Naming and writing formulas of compounds

AI Thread Summary
The discussion revolves around naming chemical compounds and writing their formulas. Participants attempt to name various compounds like ZnI2 and BrF, with corrections highlighting common mistakes, such as confusing Br for barium instead of bromine. The correct naming of compounds like zinc iodide, calcium hydride, and copper nitrate is emphasized, while errors in formulas for zinc sulfate and gold(III) nitrate are pointed out. The conversation also addresses the importance of understanding chemical symbols and the systematic approach to naming and formula writing. Overall, the thread serves as a learning platform for students struggling with inorganic chemistry nomenclature.

Name the following :ZnI2, BrF, FeSO3, CaH2, BaHPO3,CuNO3, AgIO, SO2

write the correct formula of these: zinc sulphate, barium nitrate, gold(III)nitrate, barium chloride, mercurous nitrate, antimony(V)cloride, ferrous bromide, calcium carbonate and hydrobromic acid.


i have attempted them as aswell...
ok...so i got these...
ZnI2 - Zinc Iodide
BrF-Barium Floride
FeSO3- Iron sulphite
CaH2- Calcium hyroxide
BaHPO3-Barium hypophosphate
CuNO3- Copper Nitrate
AgIO2- Gold(II)Idoxide
SO2- Sulphide

For the formulas i got...
zinc sulphate- ZnSO3
barium nitrate-BaNO3
gold(III)sulpahte- AgSO3
barium chloride- BaCl
mercurous nitrate- i don't get this one!
antimony (V) cloride- AtCl5
ferrous bromide- FeBr
calcium carbonate- CaCO3
hydrobromic acid- HBO3

ZnI2 - Zinc Iodide
BrF-Barium Floride
What is Br the symbol for? (It's not barium)
FeSO3- Iron sulphite
CaH2- Calcium hyroxide
No, calcium hydroxide is Ca(OH)2. The formula you are trying to name does not have the oxygen in, and so is calcium hydride.
BaHPO3-Barium hypophosphate
I'm not sure about this one.
CuNO3- Copper Nitrate
correct
AgIO2- Gold(II)Idoxide
Well, Ag is silver. To be honest, I don't know this one either!
SO2- Sulphide
That's not correct. What is CO2? Can you tell from this what SO2 is?

For the formulas i got...
zinc sulphate- ZnSO3
No. You seen to be getting confused with the oxyanions. Compounds ending in SO4 are sulphates; compounds ending in SO3 are sulphites.
barium nitrate-BaNO3
correct
gold(III)sulpahte- AgSO3
The chemical symbol for Gold is Au. Also, I'm sure the question says gold(III) nitrate. What does the III in brackets mean?
barium chloride- BaCl
No, your charges on this compound don't balance. Look at which groups each element is in in the periodic table.
mercurous nitrate- i don't get this one!
I think mercurous means the 1+ ion of mercury.
antimony (V) cloride- AtCl5
At is astatine-- check your periodic table!
ferrous bromide- FeBr
Ferrous means iron(II) ions
calcium carbonate- CaCO3
correct
hydrobromic acid- HBO3
B is no the symbol for bromine. Do you know the formula for hydrochloric acid? If so, can you get from this the formula for hydrobromic acid?[And, for the record, I'm not a chemist, and haven't taken chemistry for quite a while-- that's why I don't know the answres to some of the questions! Someone who does know them will be along soon, I'm sure!]

Barium nitrate is not BaNO3.

Chemzz, it looks like you're guessing many of these. There's a systematic way to do these that you need to learn first.

See the link in the above post, as well as http://www.ausetute.com.au/wriiform.html

Sorry, it's not-- my bad :blushing:
 
Br stands for bromine and B stands for boron
 
Barium biphosphite
 
hi. I'm a student that doesn't understand how to write the formulas to compounds. if you could help me, please do. thanks.
