Can someone check my compounds naming please? appreciated?

Question

Hg(MnO4)2 = mercury permanganate
CO=carbon monoxide
CaHPO4=calcium hydrogen phosphate
AL(OH)3=aluminum hydroxide
K2SO4=potassuim sulfate
N2 O5=dinitrogen pentaoxide
Ni O=nitrogen monooxdie

Answer 1

Hg(MnO4)2 = mercury (II) permanganate or mercuric permanganate

N2O5 = dinitrogen pentoxide (just spelling)

NiO = nickel (II) oxide or nickelic oxide (not nitrogen)

The others are OK.

Answer 2

Ok, well, there is many different polyatomic ions and binary compounds that are in nature. Try trillions. However, there is a chart on the NYS chemistry reference table that gives you the names and charges of some polyatomic ions. However, there are so many that there isn't a way to know every single polyatomic ion out there. However, binary compounds are relatively easy. Especially if they are ionic compounds. Ok, take this formula, KCl, potassium chloride, you change the chlorine to chloride, the -ide tells the scientist(s) that the compound only consists of potassium and chlorine. Same for CaO, calcium oxide, whereas, you need to check the charge that the ion makes. Oxygen-ion makes a 2- charge, and Calcium makes a 2+ charge... So take sodium, which has a 1+ ion charge, and Oxygen, you need to balance the # of atoms, so Na(subscript of 2)O is the correct formula, just an FYI.

Answer 3

No there are a few mistakes in them..sry i forgot the naming abut a few mistakes that i can point are :

1st-it should be mercurous
6th-Its nickel not nitrogen


Wait ill just take out my old book for u and try to give as right answers as possible :)
ill just edit this answer soon hold on


umm u already got some right answers so cheers

Answer 4

Last compound is wrong, not nitrogen monoxide, but nickel oxide.

also N2O5 dinitrogen pentaoxide sounds a little weird, most commonly called nitric pentoxide.

the others look ok,

Answer 5

K2SO4 is potassium sulfate though i guess it was just a spelling mistake
N2O5 is dinitrogen pentoxide
NiO is Nickel oxide (or if it was NO then nitrogen monoxide)
The others are good i guess.

Answer 6

Just so you know, Ni (in your last question) is nickel, not nitrogren. So it would be Nickel (II) Oxide. But the rest of them are right.

Answer 7

1) mercury(II)

3) dihydrogen phosphate

6) pentoxide

7) nickel oxide

the others are fine.

Answer 8

looks right
