Question: how much heat energy is liberated when 11.0 grams of manganese?
Answer: How much heat energy is liberated when 11.0 grams of manganese is converted to MNn_2O_3 at standard state conditions? Delta H^0_f NMin, 0, (t) is-962.3 kJ/mol 96.2 kJ 192 kJ 289 kJ 460 kJ 964 kJ When 32.1 g of H_2 reacts with excess silicon to form SiH_4(g) at standard conditions, 270.1 kJ of heat is absorbed.
