Is temperature equal to heat
Witryna19 cze 2024 · Δ H f o for NO ( g) = 90.4 kJ/mol Δ H f o for O 2 ( g) = 0 (element) Δ H f o for NO 2 ( g) = 33.85 kJ/mol Unknown First write the balanced equation for the reaction. Then apply the equation to calculate the standard heat of reaction from the standard heats of formation. Step 2: Solve. The balanced equation is: 2 NO ( g) + O 2 ( g) → 2 … WitrynaIn all cases, the amount of heat lost by a system is equal to the amount of heat gained by its surroundings and vice versa. That is, the total energy of a system plus its surroundings is constant, which must be true if energy is conserved.
