Answer 1

If the powder is baking soda (sodium bicarbonate) and the student performs the vinegar test, they can expect that it will bubble and foam. This reaction occurs because baking soda reacts with the acetic acid in vinegar, producing carbon dioxide gas, which creates the bubbling effect. Therefore, the correct response is:

it will bubble and foam.
