in the lab, mixing the sodium bicarbonate and acetic acid forms a _______ which is why the pressure in the
bottle_________.

• gas, increases
• gas, decreases
• liquid, increases
• liquid, decreases

Explanation:

When sodium bicarbonate ($NaHCO_3$) reacts with acetic acid ($CH_3COOH$), the chemical reaction produces carbon dioxide ($CO_2$) gas, along with sodium acetate and water. The production of this additional gas in a closed bottle increases the amount of gas molecules inside, leading to a rise in pressure within the container.

Answer:

gas, increases
