Tim makes a volcano demonstration for a class. he crafts the volcano out of clay, and then pours vinegar into the baking soda that is inside the volcano. what would be the best way for tim to turn this demonstration into an experiment? a) he could pour the same amount of vinegar into several different volcanoes containing baking soda, repeating the demonstration. he would be answering the question “what happens when i pour vinegar into baking soda? ” b) he could time how long the volcano bubbles after he pours the vinegar into the baking soda. he would be answering the question “how long will my volcano bubble? ” c) he could measure how far the bubbles travel across the laboratory table after he pours the vinegar into the baking soda. he would be answering the question “how far will bubbles travel across a flat surface? ” d) he could add different amounts of vinegar to the same amount of baking soda and time how long it bubbles each time. he would be answering the question “how does increasing the amount of vinegar affect the amount of bubbles that form? ”

Option (D)

Explanation:

Baking soda contains bicarbonates and vinegar contains acetic acid. When acetic acid reacts with the bicarbonates it generates Carbon dioxide (CO₂) gas. Adding more quantity of vinegar into the same amount of baking soda will lead to the formation of bubbles for a longer period of time. So from this demonstration, Tim can perform an experiment where increasing the quantities of vinegar will lead to an increase in the number of bubbles and forming bubbles for a long time.

In nature, the volcanic eruptions take place because magma comes out to the surface forming lavas ejecting a significant amount of Carbon dioxide (CO₂) into the atmosphere. If the amount of intruding magma is high then it will lead to extensive volcanism thereby releasing a huge amount of carbon dioxide.

Thus, the correct answer is option (D).

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

the answer is c.
