Question

$I$. The energy content of reactants in a chemical reaction must be equal to the energy content of the products.
$II$. Energy is conserved in chemical processes.

• A. Statement $I$ is true, Statement $II$ is true and is a correct explanation of the phenomena described in $I$
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false

Answer 1

The correct option is A Statement $I$ is true, Statement $II$ is true and is a correct explanation of the phenomena described in $I$

According to law of conservation of energy, energy can neither be created, nor be destroyed, it can be changed from one form to another.

Therefore, energy is conserved in a chemical change/processes, i.e; the energy content of reactants in a chemical reaction must be equal to energy content of the products.
