Is the following reaction endothermic or exothermic?
please help will greatly appreciate
Homework Answers
combustion of methane is always an exothermic reaction.Combustion involves the addition of oxygen molecule,in combustion always energy is released and this energy is used to break the bonds.
here CH4+ O2 -----> CO2+ H2O delta H=-21 KCal
