Answer: To calculate the enthalpy of combustion of acetylene, C2H2 , all you have to do is ... More specifically, you need to subtract from the sum of enthalpies of ... chemical reaction has 2 moles of C2H2 reacting to produce 2 moles of ... since the heat of combustion is expressed as energy per mole
None of above. only temperature stays constant.
