Steps for balancing an equation:

Lets take for the example

  1. Put boxes around the formulae.

  2. Create a table depicting the no. of atoms of each element in LHS and RHS. For example:

    ElementLHSRHS
    Fe13
    H22
    O14
  3. Choose the compound with max number of atoms in it, and choose the element which has the max number of atoms in LHS and RHS. For example here, and Oxygen.

  4. Multiply the smaller value of either side with a whole number to make it the same like the bigger value, like making a common denominator. For example,

    Atoms of OxygenLHSRHS
    Initial1 in 4 in
    Balance1 x 44
  5. Repeat the steps until the balance is complete and all the elements have same no. of atoms in each side. For example, the above equation will turn into,
