Answer 1

Answer:

Hey mate,

Your answers are as follows:

1) The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted.

2) The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass.  For example, in a nitrogen dioxide (NO2) molecule, the ratio of the number of nitrogen and oxygen atoms is 1:2 but the mass ratio is 14:32 (or 7:16).
