Question

Heat of combustion of glucose at 18°C and constant

pressure is 652 kcal. Calculate its heat of combustion at

constant volume. (R = 2 cal K–1 mol–1)​

Answer 1

Answer:

The heat of combustion is calculated by multiplying the mass of the water times the specific heat of the water times the change in temperature. This entire equation is multiplied by -1, because heat of combustion is negative because heat is being lost or released.
