product
|
substance produced by a chemical reaction
|
|
reactant
|
substance that enters into a chemical reaction
|
|
chemical reaction
|
process in which substances undergo physical and chemical changes that result in the formation of new substances with different properties
|
|
endothermic
|
chemical reaction in which energy is absorbed
|
|
exothermic
|
chemical reaction in which energy is released
|
|
kinetics
|
study of rates of chemical reactions
|
|
collision theory
|
theory that relates collisions among particles to reaction rate: reaction rate depends on such factors as concentration, surface are, temperature, and catalysts
|
|
conservation of mass
|
mass of reactants is equal to the mass of the products in every chemical reaction. usually mass lost is from human error or leaking
|
|
reaction rate
|
measure of how quickly reactants change into products
|
|
acid
|
compound with a pH below 7 that tastes sour, turns blue litmus paper red, reacts with metals to produce hydrogen gas, and ionizes in water to produce hydrogen ions: proton donor
|
|
bases
|
compound with pH above 7 that tastes bitter, is slippery to the touch, turns red litmus paper blue
|
|
salt
|
compound formed from the positive ion of a base and the negative ion of an acid
|
|
precipitate
|
insoluble substance that crystalizes out of a solution
|
|
catalyst
|
substance that increases the rate of a reaction without being changed by the reaction
|
|
pH scale
|
measure of the hydronium ion concentration of a solution; measured on a scale from 0 to 14
|
|
activation energy
|
energy required for a chemical reaction to occur
