Initial data: m (mass of burned alcohol) = 50 g.

Reference values: according to the condition q (specific heat of combustion of alcohol) = 30 * 10 ^ 6 J / kg.

SI system: m = 50 g = 50/1000 kg = 0.05 kg.

The amount of heat that is released during the complete combustion of 50 grams of alcohol can be calculated using the formula: Q = q * m.

Calculation: Q = 30 * 10 ^ 6 * 0.05 = 1.5 * 10 ^ 6 J or 1.5 MJ.

Answer: D. With complete combustion of 50 grams of alcohol, 1.5 * 10 ^ 6 J (1.5 MJ) of heat is released.
