Answer 1

Correct answer is (c) An equal number of molecules on both the side

For explanation: A balanced reaction may not have an equal number of molecules on both the sides, because molecules may combine into one or a single molecule may breakdown into two or more. IT can disassociate or undergo double decomposition.
