Question

1. apply concepts the law of conservation of mass was introduced in chapter 2. use daltons atomic theory to explain this law.

Explanation:

Dalton's atomic theory posits that atoms are indivisible and indestructible. In a chemical reaction, atoms are merely rearranged. Since atoms have a fixed mass, the total mass before and after a reaction remains the same, which explains the law of conservation of mass.

Answer:

Dalton's atomic theory explains the law of conservation of mass as atoms are rearranged in reactions without being created or destroyed, thus mass is conserved.
