According to the law of conservation of energy, what will most likely happen in a closed system?
b. energy will be exchanged, but matter will not be exchanged.
c. energy will be created along with matter.
d. energy will be destroyed, but matter will not be destroyed.

Option (B) is the correct answer.

Explanation:

According to the law of mass of conservation, energy can neither be created nor it can be destroyed as it can only be transferred from one place to another.

Thus, in a closed system the matter cannot be exchanged as the system is closed but there can be transfer of energy from the system to the surrounding.

Thus, we can conclude that energy will be exchanged, but matter will not be exchanged.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
