Assume that coal is essentially all carbon and has a density of 1.5 g/mL. 1. How much heat is produced if a piece of coal 7cm x 5 cm x 6 cm undergoes complete combustion by the following reaction: C (s) + O2 (g) CO2 (g); AH = -394 kJ 2. What mass of water could be heated from 25°C to 100°C with this amount of heat? (AHrxn = AHproducts – AHreactants; AHrxn = Bond broken - Bonds made) -1.0 x104 kJ, 1.8 x103g of H2O +1.0 x104kJ, 33g of H20 -1.0 x104 kJ, 3.3 x0g of H2O 5.0 x103k), 33 g H20 -5.0 x103k), 3,300g of H20
