Answer: The reaction 2CuO + 315 kJ → 2Cu + O2 is an endothermic reaction. (Option B)
Explanation: In order to determine what type of reaction is occurring above, you need to know that if heat is being released then it is an exothermic reaction. It can be determined if it would be on the product side. Whilst, if the heat is being absorbed, it would be an endothermic reaction and it would be on the side of the reactants.
No, the only way they can be separated is through chemical methods. ... A compound is made up of two or more elements that are chemically combined and elements are combined to form a compound.
