Question

in atomic theory, new substances are formed when the atoms of other substances are rearranged and the number of atoms is conserved. an example of this is shown in the diagram below. there are six atoms both before and after. which statement below is also true of the rearrangement of atoms? a. the amount of matter decreases. b. the number of substances is conserved. c. the amount of matter is conserved. d. the number of substances increases.

Explanation:

According to the law of conservation of mass in chemistry, during a chemical reaction (atom - rearrangement), the amount of matter is conserved. The number of atoms is conserved as stated in the atomic theory, and this implies the conservation of matter. The number of substances can change during a reaction.

Answer:

C. The amount of matter is conserved.
