Which statements are true? A combustion reaction is exothermic. Δ H ΔH for an exothermic reaction is positive. The evaporation of water is an exothermic process. When energy is transferred as heat from the system to the surroundings, Δ H ΔH is negative. When energy is transferred as heat from the surroundings to the system, Δ H ΔH is negative. Δ H ΔH for an endothermic reaction is positive.
