--------------------.---124Chapter ThreeStoichiometryIf a container were to have 10molecules of O2and 10moleculesof NH3 initially, how many total molecules (reactants plus prod-ucts) would be present in the container after this reaction goesto completion?109. Ammonia is produced from the reaction of nitrogen and hydro-gen according to the following balanced equation:Nig)+3Hig) ~2NH3(g)a. What is the maximum mass of ammonia that can be producedfrom a mixture of 1.00 X 103g N2 and 5.00 X 102g H2?b. What mass ofwhich starting material would remain unreacted?110. Consider the following unbalanced equation:Ca3(P04Ms)+H2S04(aq) ~CaS04(s)+H3P04(aq)What masses of calcium sulfate and phosphoric acid can be pro-duced from the reaction of 1.0 kg calcium phosphate with 1.0kg concentrated sulfuric acid (98% H2S04by mass)?111. Hydrogen cyanide is produced industrially from the reaction ofgaseous ammonia, oxygen, and methane:2NH3(g)+302(g)+2CH4(g) ~2HCN(g)+6H20(g)If 5.00 X 103kg each ofNH3, O2,and CH4are reacted, what massof HCN and of H20 will be produced, assuming 100% yield?112. Acrylonitrile (C3H3N) is the starting material for many syntheticcarpets and fabrics. It is produced by the following reaction.
