iced water (10 degrees) had the slowest rate of reaction at 1.10 minutes. Then the room temperature water (19 degrees) was tested and had a slightly better rate of reaction at 1.09 minutes. Then last of all‚ we tested the boiling water (63 degrees) which had a large improvement from the last two with a rate of reaction of 43.5 seconds. This showing development in the rate of reaction in all three experiments and that the higher the temperature the faster the rate of reaction is. The results were precise

higher than what is believed to be healthy‚ it considers as a serious condition that increases the risk of cardiovascular disease. The higher your blood cholesterol level‚ the greater your risk of cardiac arrest. How does a high cholesterol affect Your Heart? When your level of cholesterol in your body is high‚ the excess oily stuff will stick to the walls of your arteries. Over time‚ this excess can create a fatty

were going to be most active at the 41ᵒC which is close to human body temperature. When we compare the enzyme in the low temperatures to the enzymes in the higher temperature we observed that the enzymes were functioning at a significantly reduced rate at the 24ᵒC temperature and was completely inactive at the 0ᵒC temperature. Whereas when we compare to the higher temperatures (60ᵒC) the enzymes should have functioned with reduced efficiency and should have even denatured which would

Due to the fact that it would be closer to the light source‚ the light would be slightly more intense‚ therefore the rate of photosynthesis would be slightly more advanced‚ causing a lower absorption. I also believed that Sample 1 the sample wrapped in aluminum would have the highest absorbance due to a lack of

Title: Factors affecting reaction ratesProcedure A: Effect of ConcentrationAim: To investigate how the concentration of a reactant affects the rate of reaction. Hypothesis: The more concentrated the reactant‚ the faster the rate of reaction. Materials: 2M hydrochloric acid solution‚ magnesium wire‚ distilled water‚ 4 test-tubes‚ measuringcylinder. Procedure:1)10mL 2M hydrochloric acid solution is poured into a test-tube using a measuring cylinder. 2)A 3cm length of magnesium wire is added to

Chemistry Lab Report (Design) Factors affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to

Main factors affect the refined oil yield: 1‚ the alkali refining loss (1) for removal of colloid in hair oil‚ free fatty acid‚ moisture‚ impurities and other form of loss; (2) in the process caused by the loss of neutral oil saponification‚ emulsification; (3) theoretical calculation formula: alkali refining losses = 0.2 + 1.25 x (FFA % % + water + phosphatide content % % + 0.3% + impurities) 2‚ decoloring loss mainly for adsorption bleaching waste clay in oil absorption caused by the loss

exercise affect your breathing and heart rate?” and my hypothesis was “If you exercise then your heart and breathing rates will go up because your body needs more oxygen to be circulated so that your body can keep up.”. My hypothesis was correct‚ as proven by my test. My partner‚ Brian’s heart rate when it was resting was 56 beats per second and his breathing rate was 40 beats per second. We made him do jumping jacks for ten seconds and his heart and breathing rates both went up. His heart rate increased
