Q1. In a chemical reaction, matter is neither created nor destroyed. Which law does this refer to?

Background

Topic: Conservation of Mass

This question is testing your understanding of fundamental laws in chemistry, specifically the law that governs the behavior of matter during chemical reactions.

Key Terms:

• Law of Conservation of Mass: States that mass is neither created nor destroyed in a chemical reaction.

• Law of Definite Proportions: States that a chemical compound always contains the same elements in the same proportion by mass.

• Law of Multiple Proportions: States that when two elements combine to form more than one compound, the masses of one element that combine with a fixed mass of the other are in ratios of small whole numbers.

• Law of Indestructibility: Not a standard chemistry law, but sometimes used to refer to conservation principles.

Step-by-Step Guidance

1. Read the statement carefully: "matter is neither created nor destroyed." This is a fundamental principle in chemistry.

2. Recall the names and definitions of the major laws of chemistry related to matter and reactions.

3. Compare the statement to the definitions of the laws listed in the answer choices.

4. Identify which law specifically addresses the conservation of matter during chemical reactions.
