Given the following data:

Question

MnO(s) + H2(g) Mn(s) + H2O(l), H = 100 kJ
MnO2(s) + 2 H2(g) Mn(s) + 2 H2O(l), H = –52 kJ
use Hess's law to calculate the heat of the reaction
MnO2(s) + H2(g) MnO(s) + H2O(l)

Answer 1

Given the following data:
MnO(s) + H2(g) Mn(s) + H2O(l), H = 100 kJ
MnO2(s) + 2 H2(g) Mn(s) + 2 H2O(l), H = –52 kJ
use Hess's law to calculate the heat of the reaction
MnO2(s) + H2(g) MnO(s) + H2O(l)
