Upon complete combustion, the indicated substances evolve the given quantities of heat. Write a balanced equation for the combustion of 1.00 mol of each substance, including the enthalpy of reaction, Δ_rH, for the reaction.

(a) 0.584 g of propane, C₃H₈(g), yields 29.4 kJ 

(b) 0.136 g of camphor, C₁₀H₁₆O(s), yields 5.27 kJ 

(c) 2.35 mL of acetone, (CH₃)₂ CO(l) 1d = 0.791 g/mL₂, yields 58.3 kJ
