Polychlorinated biphenyls (PCBs), which were formerly used in the manufacture of electrical transformers, are environmental and health hazards. 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 HCI (a) How many moles of water are needed to react with 16.0 mol O₂? i mol H₂O (b) How many grams of HCI are produced when 19.3 mol H₂O react? x 10 g HCI (c) How many moles of CO₂ are produced when 98.153211351738 g HCl are produced? mol CO₂ (d) How many grams of C12H4Cl6 are reacted when 101.14 g of CO₂ are produced?Note: Use three significant digits in your answer. i 8 C12H4Cl6 (e) How many grams of HCI are produced when 6.1 kg C12H4Cl6 react? x 10 g HCI
