Polychlorinated biphenyls (PCB) are environmental and health hazard. They break down very slowly in the environment. The decomposition of PCBs can be represented by the equation:

2 C12H4Cl6 + 23 O2 + 2 H2O --> 24 CO2 + 12 HCl

a) How many moles of water are needed to react 10.0 mol PCB?

b) How many grams of HCl are produced when 15.2 mol H2O react?

c) How many moles of CO2 are produced when 76.5g HCl are produced?

d) How many grams of PCB are reacted when 100.25g CO2 are produced?

e) How many grams of HCl are produced when 2.5kg of PCB react?
