 1 2L bottle of soda water 1 100 mL graduated cylinder 1 400 mL beaker 1 pair of tweezers (preferably large) 1 small container Procedure: Stack seven mentos in the test tube When given permission take the test tube, soda bottles, index cards, and the remaining 25 mentos, to the designated area Place one of the four soda bottles on a flat area Open the soda bottle and place the 3x5 index card over it With the index card over the soda bottle, flip the test tube over and place it on the index card, so the test tube is lined with
In the crush the can experiment, a soda can was used to show how differences in air pressures may cause the can to “crush” itself. For the experiment, a soda can was obtained and 100 mL of water added. The can was then placed on a hotplate in the”off” position, and then the hotplate was turned on. After waiting for the water in the can to heat to the point where steam could be seen, it was quickly lifted and flipped over into a tub of icy cold water. The resulting reaction was the can crushing.
In the experiment, the chemical rate will be between the baking soda and citric acid as state before. The temperate of the water will have a great effect on the reaction rate because it will either speed up the process or slow it down. The article the effect of temperature on reaction rates states, “As you increase the temperature the rate of reaction increases. As a rough approximation, for many reactions happening at around room temperature, the rate of reaction doubles for every 10°C rise in temperature” (The effect of temperature on reaction rates, 2013). The water that the scientist will be placing the bath bombs in will be room temperature and as soon as you increase that temperature, the rate will increase.
Everyone knows the simple and easy experiment of vinegar and baking soda, but do you really know how it works. This paper will not only explain what makes these two very different chemicals react, but also what materials you will need to accomplish this easy science experiment. Baking soda and vinegar are two different chemical with two very different uses, they are not really even supposed to be used for a science experiment, take vinegar for example, some individuals use vinegar for cooking. Baking soda has a very different use, it is used for bee-stings. When vinegar and baking soda are combined, the hydrogen ions in the vinegar interact with the sodium and bicarbonate in the baking soda.
Then the balloon is lifted up so that the baking soda runs into bottle to react with the vinegar inside. Immediately the balloon is inflated by the carbon dioxide formed. The baking soda is kept constant when the experiment is repeated for another different amount of vinegar. Results/Findings When sodium bicarbonate and vinegar mix,

The Effects of Acetic acid on Sodium Bicarbonate Introduction: Acids and bases are one of the main components of chemistry. They are both substances with unique chemical properties and can use them to neutralize each other. An acid is any substance that produces positively charged hydrogen ions when reacting to a solution containing water. However, a base is a substance that neutralises positively charged hydrogen atoms, which is the reason why an acid and base always form a salt and a water, In this experiment, sodium bicarbonate ( a base) will be combined with vinegar ( an acetic acid) to form Co2 bubbles.
The equation of the reaction between sodium hydroxide and ethanoic acid is as follows: CH3COOH + NaOH → CH3COONa + H2O We can measure the end point of titration process and we can also measure the amount of reactants. The concentration of ethanoic acid in the vinegar can be determined through stoichiometric calculations, Using the values obtained from the titration, and also the chemical equation as a reference. Phenolphthalein indicator is used in this acid-base titration Equipment and materials:
CONCLUSION When you put an egg in vinegar, we see that the shell dissolves, but do you ever wonder why? An egg is made mostly out of calcium carbonate which reacts with an ingredient in vinegar, acetic acid. Acetic acid is about 4% of the vinegar and what breaks apart the solid calcium carbonate crystals. The bubbles we see, from the egg, is the carbonate that make carbon dioxide and the other calcium ions float free. This is the equation: CaCO3 (s) + 2 HC2H3O2 (aq)
