Ammonia gas combines with solid copper(II) oxide to yield nitrogen gas, copper metal, and steam.
Part 1: What is the unbalanced equation (no stoichiometric coefficients, reactants on left, products on right, separated by an arrow, and phases are not necessary).
Part 2: What is the balanced equation in standard form? Stoichiometric coeffcientst should be the lowest set of whole numbers
Part 3: How many moles of H2O can be formed when 4.50g of CuO are combined with 4.50 x 1023 molecules of ammonia. (three significant figures)? (If the balanced equation is not correct for part B, this part will most likely be incorrect)

Solid copper can be produced by passing gaseous ammonia over solid copper (II) oxide at high temperatures. The other products of the reaction are nitrogen gas and water vapor. The balanced equation for this reaction is: 2NH3(g)+3CuO(s)->N2(g)+3Cu(s)+3H2O(g) What is the theoretical yield of solid copper that should form when 18.1 g of NH3 is reacted with 90.4 g of CuO? If only 45.3 g of copper is actually collected, what is the percent yield?
