| Question | Answer |
| chemical reaction | produces new substances by changing how atoms are arranged |
| reactants | substances present when a chemical reaction starts |
| products | substances formed (produced) by a chemical reaction |
| catalyst | substance that speeds up a chemical reaction but is not consumed in the reaction |
| coefficient | the number of molecules of a substance in a chemical reaction |
| law of conservation of mass | atoms are not created or destroyed by chemical reactions |
| The CPGT Indications of a Chemical Reaction | *Color change *formation of a Precipitate (solid product) *formation of a Gas *Temperature change |
| synthesis reaction | new compound is formed from the combination of simpler reactants: A + B ---> AB |
| decomposition reaction | reactant breaks down into simpler products: AB ---> A + B |
| combustion | chemical reaction in which a substance reacts with oxygen, usually with the rapid release of heat and the production of a flame, such as the burning of methane gas |
| single replacement reaction | during a chemical reaction, one element replaces another in a compound: A + BC ---> AC + B |
| double replacement reaction | during a chemical reaction, two elements replace each other in different compounds: AB + CD ---> AD + CB |
| endothermic reaction (Endo's AEDT!) | chemical reaction that Absorbs surrounding Energy producing a Decrease in Temperature of the reaction mixture: REACTANTS + ENERGY ---> PRODUCTS |
| exothermic reaction (Exo's REIT!) | chemical reaction that Releases Energy producing an Increase in Temperature of the reaction mixture: REACTANTS ---> PRODUCTS + ENERGY |
| The CSTC Factors that Affect the Rate of Chemical Reactions | *Concentration *Surface size *Temperature *Catalyst |
| brilliant | what you are :) |
| activation energy | the minimum amount of energy needed to start a chemical reaction |
