We apply Hess's Law and obtain:
2ΔHf(B) + ΔH(reaction) = 2ΔHf(A)
ΔH(reaction) = 2(33.2) - 2(90.2)
ΔH(reaction) = -114 kJ / mol
I need to comment on this sorry
Answer:
hope this helps
Explanation:
the denser plate will subduct under the plate that is less dense, creating a deep sea trench at the point of subduction. As the subducted plate goes deeper into the mantle, the mantle material above it starts to melt to become magma
The first one is the second one and the second one is the first one
