How much heat is produced when 4 moles N2 react?
N2+ 3H2 → 2NH3 +22 kcal

88 kcal of heat is produced by 4 moles of N₂

Explanation:

Given:

N₂ + 3H₂ → 2NH₃ +22 kcal

According to the reaction given, 1 mole of N₂ reacts with 3 moles of H₂ to release 22kcal of heat

If 4 moles of N₂ is taken then the amount of heat formed will be = 4 X 22 kcal

                                                                                                           = 88 kcal

Therefore, 88 kcal of heat is produced by 4 moles of N₂

i dont know

explanation:

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
