Balancing Chemical Equations Calculator
Top

An equation is said to be balanced, if the number of atoms of an element on both sides of a chemical reaction is equal.

Balancing Chemical Equations Calculator (or Balancing Equations Calculator) is an online tool which is used to balance the equation when an unbalanced chemical equation is given. You just have to enter the equation of your choice by editing the default equation you will get the balanced equation.
Below is given a default equation you could see how balancing of equation is happening using this calculator.

 

Steps to Balance Chemical Equations

Back to Top
Step 1 :  

Convert the word equation into formula equation.



Step 2 :  

Note down the number of different atoms present on left hand side and right hand side of the equation.



Step 3 :  

Add coefficients to balance the equation, so that we have the equal number of atoms of each element on both the reactant(left hand side) and product(right hand side) of the equation.


Note: Remember that never change a formula to balance a chemical equation.

  1. Balance the chemical equation:  H2 + I2 -> HI


    Step 1 :  

    Given chemical equation:  H2 + I2 -> HI



    Step 2 :  

    Atoms on


    Reactants side                Products side


                   2---------I--------1


                   2--------H--------1



    Step 3 :  



    Reactants side                Products side


                  2---------I--------1 x 2 = 2


                  2--------H--------1 x 2 =2


    H2 + I2 -> 2 HI



    Answer  :  

    H2 + I2 -> 2 HI



  2. Balance the chemical equation: Mg + HCl -> MgCl2 + H2


    Step 1 :  

    Given chemical equation: Mg + HCl -> MgCl2 + H2



    Step 2 :  

    Atoms on


    Reactants side                Products side


                1---------Mg--------1


                1---------Cl---------2


                1---------H---------2



    Step 3 :  



    Reactants side                Products side


                 1---------Mg--------1


           2 x 1---------Cl---------2


           2 x 1---------H---------2


    Mg + 2HCl -> MgCl2 + H2



    Answer  :  

    Mg + 2HCl -> MgCl2 + H2
