4Fe+3O₂⇒2Fe₂O₃

CO₂+2Cl₂⇒O₂+CCl₄

<h3>Further explanation  </h3>

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  

2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  

3. Select the coefficient of the substance with the most complex chemical formula equal to 1  

For simple equations, you can experiment with the balance of the number of atoms on the left and right

4Fe+3O₂⇒2Fe₂O₃

CO₂+2Cl₂⇒O₂+CCl₄

  • with variable :

aFe+bO₂⇒Fe₂O₃

Fe , left=a, right=2⇒a=2

O, left=2b, right=3⇒2b=3⇒b=3/2

the equation :

2Fe+3/2O₂⇒Fe₂O₃   x2

4Fe+3O₂⇒2Fe₂O₃

aCO₂+bCl₂⇒O₂+CCl₄

C, left=a, right=1⇒a=1

Cl, left=2b, right=4⇒b=2

O, left=2a, right=2⇒2a=2⇒a=1

the equation :

CO₂+2Cl₂⇒O₂+CCl₄
