Question

draw an example showing reactants and products

Explanation:

A simple chemical reaction is chosen to clearly illustrate reactants (starting substances) and products (substances formed after the reaction). The reaction of hydrogen and oxygen forming water is a common, easy-to-visualize example.

Answer:

Here is a diagram of a reaction with labeled reactants and products:

Reactants               Products
2H₂(g) + O₂(g)   →   2H₂O(l)
[Hydrogen gas] + [Oxygen gas]   →   [Liquid water]

(Visual representation: You can draw two molecules of H₂ (each as two small circles bonded together) and one molecule of O₂ (two larger circles bonded together) on the left, an arrow pointing right, and two molecules of H₂O (each with one large circle bonded to two small circles) on the right, labeling the left side "Reactants" and the right side "Products".)
