E+A------2D=+350
For B+D=E+2C ∆H will be?
​

Answer 1

Answer:

-175

Explanation:

0.5A-----B-> 150

A-----2B-> 300--------(1)

E+A-----2D-> 350------(2)

Subtracting (1) from (2)-> E+2B------2D->50-----(3)

3B---------2C+D--> -125---------(4)

Subtracting (3) from (4)------->  B+D--------E+2C-----> -125-50=-175
