Question

baking soda and vinegar can be used to model a volcanic eruption in a science demonstration because they bubble violently when mixed. what can be concluded about mixing vinegar and baking soda?
a. vinegar boils when it comes in contact with baking soda.
b. baking soda and vinegar make a uniform mixture.
c. baking soda has a lower density than vinegar.
d. vinegar and baking soda react to form a new gaseous substance.

Explanation:

The problem states baking soda and vinegar bubble violently when mixed. Bubbling indicates gas production, which is a sign of a chemical reaction forming a new gaseous substance. Option A is wrong because bubbling ≠ boiling; Option B is wrong as violent bubbling means non-uniform mixture; Option C is irrelevant (density not mentioned).

Answer:

D. Vinegar and baking soda react to form a new gaseous substance.
