Hi there,
Attached is my homework, with question and answer.  Can someone please look it over quickly and tell me if i am doing it correctly?  I am not sure about many questions and think i should read more before finishing the rest.  I would check my text book but it doesnt provide the answers and i have no way of knowing unless i wait for the teacher until tommorrow.

Hydrochloric Acid = HCl (aq)

I think  most are correct and you have approached this in a systematic way

In naming, I think you need to add the oxidation state for all metals that can take two or more oxidation states in conjunction with a particular polyatomic ion.

So

15 g) Lead (II) Carbonate

16a) is calcium and you have written Na

16 c) Hypochlorate is ClO^-  not CIO^-

16h) Sodium hydroxide - no need for brackets as OH is interpreted as one symbol

16 i) simililarly to previous, no brackets needed

17 c) Mercury (I) carbonate ? because mercury can take multiple oxidation states - not sure if applies to carbonate though !

17 j) Antimony (V) Chlorate

17 l) Potassium Bromite ?

16 g) Al (ClO)₃ not Al(CIO)₃ - strictly your formula has carbon and iodine rather than chlorine as you intended.

16 j) NiPO₄ ? http://en.wikipedia.org/wiki/Phosphate


Seems a lot, but only minor points really.

Thank you very much sir,
Today we did more of this, i realized i was getting ahead of myself.
Thanks again for your time! Next is covalent bonds and naming.

Awesome forum here.  I have taken physics and went to college for 3 years for an automation and robotics course.  Now im gearing up toward electrical engineering, but have never taken chemistry before, in the future ill help out if i can.
