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.
