How is activation energy represented on an energy diagram? Energy
Reactants
Products
Reaction Progress
O A. Activation energy is the final energy level of the product
molecules.
B. Activation energy is the distance from the reactants to the top of
the "hill."
O C. Activation energy is the distance from the top of the "hill" to the
products.
D. Activation energy is the starting energy level of the reactant
molecules.

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.
