So its the beginning of chemistry and I don't know how to make formulas. BUT its very important I learn now otherwise I will have a very hard year...
For ex:
It says, "Fill in the correct formulas for the given anion and cation."
SO2-4 and Al3+ (how do i combine those two to make a formula)
Another ex:
Al3+ and Cr2O2-7
PLEASE EXPLAIN HOW TO DO THESE.
Thanks so much for any help:)!
