Which of these statements are true? Select all that apply. The Delta.Hrxn for the reaction C(s) + O2(g) Right arrow. CO2(g) is the same as the Delta.Hf for CO2(g).

The Delta.Hrxn for the reaction Na(s) + Cl2(g) Right arrow. 2NaCl(s) is the same as the Delta.Hf for NaCl(s).

The Delta.Hf for Br2(l) is 0 kJ/mol by definition.

To determine the Delta.Hf for H2O(g), just reverse the sign of the Delta.Hrxn for the reaction 2H2O(l) Right arrow. 2H2(g) + O2(g).

The Delta.Hf for N2(l) is 0 kJ/mol by definition.

The Delta.Hrxn for the reaction 1.5H2(g) + 0.5N2(g) Right arrow. NH3(g) is the same as the Delta.Hf for NH3(g).
