The substance that forms during a reaction and is found on the right side of the arrow in a chemical reaction is called a product.

Here's a simple breakdown:

* Reactants: The substances that go into a chemical reaction (found on the left side of the arrow).

* Products: The substances that are formed by the chemical reaction (found on the right side of the arrow).

For example, in the reaction:

H₂ + O₂ → H₂O

* Reactants: Hydrogen (H₂) and Oxygen (O₂)

* Product: Water (H₂O)
