oxidation reaction
when the reaction has gained oxygen
exothermic reaction
when energy stored in the reactants is transferred to the surroundings
endothermic reaction
when energy is transferred from the surroundings to the reactants
displacement reaction
a reaction occurs when a more reactive element displaces, or pushes out, a less reactive element from a compound that contains the less reactive element
ore
a rock that contains enough of a metal or metal compound to be worth mining
thermal decomposition
a chemical reaction that happens when a compound breaks down when heated
