Single Replacement Reactions
Definition: 1 element switches places with another in a compound.
General Equation for a SingleReplacement Reaction:
A + BC > B + AC
Example of a SingleReplacement Reaction:
Cu + 2AgNO3 > Cu(NO3)2 + 2Ag
Copper (Cu) replaced silver (Ag)

DoubleReplacement Reactions
Definition: compounds exchange ions to form 2 new compounds
General Equation for a DoubleReplacement Reaction:
AB + CD > AD + CB
Example of a DoubleReplacement Reaction:
CaCO3 + 2HCl > CaCl2 + H2CO3
Calcium and hydrogen switch places.

OxidationReduction Reactions
Definition: reactions in which electrons are transferred from one reactant to another.
Oxidation: when an atom loses an electron
Reduction: when an atom gains an electron
*Oxidation and reduction always occur together!
Example of an OxidationReduction reaction:
2Ca + O2 > 2Ca2+O2
Which atom has been oxidized?
Which atom has been reduced?

a type of chemical process typified by the exchange of one or more hydrogen ions, H+, between species that may be neutral (molecules, such as water, H2O; or acetic acid, CH3CO2H) or electrically charged (ions, such as ammonium, NH4+; hydroxide, OH−; or carbonate, CO2/3−).
