Answer 2

In a chemical reaction, energy may be gained or lost but the atoms stay the same - True

• During a chemical reaction, changes in chemical bonds occur.
• These changes involve energy transformations but the atoms remain the same.
• If energy is gained during the reaction, it is an endothermic reaction while if energy is lost, it is an exothermic reaction.
• There are many laws that govern these changes.
• Hence, the given statement is true.
