A sample of iron metal is placed in a graduated cylinder. It is noted that 10.4 mL of water is displaced by the iron. The iron is then reacted with excess hydrochloric acid to produce iron (II) chloride and hydrogen gas. Given the density for iron is 7.86 g/mL, how many grams of iron (II) chloride are produced in the reaction? Fe(s) + 2HCl(aq) –> FeCl2(aq) + H2(g) 

What is the theoretical yield of ammonia that can be obtained from the reaction of 10.0 g of H2 and excess N2? N2 + 3H2 –>2NH3 

Sulfur dioxide gas reacts with oxygen gas and water according to the chemical reaction below. When 4.5 g of SO2 are mixed with excess O2 and H2O, how many grams of H2SO4 are produced? 2SO2(g) + O2(g) + 2H2O(l) –> 2H2SO4(l) 

Determine the number of moles of water produced by the reaction of 155 g of ammonia and 356 g of oxygen. 4NH3 + 5O2 –> 4NO + 6H2O
