Alaboratory manual gave precise instructions for carrying out the reaction described by the chemical equation, c2h6o + o2 c2h4o2 + h2o. it stated that if you bubble oxygen gas through a solution containing the reactant for 24 hours then the yield of c2h4o2 would be 7.50% of the theoretical amount. if you desire to produce 700. grams of the c2h4o2 in a single batch, how many kg of c2h6o should you begin with?
