a condensed statement that used chemical formulas and identifies the reactants and products of a chemical reaction

process in which one or more substances are converted into new substances with different chemical and physical properties

a whole number that precedes a reactant or product symbol or formula in a chemical equation and indicates the relative number or representative particles involved in the reaction

a chemical reaction in which a hydrocarbon reacts with oxygen to produce carbon dioxide, water, and energy in the form of heat and/or light

matter is neither created nor destroyed

a chemical reaction in which a single complex compound is broken down into two or more products; general form is 

AB   yields   A  +  B

a chemical reaction in which the cations from two ionic compound replace each other forming two new ionic compounds; the general form is    AB  +  CD   yields   AD + CB

a chemical reaction between an acid and a base that destroys the chemical and physical properties of both; the products are water and a salt formed from the cation of a base and the anion of an acid

a chemical reaction in which a single element displaces another element that is part of a compound; general form is

A  +  BC    yields    B  +  AC

a chemical reaction in which two or more elements or compound combine to form a single product; general form is

A  +  B    yields    AB

How many atoms in all are in a molecule of serotonin?

What is a substance that speeds up the rate of a chemical reaction?

radioactive decay in which an atomic radius emits an alpha particle (helium nuclei) and a stable isotope; the stable isotope can be identified by subtracting 4 from the mass number of the radioactive isotope and subtracting 2 from its mass number

A french nobleman and chemist who had a big affection for the histories of chemistry and biology; developed the law of conservation of mass/matter

a type of radioactive decay that does not emit charged particles; it emits a high energy form of electromagnetic called a gamma ray photon

a reaction where the identity or characteristics of an atomic nucleus changes when it is bombarded with an energetic particle, such as in fission of radioactive decay

Which of the following are examples of an Exothermic Reaction?
