Lab Report11/5/17Jade McCorbinDetermination of Ideal Gas Law ConstantPurpose: To determine the ideal gas law constant, using a catalyst to initiate an oxidation –reduction reaction, and use the ideal gas law to determine the number of moles of gas isgenerated in a reactionEquipment/Materials:·15mL Bottle·Plastic Tubing·Yeast Packet·3% Hydrogen Peroxide·10 mL Graduated Cylinder·50mL Graduated Cylinder·250 mL Beaker·Weigh Boat·Tap WaterBalanced Equation: 2 H2O2 à 2 H2O + O2Results:As each trial required more hydrogen peroxide, gas inside the bottle containing yeast cause anincrease in gas in the graduated cylinder. The bottle that contained yeast and hydrogenperoxide increased in temperature and bubbled in response to the reaction between the H2O2and yeast. The yeast acted as a catalyst aiding the produced gas to react faster. In trial 1/2, 1mlof hydrogen peroxide was used with .01g of yeast and this yielded a 9mL change in volumeproduced by the gas. In trial 3/4, 2mL of hydrogen peroxide were used which resulted in a 17mLchange in volume produced by the gas. In trial 5/6, 3 mL of hydrogen peroxide was used whichresulted in 22mL change in volume. In trial 7/8, 4 mL of hydrogen peroxide were used and this
