Question

baking soda and vinegar a chemical change or physical change?

Answer 1

Is this an example of an exothermic reaction or an endothermic reaction? Hint: how did the temperature of the vinegar before the experiment compare to the vinegar after the experiment?(1 point)
Responses

Exothermic
Exothermic

Endothermic

Answer 2

When baking soda and vinegar are combined, a chemical reaction occurs. This reaction is a chemical change as new substances with different properties are formed. Baking soda (sodium bicarbonate) reacts with vinegar (acetic acid) to produce carbon dioxide gas, water, and a salt called sodium acetate.

Answer 3

This is an exothermic reaction. The temperature of the vinegar before the experiment is usually lower than the temperature after the reaction.
