Question: What is the definition of Stoichiometry?
Answer: ✔✔ The quantitative relationship and mathematical calculations between
reactants and products in a chemical reaction.
Question: What does the term "Theoretical Yield" mean?
Answer: ✔✔ The maximum quantity of product that can be generated by a
chemical reaction, determined mathematically from a balanced chemical equation.
Question: How do you calculate the Percent Yield (% Yield)?
Answer: % Yield -ANSWER ✔✔actual/theoretical x 100
Question: What is a Limiting Reactant?
Answer: ✔✔ The starting material that is completely consumed first during a
reaction, which determines the maximum amount of product that can be formed.
Question: What is an Excess Reactant?
Answer: ✔✔ The starting material that is not completely used up, leaving a
leftover portion once the chemical reaction concludes.
Question: What is the relationship between a Homogeneous Mixture and a
solution?
, Answer: ✔✔ A solution is a specific type of uniform, well-mixed homogeneous
mixture.
Question: In a chemical solution, what is the definition of a Solute?
Answer: ✔✔ The substance that is dissolved into another substance, meaning it is
present in the smaller amount.
Solvent -ANSWER ✔✔In a solution, there's more ___.
does not change -ANSWER ✔✔In dilution, the amount of solute ___.
changes -ANSWER ✔✔In dilution, the volume of the solution ___.
nonpolar -ANSWER ✔✔Nonpolar solutes dissolve best in ___ solvents.
polar -ANSWER ✔✔Polar and ionic solutes dissolve best in ___ solvents.
Aqueous Solutions -ANSWER ✔✔Solutions in which water is the solvent.
Strong electrolyte -ANSWER ✔✔This ionizes 100%.
Weak electrolyte -ANSWER ✔✔This does not ionize completely.
Nonelectrolyte -ANSWER ✔✔Produces no ions.
