Question

During a chemistry demonstration, a student added liquid hydrochloric acid, HCl, to a beaker holding powdered baking soda, NaHCO3. The solution in the beaker began to bubble and fizz as carbon dioxide gas, CO2, escaped. How did combining a liquid and a solid produce a gas? Group of answer choices The atoms in the hydrochloric acid and baking soda combined, forming a product with a different state but the same properties. Adding the hydrochloric acid to the baking soda superheated the hydrochloric acid, causing it to change phases The atoms in the hydrochloric acid and baking soda rearranged, forming products with different properties. Adding the hydrochloric acid to the baking soda superheated the baking soda, causing it to change phases.

Answer 1

The atoms in the hydrochloric acid and baking soda rearranged, forming products with different properties.

Step-by-step explanation:

Hello!

When you add hydrochloric acid to sodium bicarbonate (base) happens the following reaction:

HCl(aq) + NaHCO₃ ⇆ NaCl(aq) + H₂O + CO₂(g)

This is an acid-base reaction called neutralization, in wich salt (NaCl) and water (H₂O) plus a residue of carbon dioxide gas.

Hope you have a nice day!
