Answer to Question #55402 in General Chemistry for kaitlyn
Question #55402
How much heat is produced by the complete combustion of 244 g of CH4?
CH4(g)+2O2(g)→CO2(g)+2H2O(g)ΔH∘rxn=−802.3kJ
CH4(g)+2O2(g)→CO2(g)+2H2O(g)ΔH∘rxn=−802.3kJ
Expert's answer
Q = n (-ΔH∘rxn) = m M-1 (-ΔH∘rxn) = 244 g (-802.3 kJ mol-1) /16.04 g mol-1 = 12205 kJ = 12.2 MJ
Answer: 12.2 MJ
Answer: 12.2 MJ
