The main objective of this lab was to collect 〖Co〗_2 gases that were given off by the Alka-Seltzer tablets and to identify experimental masses. The volume of gas was 724 liters, or 723.86 cm and the experimental mass was .0894 grams. A balance scale was used before and after the reaction to record the change in overall mass. First, using the scale, the flask, balloon, and Alka-Setlzer tablets were measured, 259.4 ±.05 Grams were found. What created the “〖Co〗_2 gases to be trapped” were the…

In this investigation, the mass (g) of a beaker and a graduated cylinder were calculated and recorded into a lab notebook. The density of distilled water was calculated without any NaCl by measuring the mass of a sample of water in a beaker, and then subtracting the mass of the beaker to leave the mass of water. This measurement was recorded into a lab notebook in Table 1 under “Total Mass of Solution” and “Mass of solution”. The contents of the beaker are then transferred to a graduated…

Thermodynamics of Cheetos Purpose: to analyze the caloric content of snack foods, by determining the calories of heat given off by a Cheeto, or other snack foods, as it burns. Procedure: The food sample (Cheeto) was placed on a food holder, and the initial combined mass of the food holder and the Cheeto was measured and recorded. Using a graduated cylinder, 50-100 milliliters (ml) of water was measured and added to an empty soda can that was cut in half and cleaned. The soda can was…

Aim: The aim of this investigation is to determine the effect of water temperature on the time it takes for an aspirin tablet to dissolve. Hypothesis: The boiling water will have the quickest time to dissolve the aspirin tablet. This is because its molecules have more energy and are vibrating more rapidly than the cold water. Cold tap water will have the slowest time to dissolve the aspirin tablet because it has the least kinetic energy. Why? Apparatus: Equipment: Image Kenwood Kettle Pyrex…

Frame: The purpose of this lab is to determine if the iron given in the experiment is Fe (II) or Fe (III). Knowing what chemicals are present in a reaction and what chemicals are produced is significant information that can be applied to real world situations. An example of this is rust. Rust usually occurs when iron reacts with water. By being aware of this, substances can be made to remove unwanted rust. The mass of the collected samples will decrease as it is dried due to evaporation. Excess…

your regular trash in every state except California, where they must be recycled. After disposing of leaking batteries, you may need to clean the device they were in. Although people often refer to battery acid, potassium hydroxide is a base. To remove it from a device's battery contacts, use an acid like lemon juice or vinegar and a cotton swab.…

The water bottle brand Poland Springs had mostly clear water, it was extremely transparent, except there was a very light gray tint to the water that was barely noticeable. Also, when the water was first poured into both warm and cool temperature test tubes, there were some air bubbles in the test tubes. However, after 2 days, the bubbles seemed to have disappeared from both test tubes in both environments. Within both environments there was evaporation, however, evaporation along with water…

Have you ever wondered witch pop has the most fizz. Well in this paper I will tell you what carbonation is. How you can do this experiment at home. I will be telling you some history about who envented carbonation. Carbonation is a really cool thing when you think about it. It takes about 2 minutes to make 12 cans of pop. Different chemicals are added to the water to remove any tiny particles plus kill any bacteria that might be in it. The water is also run through a series of special filters…

levels fluctuate from 6.0 before exercise, to 4.5 immediately after exercise, to 5.0 six hours after exercise. This informs Tracey that Max’s kidneys are working to level off his pH to normal levels over time. During exercise, the body produces lactic acid, a waste product which causes the pH to drop. The kidneys release more hydrogen ions which cause the pH to decrease and make urine more acidic while the blood becomes more basic. After exercising, the kidneys don’t release as many hydrogen…

Purpose This lab’s purpose was to experiment how much of a syrup solution would seep through a dialysis bag at different temperatures. Procedure We prepared by filling up three dialysis bags with about 100 mL of a syrup solution. We tied knots on either end and measured the initial mass of the bags. The bags were measured in grams. Then we added water to three different beakers, each being a different temperature. One beaker was room temperature, another was heated to about body temperature…
