Example #1 2H2(g) + O2(g)  2H2O(g) To react 10.0 g of hydrogen gas, what volume of oxygen gas would you need at 1.05 atm and 22°C? 2H2(g) + O2(g)  2H2O(g)

Example #2 Given 3.00 g of Mg, how much 3.00 M HCl do we need (in mL)? Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)

Example #3 Which case makes the larger balloon (at the same temperature and pressure)? Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g) Case #1: 10.0 g Mg with 586 mL of 3.00 M HCl Case #2: 15.0 g Mg with 274 mL of 3.00 M HCl

Example #4 Consider the reaction: (NH4)2CO3(s)  2NH3(g) + CO2(g) + H2O(g) What total volume of gas is produced, measured at 453oC and 1.04 atm, if 52.0 g of ammonium carbonate is heated?
