MACROMOLECULS LAB: What are the mystery powders? Period: 4 Asia Enoch Introduction: A carbohydrate is an immediate form of energy in your body. Monomers is smaller than a polymer. For carbohydrate the monomer is sugar and the polymer is a polysaccharides. Carbohydrates are important to our body because we need to use energy. The purpose of this lab is to figure which one is the monomer and which one is the polymer. Hypothesis: If I place two drops of iodine into the mystery powder‚ it

Introduction The purpose of this lab was to test different antacids‚ to find out which would be the most effective to take. Stomach acid problems come from a overproduction‚ and build up of gastric acid (HCl). In order to determine which antacid is the more effective‚ four different brands of antacids were chosen‚ and tested. The purpose of an antacid is to balance out the pH inside a person’s stomach. PH is the measurement of molar concentration of hydrogen ions that are present in the solution

The purpose of this lab was to see which solutions are soluble and which are not. We were able to see this by mixing certain solutions together and observing changes that occurred. The procedure for this experiment included a few different steps. The first steps were to add the nitrate solutions into the lettered parts of the 96-well plate. Once you were done with that‚ you were supposed to add the sodium solutions to the numbered parts of the 96-well plate‚ so that the solutions were added together

Tyler Cowan Professor Foltz Biology 181 April 8th 2015 Lab Report: Respiration Abstract: The objective of this lab was to figure out which has a higher cell respiration rate between crayfish and elodea. In order to figure this out we first set up three beakers to represent our control‚ elodea and crayfish and filled them with 75mL of culture solution which were dechlorinated making the solution acidic. We then had to place both the elodea and the crayfish in separate beakers filled with 25mL of

Lab Report Abstract: The purpose of this lab was to see how magnesium reacts with oxygen. This reaction must be forced with heat. As magnesium changes to magnesium oxide the mass increased. Procedure: 1. Set up the stand and bunsen burne. 2. Go to crucible heat oven to obtain a crucible. 3. Weigh the crucible and lids mass. 4. Break up the magnesium ribbon on the crucible and weigh the mass of the magnesium‚ crucible‚ and lid. 5. Place the crucible on the ring stand over the flame. Allow
