How do I write the chemical formula for an ionic compound?

Write each element symbol and their oxidization number, if the numbers cancel out, you drop them, if they don't swap them.

300

How do I write the chemical formula for a covalent compound from the name?

Look at the prefixes, write the symbols and subscript based on the prefix.

The half-life of Zn-71 is 2.4 minutes. If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed?

7.2 / 2.4 = 3 half-lives

100/2 = 50

50/2 = 25

25/2 = 12.5

12.5 grams
