Question

Which of the following correctly describes the law of conservation of matter?

Group of answer choices

A.) Matter can only be created, but not destroyed in chemical equations

B.) Matter can neither be created nor destroyed during a chemical reaction

C.) Matter can be destroyed during a chemical reaction as long as it is created again in a different reaction

D.) Matter makes up 98% of stuff in the universe, so it has to be created and destroyed sometimes

Answer 1

The law of conservation of matter indicates that matter cannot be created or destroyed in a chemical reaction, instead, it is conserved and only changes form. So the correct option is B

Step-by-step explanation:

The correct description of the law of conservation of matter is that matter can neither be created nor destroyed during a chemical reaction. This principle is foundational to the science of chemistry and implies that the amount of matter remains constant in a closed system, even as substances change form through chemical reactions.

Option B correctly states this principle: Matter can neither be created nor destroyed during a chemical reaction. This means that in any chemical equation, the same number of atoms for each element must be present in both the reactants and the products, ensuring mass is conserved.

For example, in a simple reaction where hydrogen gas reacts with oxygen to produce water (2H2 + O2 -> 2H2O), the total mass of hydrogen and oxygen before the reaction will equal the total mass of the water produced after the reaction. This illustrates that, under the law of conservation of mass, matter simply changes form and is neither gained nor lost.
