Determine the standard enthalpy change for the formation of water (H2O) when hydrogen gas (H2) reacts with oxygen gas (O2) according to the balanced equation:2H2(g) + O2(g) → 2H2O(l)Given that the standard enthalpy change of formation for H2O(l) is -285.8 kJ/mol, calculate the amount of heat absorbed or released when 4.50 moles of H2O(l) is formed under standard conditions.
