Answer 1

The reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) primarily involves an acid-base reaction. The other reaction that occurs simultaneously can be classified as a **decomposition reaction**, as the acid reacts with the bicarbonate to produce carbon dioxide gas, water, and sodium acetate. Therefore, the correct completion would be:

The reaction between baking soda and vinegar was two reactions, one was the acid-base reaction and the other was a **decomposition reaction**.
