One mole (mol) of nitrogen monoxide (NO) has a mass of 30.01 g. When precisely 2 moles of NO(g) are produced


One mole (mol) of nitrogen monoxide (NO) has a mass of 30.01 g. When
precisely 2 moles of NO(g) are produced in the following chemical reaction, 43
kcal of heat energy is “absorbed.”
N2(g) + O2(g) → 2 NO(g), AH = +43 kcal
How much heat (in kJ) is exchanged when 152 g of NO(g) is produced?
