Write a chemical equation for

Reactants: Aluminum Oxide, Fluorine

Products: Aluminum Fluoride, Oxygen

Find the superscripts (ionization), subscripts (molecular stochiometry), and coefficients (balance the equation) in that order.

OCTOBER 20TH, 2010

Covalent BondsMetallic, Ionic, & Molecular Compounds

Superscripts:

Identify the ionization of each atom.

2) Subscripts:

Use the criss-cross method, least common multiple method, or the Lewis Dot Diagram method to find the stochiometry of the molecules.

Coefficients:

Multiply molecules by coefficients that make the left and right side of the equation equal. Do this systematically, atom type by atom type.

- Non-polar covalent x<.5 (shares equally)
- Polar covalent .5<x<1.5 (shares unequally)
- Ionic x>1.5 (give-take relationship)
