Question

multiple choice 2 points
if 10g of reactants produce 10g of products, what principle is demonstrated?
law of conservation of mass
law of multiple proportions
law of definite composition
law of gravity

Explanation:

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Here, the mass of reactants (10g) equals the mass of products (10g), which aligns with this law. The law of multiple proportions is about elements combining in multiple ratios. The law of definite composition is about a compound having a fixed proportion of elements. The law of gravity is a physical law about gravitational force, not related to mass in chemical reactions.

Answer:

Law of conservation of mass
