DescriptionVocab Word
chemical changes in which two or more substances react to form a single new substance, also called a synthesis reaction
any reactant that is used up first in a chemical reaction; it determines the amount of product that can be formed in the reaction
a reagent present in a quantity that is more than sufficent to react with a limiting reagent; any reactant that remains after the limiting reagent is used up in a chemical reaction
the amount of product that forms when a reaction is carried out in a labratory
chemical changes in which an element or compound reacts with oxygen; often producing energy as heat or light
a process that involves a complete or partial gain of electrons or a loss of oxygen
the amount of a product that could form during a reaction calculated from a balanced chemical equation; it represents the maximum amount of product that could be formed form a give
equations that show dissolved ionic compounds as dissociated free ions
chemical change that involves an exchange of positive ions between two compounds
another name for an oxidation reduction reaction
A method of balancing a redox equation by comparing the increases and decreases in its degree of oxidation or reduction
chemical equations that do not indicate the relative amounts of reactants and products
Equation showing either the oxidation or the reduction that takes place in a redox reaction
the substance in a redox reaction that donates electrons
A method of balancing redox equations by balancing the oxidation and reduction half-redution separately before combining them
ions that are not directly involved in a chemical reaction; an ion that doesn't change oxidation number or composition during a reaction
DescriptionVocab Word
A reaction that involves the transfer of electrons between reactants
chemical change in which one element replaces a second element in a compound; also called a displacement reaction
Chemical equations in which mass is conserved, each side of the equation has the same number of atoms of each element
the ratio of the actual yield to the theoretical yield for a chemical reaction expressed as a perentage; a measure of the efficency of a reaction
a conservation factor derived from the coefficents of a balanced chemical equation interpreted in terms of moles
equations for a reaction in solutions showing only those particles that are directly involved in the chemical change
an expression representing a chemical reaction, the formulas of the reactants are connected by an arrow with the formulas for the products
A process that includes complete or partial loss of elections or a gain of oxygen
A positive or negitive number assigned to an atom to indicate its degree of oxidation or redution
