Question

the chemical reaction above releases about 2200 kJ of energy. How much energy is released when 2 miles of A^3 B^8 combusts

Answer 1

If there are 2200 kJ of energy released when 1 mol of A^3 B^8 combusts, then combustion of 2 moles of A^3 B^8 will produce $2\times2200=4400 \ kJ$

Answer: E = 4400 kJ.
