Substances initially present in a chemical reaction that are consumed during the reaction or a substance that participates in a chemical reaction, esp a substance that is present at the start of the reaction while the end product of some chemical reactions yield products.
A reactant is a substance that participates in and changes during a reaction.
A change that produces a new substance is called a chemical reaction. The substance initially involved in a chemical reaction are called reactants or reagents.
When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.
Anew substance that is formed is a product in a chemical reaction
Reactant

Answer:A physical reaction is a reaction whereby a new substance is not formed and is reversible.For example,folding of paper. Unlike a physical reaction,a chemical reaction is a process whereby a new substance is formed and is not reversible.For example,burning of paper.

A product is a substance that is formed by a chemical reaction.
This substance is called the end-product of a chemical reaction.
