When baking soda (NaHCO_3) and vinegar (acetic acid, CH_3COOH) react, which of the following is a product of the reaction?

• A. Ammonia gas (NH_3)
• B. Sodium metal (Na)
• C. Carbon dioxide gas (CO_2)
• D. Hydrogen gas (H_2)

Answer: (C)

Verified step by step guidance

1. Identify the reactants: baking soda (NaHCO\_3) and vinegar (acetic acid, CH\_3COOH).
2. Recall that baking soda is a bicarbonate salt and reacts with acids to produce carbon dioxide gas, water, and a salt.
3. Write the balanced chemical equation for the reaction: \(\mathrm{NaHCO\_3 + CH\_3COOH \rightarrow CH\_3COONa + CO\_2 + H\_2O}\)
4. From the equation, observe that carbon dioxide gas (CO\_2) is released as a product of the reaction.
5. Understand that ammonia gas (NH\_3), sodium metal (Na), and hydrogen gas (H\_2) are not products of this acid-base reaction.
