Question
Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation. Note that the answer box for the energy term is case sensitive.
Use the SMALLEST INTEGER coefficients possible and put the energy term (including the units) in an appropriate box. If a box is not needed, leave it blank.

Explanation / Answer
1) CO(g) + 1/2 O2(g) ------ > CO2(g) +283 kJ
2) 3Fe2O3(s) + H2(g) ------ > 2Fe3O4(s) + H2O(g) + 6.00 kJ
