Initial data: m (mass of completely burnt wood) = 500 g (0.5 kg); we assume that we burned dry wood.

Reference values: q (specific heat of combustion of dry wood) = 10 MJ / kg (10 ^ 7 J / kg).

The amount of heat that will be released from the combustion of dry firewood is calculated using the formula: Q = m * q.

Calculation: Q = 0.5 * 10 ^ 7 = 5 * 10 ^ 6 J (5 MJ).

Answer: 5 MJ of heat will be released.
