Question

1. when 2.4g of magnesium reacts with 5.6g of oxygen, 8g of magnesium oxide is produced. which law is demonstrated by these masses? (1 pt)

Explanation:

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Here, the mass of reactants ($2.4g$ magnesium + $5.6g$ oxygen = $8g$) is equal to the mass of the product ($8g$ magnesium oxide).

Answer:

The law of conservation of mass.
