The little numbers which are on the bottom right show the amount of times an atom is there.

Answer:

Explanation:

Reactants are written on the left hand side of a chemical equation.

In this case, they are Fe2O3 + 3H2

Counting the numbers:

There are 2 Fe (iron) atoms.

There are 3 O (oxygen) atoms.

For Hydrogen, it is a gas with 2 H atoms per molecule. So you need to multiple 3 by 2:

There are 6 H (hydrogen) atoms.
