1. A sample of 10.7 g of CO reacts completely with O2 to form CO2. How many grams of CO2 will be formed?
2. Urea (NH2)2CO is prepared by reacting ammonia with carbon dioxide. The byproduct is water. 637.2 g of ammonia are reacted with 787.3 g of carbon dioxide. Which of the two reactants is a limiting reactant.
Convert each reactant to moles, then use the coefficients in the balanced equation to convert EACH reactant to moles of the product. The two answers can't be right; the correct answer in limiting reagent problems is ALWAYS the smaller value and the reagent producing that value is the limiting reagent.
