Well, I'm currently failing the class of chemistry which I take as a honors course due to the exams being 55% of my grades. I've began to taken it seriously now and I really need help with some stuff in there.
Chemical Names and Formulas-
my teacher expects me to know most of the anions like acetate and thiosulfate and their formulas.. which i dont get much because as notes he gave us this: Potassium Permanganate is K+1 MnO1/4(the numbers are suppose to be small) and equals to KMnO4(on top) which makes no sense whatsoever to me.. and a second example he gave was Iron(III) dichromate is Fe+3Cr2O7(bottom)2-(top) equals Fe2(Cr207)2.
can anyone please explain it better than this teacher i have for chemistry? because he really doesnt explain it well or i just dont get it.. and for the people who dont get what the point of this is I NEED HELP WITH THE CHEMICAL NAMES AND FORMULAS OF CATIONS AND ANIONS WHEN THEY ARE TOGETHER/SEPARATE!
