2. Is the hydrogen peroxide and yeast chemical reaction an endothermic or exothermic reaction? Use data and observations
as evidence to support your answer.

It took energy to break the hydrogen peroxide apart and energy was released when the oxygen and water were formed. Since more energy was released in this reaction, the temperature went up. This reaction is called an exothermic reaction.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
