Question

a student wants to create a liquid volcano. the student observes bubbles in the soft drink prior to opening it. the student first proceeds to open the soft drink bottle and place it on the floor. next the student drops candy tablets into the drink at a continuous pace. the student notices a very powerful reaction in which the candies, still intact, are pushed out of the soda as the drink fizzes and starts to bubble. in this scenario, what would be the catalyst?
○ the candy tablets being added to the drink.
○ the gasses being released when the drink was first opened.
○ the liquid in the container.
○ the container that holds the liquid.

Explanation:

A catalyst speeds up a reaction without being consumed. When candy tablets are added to the soft drink, they speed up the release of gas (fizzing/bubbling). The gas release when opening is part of the initial process, the liquid is the reactant medium, and the container doesn't act as a catalyst. So the candy tablets are the catalyst here.

Answer:

The candy tablets being added to the drink.
