Question

methanol CH3OH is used as race car fuel  write the balanced equation for the combustion of methanol.  change in heat= -174kcal/mol methanol for the process  How man kilocal are released u burning 33.0g of methanol

DrBob222 · Answer

2CH3OH + 3O2 => 2CO2 + 4H2O dH = -174 kcal/mol and that x 2 = -348 kcal/rxn and I'm taking you at your word that this is -174 kcal/mol and not -174 kcal/reaction for the 2 mols.

-348 kcal x 33.0/64 = ?
