Chemical Bonding and Equations - PS 4 - (copy)

PLEASE use your periodic table.

Take your time and work carefully.

Use scrap paper to complete crossing problems when determining chemical formulas.

NOTE: QUIA has difficulty displaying numbers in the subscript position - therefore on this assessment be careful to interpret chemical formulas based on the POSITION of numbers on chemical formulas - water would be represented as H2O - the 2 should be in the subscript position but will not appear that way. Do not mistake them for Coefficients such as the following 3H2O - this tells you that there are 3 molecules of water each composed of 2 atoms of hydrogen (H2) and one atom of oxygen(O). BE CAREFUL.
