In a chemical reaction, we have two main parts: reactants and products.

Let’s break it down:

• Reactants: These are the ingredients we begin with. You can find them on the left side of the equation.
• Products: These are what we get after the reaction. They are shown on the right side.

For instance, in the reaction $2H_2 + O_2 \rightarrow 2H_2O$, hydrogen and oxygen are our reactants. The product we end up with is water.
