Answer:
Energy released as heat will be -189.417 Kj
Explanation:
The oxidation is the type of reaction in which reaction occurs in the presence of oxygen. The exothermic reaction is the type of reaction in which heat is released. The enthalpy is the type of physical quantity that is used to measure the energy in the thermodynamic system.
As we know the molar mass of Copper II Oxide is 79.545 g
Also the oxidation of copper(II) oxide, CuO(s), is an exothermic process, 2Cu2O (s) + O2-->4CuO (s) delta H reaction= -292.0 kj/mol.
So for 51.60g of Copper II Oxide,
Heat released will be (-292.0 * 51.60/79.545) = -189.417 Kj
