Brainliesttt ! during an experiment a thermometer was placed in a beaker containing hydrogen peroxide. the following observations were recorded when yeast granules were added to hydrogen peroxide. observation 1: fizzing and bubbling took place. observation 2: the temperature began to rise. based on the observation, justify the type of change (physical or chemical) that took place.

While I am not the brainliest I can certainly answer.  

This was a chemical change because the chemical components were changed, a big giveaway to this was the fizzing, however the temperature rising was also another giveaway.

Explanation:

A physical change is the change that does not bring any difference in the chemical properties of a substance.

For example, change in shape, size, state, mass, density etc are all physical changes.

On the other hand, a chemical change is define as the one which brings difference in chemical composition of a substance.

For example, yeast granules were added to hydrogen peroxide then fizzing and bubbling took place. This means that a chemical reaction has taken place due to which a gas is liberating out of the solution.

Also, heat is liberating due to which temperature has began to rise.

Thus, we can conclude that based on the given observation a chemical change has taken place.

the answer is a and have a great day
