To do that, I needed: A graduated cylinder, a beaker, a calculator and a weight scale, along with small amounts of Classic Coke and Diet Coke. The measurements required were volume and mass to find the density; the units used in the findings of the mass was grams (g) and for the volume, milliliters (ml). The final measurement unit was set as (g/ml). First, I weighed the graduated cylinder to see its weight without any soda so that measurement could be used a bit later. Next, I poured a specific amount of each soda into the graduated cylinder to measure its weight with the soda (the amount used was the volume).
Results Sheet, Experiment 13 Brand of Vinegar used:________________ Acetic Acid % from bottle label_____________ | Initial NaOH Reading(estimate to 0.1 mL) | Final NaOH Reading(estimate to 0.1 mL) | Volume NaOH used(Final – Initial) | Trial 1 | 9.5 | 1.3 | 8.2 | Trial 2 | 9.6 | 1.4 | 8.2 | Trial 3 | 9.7 | 1.4 | 8.3 | Average Volume of NaOH used | 8.2 | Calculations: Normality of the acetic acid: .82 Mass of acetic acid: 49.2 % acetic acid (divide the grams, above, by the volume you used to get g/L): 4.92 Answer questions A-G in the lab manual: A. What is the average % acetic acid in your vinegar sample? Standard vinegar is 5% acetic acid. How does your result compare with the standard? The average was 4.92 which is pretty close comparably to the standard.
Brendan Dennis 2/24/13 CP Biology Enzymes Used vs. Amount of Apple Juice Produced Lab Report Title: Enzymes Used vs. Amount of Apple Juice Produced Problem: How does a change in the enzymes used affect the amount of apple juice produced? Hypothesis: If different enzymes, such as pectinase and cellulase, are used to break down apple sauce, then the most apple juice will be produced when 5 drops of both pectinase and cellulase are used in one mixture because the two enzymes will be working together to break down the apple juice. Procedure: 1.
Physical b. Pulp-free orange juice is prepared by filtering most of the pulp from fresh orange juice. Physical c. The compound glycerin, which is used in lotions, is formed as a byproduct during the preparation of biodiesel fuel from waste restaurant oils. Chemical 4. Identify each of the following as a substance or a mixture: (3 points each, 12 points total) a. helium gas that is used to fill a balloon Substance b. the juice that is squeezed from an orange Mixture c. distilled water Mixture d. carbon dioxide gas Mixture 5. An advertisement for shampoos says that it is pure shampoo, with nothing artificial added.
Question: What number of Mentos need to be dropped into a bottle of Diet Coke in order to get the maximum amount of soda displaced? Hypothesis: We believed that because of the relatively small size of the bottle, the greatest amount of soda displaced would be achieved when 5-6 Mentos were dropped into it. We chose this amount because after watching numerous videos, this looked to be the most popular amount. Research: To figure out why the two products reacted in a geyser-like way, we researched (both by text and online), and found good explanations from The Encyclopedia of Earth and Physical Science, The McGraw-Hill Encyclopedia of Science and Technology, and Science and Technology Illustrated. We related these explanations to our experiment, figuring that if you use too few mentos, there would only be a minimal amount of "fizzing," displacing a small amount of soda.
Renaissance physician Paracelsus famously said, "The dose makes the poison," meaning that even harmless substances can become toxic if you eat enough of them. Many people ask me, "Is high fructose syrup really that bad for you?" And my answer to this question is "Yes," mainly for this very reason. In America today, we are eating huge doses of sugar, especially high fructose corn syrup. It is sweeter and cheaper than regular sugar and is in every processed food and sugar-sweetened drink.
On the first bottle I learned how to spew Pepsi all over the room. For the other two bottles I found that each one contained about 2.2 grams of carbon dioxide under pressure dissolved in the liquid! That is enough gas to fill up a liter bottle at standard temperature and pressure! This is not all of the carbon dioxide in the soda. There is still carbon dioxide gas dissolved in the liquid at atmospheric pressure.
Some fruits are sweet as well as sour in taste like orange, as it has almost equal quantities of fructose and acids in it. Fruits like lemons have sour taste; they do not get sweet taste even after ripening due to the presence of excessive amount of acids. Raw bananas have more starch but when the fruit gets ripen, the starch gets converted into fructose. The chemical changes take place inside the fruit during the process of ripening, due to these changes the amount of sugar increases in fruit and it becomes sweet. You will see that even two fruits of same type have different taste like two mangoes or two apples do not have same taste but they are different in taste.

The main difference between hemp and marijuana is the concentration of THC. The amount of THC in hemp is much lower at approximately 0.3% compared to marijuana which can be anywhere from 5-25%. The fact that hemp contains THC has been a major argument for not legalizing it in the United States. The truth is hemp has such a low concentration of THC a recreational marijuana smoker could smoke an acre of it and get nothing more than a headache for their efforts. (Earlywine) Hemp has been cultivated world wide throughout history with the earliest use dating back more than 8000 years ago in Taiwan.
