TEST 3

Does anyone know if the equation for the FC will be provided on test 3?

The only equations given are the ones on the sheet given on every test. The Formal charge equation is just FC = Valence - [Lone Pairs + (1/2 Bonding Pairs)]. It would behoove you to memorize it.

I noticed that there was an extra equation given in test 2 compared to test 1 so I was wondering in case^^
Thank you though!

I would not think so, though it's a relatively simple formula so they might expect you to memorise it.

You don't need the formula; count how many electrons are associated with an element and subtract the number of electrons from the number of valence electrons of that element.
