Question

You have a series of four chemical reactions (1->2->3->4). How do you calculate the triangleH2 if you know the other triangleH values?
A. Triangle H2= triangleH1 + triangleH3 -triangleH4

B. Triangle H2= triangleH1 + triangleH3 + triangleH4

C. Triangle H2= triangleH4 - (triangleH1 + triangleH3)

D. Triangle H2= (triangleH1)(triangleH3)(triangleH4)

Answer 1

Given:
Δ H1 → Δ H2 → Δ H3 → Δ H4


Answer would be:

C. Triangle H2 = Triangle H4 - (Triangle H1 + Triangle H3)

Your basis would be triangle H4. If you're looking for triangle H4, simply add triangles H1 to H3.
