Question

question 10 (1 point)
excerpt from a chemistry article: \chemical reactions involve the breaking and forming of bonds between atoms. the law of conservation of mass states that in any chemical reaction, mass is neither created nor destroyed.\
how does the concept of conservation of mass compare to the description of chemical reactions in the passage?
a both describe reactions that involve the creation of new substances.
b the law of conservation of mass contradicts the process of breaking and forming bonds.
c both describe processes that can change the nature of substances involved.
d the law of conservation of mass suggests that no mass is lost or gained in a reaction.

Explanation:

The law of conservation of mass states mass is conserved in chemical reactions, meaning no mass is created or destroyed. This aligns with the description in the passage. Options A and C do not directly address the conservation - of - mass concept. Option B is incorrect as the law does not contradict bond - breaking and forming.

Answer:

D. The law of conservation of mass suggests that no mass is lost or gained in a reaction.
