identify the number of atoms on the reactant side of the chemical equation. fe₂o₃ + 3h₂ → 2fe + 3h₂o there are fe (iron) atoms. there are o (oxygen) atoms. there are h (hydrogen) atoms.

identify the number of atoms on the reactant side of the chemical equation. fe₂o₃ + 3h₂ → 2fe + 3h₂o there are fe (iron) atoms. there are o (oxygen) atoms. there are h (hydrogen) atoms.

Answer

Explanation:

Step1: Count Fe atoms

In $Fe_2O_3$, the sub - script of Fe is 2. There are no other Fe sources on the reactant side. So the number of Fe atoms is 2.

Step2: Count O atoms

In $Fe_2O_3$, the sub - script of O is 3. There are no other O sources on the reactant side. So the number of O atoms is 3.

Step3: Count H atoms

In $3H_2$, the coefficient 3 multiplies the sub - script 2 of H. So the number of H atoms is $3\times2 = 6$.

Answer:

There are 2 Fe (iron) atoms. There are 3 O (oxygen) atoms. There are 6 H (hydrogen) atoms.
