Select the correct answer. which law represents a balanced chemical equation? a. avogadro’s hypothesis b. ideal gas law c. law of conservation of mass d. newton’s first law of motion e. newton’s second law of motion

Answer;

C. law of conservation of mass

Explanation;

The law of conservation of mass, which is one of the basic laws of chemical combination. This law states that during a chemical reaction, the total mass of the products remains equal to the total mass of the reactants.

Balanced chemical equations must obey the Law of Conservation of Mass that states that matter cannot be created or destroyed, it is conserved. Atoms are never lost or gained in chemical reactions, they are rearranged. The mass of the reactants must equal the mass of the products.

c. law of conservation of mass

Explanation: PLATO USERS

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
