Term
|
Definition
| *Key Concept: A balanced chemical equation provides the same kind of quantitative information that a recipe does.* *Key Concept: Chemists use balanced chemical equations as a basis to calculate how much reactant is needed or product is formed in a reaction.* |
|
|
Term
| Stoichiometry (Not pronounced STOYK, because that makes you sound like an emu) |
|
Definition
| The calculaions of quantities in a chemical reaction using a balanced chemical equation. |
|
|
Term
| Interpreting Chemical Equations |
|
Definition
| *key Concept: A balanced chemical equation can be interpreted in terms of differant quantitues, including number of atoms, molecules or moles; mass or volume.* |
|
|
Term
|
Definition
| *Key Concept: mass and atoms are conserved in every chemical reaction.* |
|
|
Term
| Mole Ratio (Mol Rat (like the naked ones)) |
|
Definition
| A conversion factor derived from the coefficents in a balanced chemical equation interpreted in terms of moles. *Key Concept: In chemical calculations, moles are used to convert between moles of a reactant and/or moles of a product. |
|
|
Term
| Other Stoichiometry Equations |
|
Definition
| *Key Concept: In a typical stoichiometric problem, the given quantity is first converted to moles. Then the mole ratio from the balanced equation is used to calculate the number of moles of the wanted substance. Finally, the moles are converted to another unit of meaurement related to the mole, as the problem requires. |
|
|
Term
| Limiting and Excess Reagent |
|
Definition
| *Key Concept: In a chemical reaction, an insufficent quantity of any of the reactants will limit the amount of product that forms.* |
|
|
Term
|
Definition
| The reactant that determines the amount of product that can be formed by a reaction. |
|
|
Term
|
Definition
| The reacant not entirely used up by the reaction. |
|
|
Term
|
Definition
| The maximum amount of product that could be formed from given amounts of reactant. |
|
|
Term
|
Definition
| the amount of product formed from given amount of reactant when the reaction is carried out in a lab. |
|
|
Term
|
Definition
| The ration of actual yield to theoretical yield expressed as a percent. *Key Concept: The percent yield is a measure of efficency of a reaction carried ou in a lab.* |
