classifying chemical reactions

oxidation-reduction reactions (redox reaction)

(also called a redox reaction), one substance loses one or more electrons and another substance gains one or more electrons

organic compound

a compound that contains carbon and hydrogen (and, in some cases, oxygen or other elements as well

acid-base reactions (neutralization reaction)

an acid and a base react to form salt and water. An acid-base reaction is also called a neutralization reaction

salt

any ionic compound formed by the reaction of an acid and a base

double replacement reactions

he ions of two different compounds in an aqueous solution exchange places to form two new compounds. One of the products formed is typically a solid (or precipitate), a gas (bubbles), or water. The other product usually remains dissolved in the solution. The general form for a double-replacement reaction is shown below. AC + BD → AD + BC

combustion reactions

matter cannot be created nor destroyed during a chemical reaction. This statement is known as the law of conservation of mass

single replacement reactions

one element replaces another element in a compound to form a new substance. Single-replacement reactions have the same number of reactants as products. Replacement reactions are also called displacement reactions. The general form for a single-replacement reaction is shown below. A + BC → AC + B

decomposition reactions

one reactant breaks down to form two or more products. The general form for a decomposition reaction is shown below. AB → A + B

exothermic

release energy

reduction

the gain of electrons

oxidation

the loss of electrons

synthesis reactions

two or more reactants combine to form one new product. Chemists often use the following generic equation to represent a synthesis reaction: A + B → AB
