Answer 1

Answer #1

Number of moles of H2 = 4.85 g / 2.016 g/mol = 2.41 mole

From the balanced equation we can say that

2 mole of H2 requires 572 kJ of heat so

2.41 mole of H2 will require

= 2.41 mole of H2 *(572 kJ of heat / 2 mole of H2)

= 688 kJ of heat

Therefore, the amount of heat produced would be +688 kJ
