Calculate the heats of reaction for the following unbalanced reactions. Then use Hess' law to find the heat of reaction for the overall process.
a) Equation1: CaCO3(s)= CaO(s) + CO2(g)
Equation2: CaO(s) + Fe(s) = Fe3O4(s) + Ca(s) in acid solution catalyst
b)Is the overall process exothermic or endothermic?
c) If 5.794 kg of calcium carbonate react in reaction above, how much heat os either produced or needed?
d) How many grams of iron metal are required for this reaction?
