Determine the heat associated with the reaction

Question

Given the balanced thermochemical equation,

2 H2O(l) 2 H2 (g) + O2 (g)                     = +572 kJ

determine the heat associated with the reaction (qrxn) when5.9 moles of O­2(g) are produced. Round and report your answer without any decimal place.

Answer 1

5.9 mol O₂ x 572 kJ/mol O₂ = 3375 kJ
