Review balancing equations

Review: Balancing Equations

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.


Electronegativity review

Electronegativity Review

  • Non-polar covalent x<.5 (shares equally)

  • Polar covalent .5<x<1.5 (shares unequally)

  • Ionic x>1.5 (give-take relationship)
