The statement "matter can be neither created nor destroyed by chemical means, but it can be changed from one form to another" is the chemical law of


A. definite proportions.
B. atomic disintegration.
C. conservation of energy.
D. conservation of matter.
im not sure if its c or d but im leaning towards d since the question mentions matter, not energy

You are absolutely right and for that very reason.

thank you i wasn't sure :)

The correct answer is D. conservation of matter. The statement in the question reflects the law of conservation of matter, which states that during a chemical reaction, matter is neither created nor destroyed but can be changed from one form to another. The conservation of energy, mentioned in option C, is a different concept that relates to the principle that energy cannot be created or destroyed but can be converted from one form to another.

You are correct in leaning towards option D, conservation of matter. To confirm your answer, let me explain how to arrive at the correct choice.

The statement you mentioned, "matter can be neither created nor destroyed by chemical means, but it can be changed from one form to another," reflects the fundamental concept of the conservation of matter, often referred to as the law of conservation of mass in chemistry.

This law states that in any chemical reaction, the total mass of the substances involved remains constant before and after the reaction. This means that the number and type of atoms present in the reactants must be equal to the number and type of atoms in the products.

On the other hand, option C, conservation of energy, refers to the principle that energy cannot be created or destroyed, but can only be converted from one form to another. While conservation of energy is a significant principle, it is not directly related to the statement concerning the conservation of matter, as you correctly noted.

Therefore, based on the given information, the correct choice is D, conservation of matter.
