CHEM TEST !!
| Question | Answer |
|---|---|
| Stoicometry | the calculations of quantities in a chemical reaction |
| Law of conservation of mass: | in any chemical reaction, the mass of the products is always equal to the mass of the reactants |
| Mole ratio: | a conversion factor derived from the coefficients of a balance chemical equation interpreted in terms of moles |
| Limiting reagent | the reactant that determines the amount of product that can be formed |
| Excess reagent: | any reactant that is not used up in a reaction |
| Theoretical yield: | the amount of product that could form during a reaction calculated from a balanced chemical equation; it represents the maximum amount of product that; it represents the maximum amount of product that could be formed from a given amount of reactant |
| Actual yield: | the amount of product that forms when a reaction is carried out in the laboratory |
| Percent yield: | the ratio of the actual yield to the theoretical yield for a chemical reaction expressed as a percentage; a measure of the efficiency of a reaction |
