The Effect of Sugar Type on Rate of Energy Production During Yeast Fermentation Sarah Sulon Biology Lab 111L Dr. Murray October 25 2010 Abstract The experiment was conducted to determine the impact different sugar types have on yeast fermentation. It was hypothesized that glucose‚ sucrose and fructose would all produce energy through yeast fermentation‚ but that sucrose would have the greatest rate of energy production. The carbon dioxide production was tracked in the fermentation of yeast

Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI‚ represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely

rapid increase in breath rate. Normal resting breath rate is at an average 11.6 breaths per minute increased to 27 breaths per minute after exercise. The increase in BR causes expiration length to go below its normal 3 second interval. Therefore decreasing ERV by .6 Liters. Inspiratory reserve volume decreased due to the rapid increase in breath rate. Normal resting breath rate is at an average 11.6 breaths per minute increased to 27 breaths per minute after exercise.

The Effects of Gun Control Law on Violent Crime Rates Emily JettCSCI N207Final Project12/8/2012 | Abstract: This paper discusses the relationship between violent crime rates in each state as well as that state’s corresponding gun control laws. The data is presented to provide information pertaining to the theory that stricter gun laws prevent higher rates of violent crime. Violent crime statistics were taken from The United Crime Report document from the Federal Bureau of Investigation’s website

Topic: The effects on China’s economy due to fluctuation of exchange rate. 1. Introduction China’s economy is huge and expanding rapidly. In the last 30 years‚ the rate of Chinese economic growth has been almost miraculous‚ averaging 8 percent growth in Gross Domestic Product (GDP) per annum. The economy has grown more than 10 times during that period‚ with Chinese GDP reaching 3.42 trillion US dollars in 2007. China already has the biggest economy after the United States and most analysts

Problem Question: * What effect does temperature have on the rate of Diffusion? Hypothesis: If we put the antacid in hot water‚ then it will dissolve faster than in cold water or room temperature water. Material List: * One thermometer * 3 beakers (of the same size) * 3 antacid tablets * Cup of ice * Hot plate * Paper towels * Water Procedures: Step 1: Gather materials Step 2: Label the beaker #1‚ #2‚ and #3 Step 3: Fill each beaker with the same amount of

Evaluation Like any experiment‚ there were a number of potential errors during the procedure of the experiment. Errors could have arisen as a result of the uncertainties associated with the instruments I used to take measurements‚ and also as a result of errors associated with the actual method. Of course‚ due to the limitations of the procedure‚ they could not be eliminated completely‚ so I will explain what I did to reduce them to an acceptable level and how I could have improved my method to

EFFECT OF ROOM TEMPERATURE ON THE BURN-RATE OF A CANDLE BURNS Have you ever wondered whether a candle burns more quickly on a hot day‚ than on a cold day? Or is it the other way around? This science fair project was carried out to compare how quickly a candle will burn at different room temperatures. The experiment was done by measuring how much of a candle will melt in 30 minutes when placed in an environment with surrounding temperatures of 20°C‚ 25°C and 30°C. Hypothesis A candle in a colder
