Chemical Reactions


Balance chemaical reaction both sides of the equation have same number of atoms of each element
Correct Amounts the amount of reactants to predict the amounts or products
Coefficients the numbers which represent the number of units of each substance an reaction
Chemical equation is using chemical formules ans symbols to describe a chemical reaction and the products it produces
Antoine Lavoiser experimented with mercury 2 oxide and heat
Products new substances that are produce
Chemical Reactions Change of one or more substance converted into new sub substances
Synthesis Reaction A + D -> C two or more sunstance form new substance
Single Replacement A + BC -> AC + B or D -> BC + C one element replaces another one is a compound
Double Replacement AB + CD -> AD + CD results if a precipitate water or a gas forms when two ionic compounds in solution are combined
Exotherermic reaction energy given off in the form of heat
Exergonic Recation energy required to break bonds is less than the energy released from new bonds energy given off usuallly light
Endergonic Reactions more energy is required to break bond than to form new ones need energy for the reaction to occur
Endothermic reaction energy needed is heat
Catalyst is a substance that speeds up a chemical reactions without being permanently changed
inhibitors prevents or slows a chemical reaction or interferes with a catalysts action
