Unsure how to approach this, reviewing for a test and solved it incorrectly last time so I'd like to know the steps to find this answer.
Consider the following balanced chemical reaction
Mn(s) + 1/2 O2(g) -> MnO(s)
given the reactions below calculate the Delta Hrxn for the formation of MnO(s)
2MnO2(s) -> 2MnO(s) + O2(g) = +272.0 kJ/mol
MnO2(s) + Mn(s) -> 2MnO(s) = -248.9 kJ/mol
