The amount of heat absorbed in kilojoules when 3.5 moles of water react is 1635.08 KJ
Balanced equation
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ ΔH = 2803 KJ
From the balanced equation for above,
6 moles of water reacted to absorb 2803 KJ of heat
How to determine the heat absorbed
From the balanced equation for above,
6 moles of water reacted to absorb 2803 KJ of heat
Therefore,
3.5 moles of water will react to absorb = (3.5 × 2803) / 6 = 1635.08 KJ of heat
Thus, 1635.08 KJ of heat were absorbed by the reaction.
