Chapter 5: Classification and Balancing of Chemical Reactions Flashcards
chemical equation
an expression in which symbols and formulas are used to represent a chemical reaction
reactant
a substance that undergoes change in a chemical reaction
product
a substance that is formed ina chemical reaction
balanced equation
a chemical equation in which the numbers and kinds of atoms are the same on both sides of the reaction
coefficient
a number placed in front of a formula to balance a chemical equation
law of conservation of mass
matter is neither created nor destroyed
precipitate
an insoluble solid that forms in solution during a chemical reaction
salt
an ionic compound formed from the reaction of an acid with a base
redox reaction
a reaction in which electrons are transferred from one atom to another
solubility
the amount of a compound that will dissolve in a given amount of solvent at a given temperature
neutralization reaction
the reaction of an acid with a base
oxidation
the loss of one or more elections by an atom
reduction
the gain of one or more electrons by an atom
reducing agent
a reactant that causes a reduction in another reactant by giving up electrons to it
oxidizing agent
a reactant that causes an oxidation by taking electrons from another reactant
