Balanced:

2NaOH + CO2 → Na₂CO₃ + H₂O

Explanation:

To balance an equation, the amount of atoms on each side must be equal.

Atom Count on Reactant Side:

  • Na = 1
  • O = 3
  • H = 1
  • C = 1

Atom Count On Product Side:

  • Na = 2
  • C = 1
  • O = 4
  • H = 2

As you see, to simply balance the equation, put the 2 in order for the atom count on the reactant side to be equal to the product side. The 2 will add one more of each atom so that its the same as the product side.
