Write the balanced equation for the reaction of hydrogen chloride with sodium hydrogen carbonate to give sodium chloride, carbon dioxide, and water.

These are the formulas of each compound mentioned:

1) Hydrogen chloride: HCl

2) Sodium hydrogen carbonate: NaHCO3 , this is also known as sodium bicarbonate. The number 3 to the right of O is a subscript.

3) Sodium chloride: NaCl

4) Carbon dioxide: CO2. This is also known as carbon anhydride. The number 2 to the right of O is a subscript.

5) Water: H2O. The number 2 to the right of H is a subscript.

The the chemical equation is:

HCl + NaHCO3 → NaCl + CO2 + H2O

Check the balance

element      left side      right side
H                 1+1 = 2        2
Cl                1                 1
Na               1                 1
C                 1                 1
O                 3                 2+1 = 3

Then, given that the number of each element on the left side is equal to the number of elements in the right side, the equation is balanced.

Hope you find the answer
