1)When Fe(s) reacts with HCl(aq) to form FeCl2(s) and H2(g), 7.40 kJ of energy are evolved for each mole of Fe(s) that reacts. Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation.

2)When N2(g) reacts with O2(g) to form NO2(g), 66.4 kJ of energy are absorbed for each mole of N2(g) that reacts.Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation.
