Answer:

The answer would most likely be C 22 grams.

Explanation:

I did a small science experiment when I was in high school with mold and it did increase the weight of whatever food I was using but not that significant so I think it would be 22 grams.

in a chemical change how does the total energy of the reactants compare to the total energy of the products
jeka57 [31]

Answer:

Explanation:

All chemical changes requires a substantial amount of energy. Depending on the type of reaction, the energy of reactants and products differs.

In an exothermic chemical change where heat is always given off to the surroundings, the energy of the product is less than that of reactants.

For endothermic changes, the surrounding becomes colder at the end of the reaction. This implies that the heat energy of the product is higher than that of the reactants.
