Question

2H2+O2 -> 2H20 changeHrxn=-484 KJ

Which answer best describes the transfer heat that occurs when 1.30 mol of H2 reacts?

629 KJ released
315 KJ absorbed
315 KJ released
484 KJ absorbed
484 KJ released
629 KJ absorbed
The sign is negative which means the heat is released. That makes three answers (absorbed) go away.
(484/2 mol) x 1.3 mol = ?
