Chapter 8: Chemical Reactions Flashcards
A small whole number that appears in front of a formula in a chemical equation
Coefficient
a representation with symbols and formulas of the identities and relative amounts of the reactants and products in a chemical reaction
Chemical equation
A representation of the reactants and products of a chemical reaction by their symbols or formulas
Formula equation
A solid that is produced as a result of a chemical reaction in a solution and that separates from the solution
Precipitate
A chemical reaction in which the products reform the original reactants
Reversible reaction
An equation in which the reactants and products in a chemical reaction are presented by words
Word equation
A reaction in which a substance combines with oxygen, releasing a large amount of energy in the form of light and heat
Combustion reaction
A reaction in which two or more substances combined to form a new compound
Composition reaction
A reaction in which a single compound produces two or more simpler substances
Decomposition reaction
A reaction in which one element replaces a similar element in a compound
Displacement reaction
The ions of two compounds exchanged places in an aqueous solution to form to new compounds
Double replacement reaction
They decomposition of a substance by an electric current
Electrolysis
Same as displacement reaction
Single replacement reaction
Same as a composition reaction
Synthesis reaction
A list of elements organized according to the ease with which the elements undergo certain chemical reactions
Activity series
