To answer the questions,
(1) Activation energy is the amount of energy that is needed for the reaction to proceed, converting the reactant to products. The answer is letter B.
(2) The rate of chemical reaction normally increases as the reactant concentration is increased. The answer is letter C.
Stoichiometry measures any quantitative relationships and is used to determine the amount of products or reactants that are produced in a given reaction.
(Is that how you spell Stoichiometry)
Answer:
Explanation:
X + Y ⟶ XY
mass: 22.7 g x 86.9 g
According to the Law of Conservation of Mass, the mass of the product must equal the mass of the reactants.
