Question

Choose the balanced chemical equation below that best represents the following reaction:

When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl).




NaCl + H2O → NaHCO3 +CO2 + HCl


CO2 +H2O + NaCl → NaHCO3 + HCl


NaHCO3 + HCl → CO2 + H2O + NaCl


HCl + NaCl + H2O → NaHCO3 +CO2

Answer 1

The balanced chemical equation :

NaHCO₃ + HCl → CO₂ + H₂O + NaCl

Further explanation

A balanced chemical reaction shows that the number of atoms of the reactant and the number of atoms of the product is the same

When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl) .

This statement shows that

Reactants (located to the left of the reaction)

Baking soda (NaHCO₃) and Hydrochloric acid (HCl)

product (located to the right of the reaction)

Carbon dioxide(CO₂),water (H₂O) and Sodium chloride (NaCl).

So the reaction :

NaHCO₃ + HCl → CO₂ + H₂O + NaCl
