front 1 alpha radioactive decay | back 1 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 Word |
front 2 Antoine Lavoisier | back 2 A French nobleman and chemist who had a big affection the histories of chemistry and biology; developed the Law of Conservation of Mass/Matter |
front 3 balanced chemical equation | back 3 chemical equation that uses coefficients to show that the number of atoms of each element that enters into a reaction is equal to the number of atoms of that same element produced during the reaction |
front 4 beta radioactive decay | back 4 radioactive decay in which an atomic radius emits a beta particle (electron) and a stable isotope; the stable isotope can be identified by subtracting 2 from the atomics number of the radioactive isotope while the mass number is unchanged |
front 5 chemical equation | back 5 a condensed statement that used chemical formulas and identifies the reactants and products of a chemical reaction |
front 6 chemical reaction | back 6 process in which one or more substances are converted into new substances with different chemical and physical properties |
front 7 coefficient | back 7 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 |
front 8 combustion reaction | back 8 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 |
front 9 gamma radioactive decay | back 9 a type of radioactive decay that does not emit charged particles; it emits a high energy form of electromagnetic called a gamma ray photon |
front 10 law of conservation of matter/mass | back 10 matter is neither created nor destroyed; in a balanced chemical equation, the mass of all the atoms of all the elements present on the reactant and product side must be the same |
front 11 decomposition reaction | back 11 a chemical reaction in which a single complex compound is broken down into two or more products; general form is AB yields A + B |
front 12 double displacement reaction | back 12 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 |
front 13 neutralization reaction | back 13 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 |
front 14 nuclear reaction | back 14 a reaction where the identity or characteristics of an atomic nucleus changes when it is bombarded with an energetic particle, cush as in |
front 15 single displacement reaction | back 15 a chemical reaction in which a single element displaces another element that is part of a compound; general form is |
front 16 synthesis reaction | back 16 a chemical reaction in which two or more elements or compound combine to form a single product; general form is |
