What is the Delta. Hf for this reaction? 16CO2(g) + 18H2O(g) Right arrow. 2C8H18(l) + 25O2(g)

10,148

Explanation:

The Hrxn for the reaction C(s) + O2(g) -> CO2(g) is the same as the Hf for CO2(g).

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

The Hrxn for the reaction 1.5H2(g) + 0.5N2(g) -> NH3(g) is the same as the Hf for NH3(g).

Explanation:

it means there are 3 atoms of oxygen
