Question

What is conserved during a chemical reaction matter, energy, both, or niether?

Answer 1

Both energy and matter are conserved during a chemical reaction.

Further Explanation:

Chemical reaction

It is the process to convert one or more substances into different substances. Reactants are the substances that experience changes during chemical reactions whereas products are formed once the reaction is complete. The properties of products are usually different from those of reactants.

Law of conservation of mass:

According to this law, the mass of an isolated system can neither be created nor be destroyed in a chemical reaction. In other words, the mass of reactants will always be equal to the mass of products. The quantity of matter in any material is known as mass. The conservation of matter also holds good for chemical reactions.

Law of conservation of energy:

It states that the energy can neither be created nor be destroyed but can only be converted from one form to another.

Therefore both matter and energy are conserved during a chemical reaction.

Answer 2

Answer: Option (c) is the correct answer.

Explanation:

According to the law of conservation of energy or matter, it is stated that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.

Same applies to the matter that matter can be transformed from one form to another.  

Thus, we can conclude that during a chemical reaction both matter and energy is conserved.
