Which process below would be considered a chemical change?
a. mixing two cheeses in a bowl.
b. grating cheese.
c. molding of cheese.

C. Molding of cheese.

Explanation:

Hello,

In this case, both mixing and grating of cheese are physical changes as the composition of the cheese does not change. In contrast with the aforesaid options, molding of cheese is associated with the growing metabolic process of mold as it is chemically processing the cheese to both grow and produce other types of metabolites which are quite different than the initial cheese's components.

Best regards.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
