13. Balancing equations. 5 pts Examples: 1. N2(g)+H2(g)NH3(g) - To balance H, we place 2 before NH3 and 3 before H2 N2(g)+3H2(g)2NH3(g) 2. C6H6(g)+O2(g)CO2(g)+H2O(1) - Start with C by placing 6 before CO2 and H by placing 3 before H2O and 15/2 before O2 to give: C6H6(g)+15/2O2(g)6CO2(g)+3H2O(l - This is balance but contains fraction, to eliminate ,we multiply by 2 to give: 2C6H6(g)+15O2(g)2CO2(g)+6H2O(l) 3. Ba(OH)2(aq)+H3PO4(aq)Ba3(PO4)2(s)+H2Ol) - Start with Ba by placing 3 before Ba(OH)2 and 2 before H3PO4 and for H place 6 before H2O 3Ba(OH)2(aq)+2H3PO4(aq)Ba3(PO4)2(s)+6H2O(I) Balance the following by inspection. 1. HCl+CaCO3CaCl2+CO2+H2O 2. CH4+O2CO2+H2O 3. BCl3+P4+H2BP+HCl 4. NaNO3NaNO2+O2 5. SrSO4+H3AsO4H2SO4+Sr3(AsO4)2
