Butane (C4H10) undergoes combustion in excess oxygen to generate gaseous carbon dioxide and water.How much energy is released (kJ) when 12.45 g of butane is burned? Given: AH[C4H10(g)] = -124.7 kJ/mol, AH [CO2(g)] = -393.5 kJ/mol. AHf[H2O(g)] = -241.8 kJ/mol A 190.1 kJ 960.8 kJ 570.2 kJ 380.1 kJ (6 412.2 k)
