how do i solve this thermochemical equation? and what r the steps to it
1. Find the heat of reaction for the following equation.
N2(g) + 2 O2(g) -> N2O4(g)
given the following steps
2NO2(g) -> N2(g)+ 2O2(g) delta H=-84.8 kj
N2O4(g)-> 2NO2(g) delta H= 72.8 kj
if you can solve this that would be really great thank you. and there might be more
