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.

Chemical change - chemical reaction.

Explanation:

Hello,

In this case, the presence of yeast in hydrogen peroxide promotes its decomposition as shown below:

Therefore, fizzing and bubbling is observed as well as a temperature increase due to an enthalpy change of -94.64 kJ/mol for this undergoing reaction, which accounts for an exothermic chemical reaction.

Best regards.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
