Question

during a chemical reaction, the law of ______ ______ states that the total mass of the products must be equal to the total mass of the reactant. a multiple proportions b definite proportions c conservation of mass

Explanation:

• The 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 element are in ratios of small whole numbers.
• The law of definite proportions states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
• The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. So, the total mass of the products must be equal to the total mass of the reactants.

Answer:

C. Conservation of mass
