GPT 3.5
To find the total energy released when 7.7 mol of C reacts, we need to multiply the amount of C reacted by the heat of combustion reaction.
7.7 mol C x 94. kcal/mol = 727.8 kcal
Therefore, when 7.7 mol of C reacts, 727.8 kcal of energy is released.
7.7 mol C x 94. kcal/mol = 727.8 kcal
Therefore, when 7.7 mol of C reacts, 727.8 kcal of energy is released.
