HW. do the take home quiz, we'll go over it next class. For some reason the scanner won't send me my scans so I don't have the extra worksheets to post hopefully tech can help me with it tomorrow. Please feel free to stop by anytime tomorrow for hard copies of extra practice and a corresponding key. Remember, Review next class and Test Monday/Tuesday.

UPDATE: the emails are slowly rolling in, keep checking back.

HW - Try to use the criss-cross method to write the formulas for the following ion combinations. Remember to write a balance neutral formula for the ionic compound you simply take the exponent (charge) from one ion and write it as the subscript (# of ions) of the other ion. Also if you have two of each it's the same as one of each if you simplify (you should always simplify if you can. Don't forget to use parentheses when needed. I have filled in some examples.
