Consider the following reactions:
A + 2B → C + D ?H = -68 kJ
E + 2B → C + F ?H = 188 kJ
F + G → D ?H = -79 kJ
What is ?H for E + G → A ?
It is possible that your answer could be either positive or negative. If it is negative, you must include the "minus" sign. Enter your answer as a decimal number.
