TYPES OF CHEMICAL REACTIONS

SYNTHESIS REACTION

Synthesis Reaction - two reactants combine to make a larger product

HCl(g) + NH3(g) NH4Cl(s)

DECOMPOSITION REACTIONDecomposition Reaction - a large molecule breaks down to form two or more simpler products

DECOMPOSITION REACTION

SINGLE DISPLACEMENTSingle Displacement - an element displaces another element in a compound, producing a new compound and a new product

Cu(s) + 2AgNO3(aq) Cu(NO3)2(aq) + 2Ag(s)

DOUBLE DISPLACEMENTDouble Displacement Reaction - elements in different compounds displace each other, producing two new compounds

AgNO3(aq) + NaCl(aq) Na(NO3)(aq) + AgCl(s)

COMBUSTION REACTIONCombustion Reaction - rapid reaction of a substance with oxygen to produce oxides and energy; burning

Hydrocarbon - compounds that contain only hydrogen and carbon

Hydrocarbons often react with oxygen in combustion reactionsEnergy source for vehicles etc...

COMPLETE COMBUSTIONComplete Combustion - a combustion reaction of hydrocarbons that uses all the available fuel and produces only carbon dioxide, water, and energy ; occurs when oxygen supply is plentiful

i.e. CH4(g) + 2O2(g) --> CO2(g) + 2H20(g) + energy

INCOMPLETE COMBUSTIONIncomplete Combustion - a combustion reaction of hydrocarbons that may produce carbon monoxide, carbon (soot), carbon dioxide, water, and energy; occurs when oxygen supply is limited

i.e. C4H10 + 5O2(g) --> 2CO2(g) + 5H2O + CO + C(s) + energy
