Answer:

2NaHCO₃ -----> Na₂CO₃ + CO₂ + H₂O

Explanation:

Look at all the compunds in the reaction and count each individual atom in the compounds. For example. there are 1 Na atom, 1 H atom, 1 C atom, and 3 O atoms.  

The left side of your reaction has:  

  • 1 Na
  • 1 H
  • 1 C
  • 3 O

The right side of the reaction has:

  • 2 Na
  • 2 H
  • 2 C
  • 6 O

Based on the amount of atoms on each equation, we can determine that a coeeficient needs to be placed on the NaHCO₃ compound. We should place a 2 next to the NaHCO₃ compound to balance the equation. By placing the 2 next to that compund, we must multipy the number of atoms of each element.

After multipying the 2 the atoms on the left have:

  • 2 Na
  • 2 H
  • 2 C
  • 6 O

Notice how the atoms on the left are now equal to the atoms on the right. The equation go from NaHCO₃ ----> Na₂CO₃ + CO₂ + H₂O to 2NaHCO₃ ----> Na₂CO₃ + CO₂ + H₂O
