Help me solve this questions I've sent for chemistry

The reactants are sodium carbonate ($\text{Na}_2\text{CO}_3$) and hydrochloric acid ($\text{HCl}$).
The products of the reaction between a carbonate and an acid are a salt, water, and carbon dioxide. In this case, the salt formed is sodium chloride ($\text{NaCl}$).

• Balance sodium (Na): There are 2 Na atoms on the left, so place a coefficient of 2 in front of $\text{NaCl}$ on the right.

• Balance chlorine (Cl): Now there are 2 Cl atoms on the right, so place a coefficient of 2 in front of $\text{HCl}$ on the left.

• Check hydrogen (H), carbon (C), and oxygen (O):
  • H: 2 atoms on the left (from $2\text{HCl}$) and 2 atoms on the right (from $\text{H}_2\text{O}$). Balanced.
  • C: 1 atom on the left (from $\text{Na}_2\text{CO}_3$) and 1 atom on the right (from $\text{CO}_2$). Balanced.
  • O: 3 atoms on the left (from $\text{Na}_2\text{CO}_3$) and 1 atom (from $\text{H}_2\text{O}$) + 2 atoms (from $\text{CO}_2$) = 3 atoms on the right. Balanced.

The balanced chemical equation is:
