During this same experiment‚ 26 barrels exceeded the 5% (50ppt) threshold. These were barrels 3‚ 4‚ 6‚ 8‚ 10‚ 11‚ 13‚ 17‚ 18‚ 20‚ 22‚ 24‚ 25‚ 26‚ 27‚ 30‚ 31‚ 34‚ 38‚ 39‚ 42‚ 44‚ 45‚ 47‚ 49‚ and 50 (Table 2a‚ Table 2b). These barrels were not only above the regulated amount‚ but they indicate that measuring using a refractomer would be better to use

Calorimetry Lab Problem: Which foods have the most calories? Hypothesis: If we burn the food then the heating released will be measured as calories because the energy stored inside is released as heat and light. Parts of the experiment Control Group-water Experimental Group- different foods Independent variable- Type of food Dependent Variable- temperature of water Controlled variables- water temperature of unheated water Materials Stirring Rod‚ Beaker‚ ring clamp‚ evaporating disk‚

Egg Lab Write Up The purpose of this lab was to depicked the many properties of diffusion such as isotonic‚ hypotnonic‚ and hypertonic‚ so that students could have a clear visual example to go by for future refrences. We also did this to learn about selective permeability and osmosis. Our original hypothesis stated that the vinegar would react with the calcium in the shell to create CO2 bubbles. Note I said the original hypothesis as this experiment took coarse over a four day period‚ in which

Reconstructing a Cow’s Knee Lab Objective: To learn the function of the knee and how its ligaments work to create the movement the knee makes by taking apart the knee and reconstructing it with different materials to replace the ligaments. Hypothesis: If we replace the cow’s knee tendons with rubber bands then it will work like a new knee because the rubber bands will provide the support‚ strength‚ and flexibility it needs. Safety: Wear gloves while handling the knee‚ use precaution when

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

Enzyme Lab: Peter Kuetzing – 10/4/2012 – F Block 1. How does changing the concentration of enzyme affect the rate of decomposition of H2O2? When more enzymes is added the rate of reaction speeds up. In this case‚ H2O2 will produce more O2‚ in return the kpa/min will go up. 2. What do you think will happen to the rate of reaction if the concentration of enzyme is increased to five drops? Predict what the rate would be for 5 drops. I think that the rate of reaction will slightly increase from
