Question

1 multiple choice 1 point which branch of chemistry deals with the mass relationships of elements in compounds and the mass relationships among reactants and products in chemical reactions? chemical kinetics entropy stoichiometry 2 multiple choice 1 point a balanced chemical equation allows one to determine the mechanism involved in the reaction. electron configuration of all elements in the reaction. mole ratio of any two substances in the reaction.

Explanation:

1. Stoichiometry focuses on mass relationships in compounds and chemical reactions. Chemical kinetics deals with reaction rates, and entropy is about disorder.
2. A balanced chemical equation shows mole ratios (coefficients). It doesn't show reaction mechanisms or electron configurations.

Answer:

1. C. stoichiometry
2. C. mole ratio of any two substances in the reaction
