Chapter 12; Stoichiometry: key ideas and concepts
| Question | Answer |
|---|---|
| How do chemists use balanced chemical equations? | Chemists use balanced chemiscal equations as a basis to calculate how much reactant is needed or how mush product will be formed in a reaction. |
| What is stoichiometry? | the calculations of quantities in chemical reactions |
| In terms of what quantities can you intercept a balanced chemical equation? | a balanced chemical equation can be intercepted in terms of different quantities , including number of atoms, molecules or moles mass or volume. |
| What is a mole ratio? | a conversion factor derived from the coefficients of a balanced chemiscal equation (interpreted in terms of moles) |
| How are mole ratios used in chemical calculations? | they are used tp convert between a given number of moles of a reactant or product to moles of a different reactant or product. |
| What are the three steps in solving a stoichiometry problem? | 1) convert to moles 2) find the mole ratio 3) convert to something else |
| Limiting reagent: | the reactant that determines the amount of product that can be formed by a reaction. |
| Excess reagent: | the reactant that is not completely used up in a reaction. |
| Theoretical yield: | the maximum amount of product that can be formed from given amounts of reactants. |
| Actual yield: | the amount of product that actually forms when the reaction is carried out. |
| Percent yield: | the ratio of the actual yield to the theoretical yield expressed as a percent. |
