Name the following compounds: caf2 na2o bas cuso4 fe2o3 hgcl2 (chlorine not carbon and iodine) kc2h3o2 al(oh)3 (aluminum) fe(no3)3 n2o5 po5 (all numbers should be subscripts)

CaF2 = Calcium fluoride (leave it as is, it in emoerical form already)

Na20 = Sodium oxide (leave it as is, it in emoerical form already)

BaS = Barium Sulfide (leave it as is, it in emoerical form already)

CuSO4 = Copper(II) sulfate = CuSO4 5H2O

Fe2O3 = Iron(III) oxide (leave it as is, it in emoerical form already)

HgCl2 = Mercury(II) chloride (leave it as is, it in emoerical form already)

KC2H3O2 = Potassium Acetate (leave it as is, it in emoerical form already)

Al(OH)3 = Aluminium hydroxide (leave it as is, it in emoerical form already)

Fe(NO3)3 = Iron(III) nitrate (leave it as is, it in emoerical form already)

N2O5 = Dinitrogen pentoxide = N2O5 (it's subscrip is already simplified)

PO5 = Phosphorus pentoxide = P2 O5 (there was just no 2 after the P so that's all that was needed there)

I'm am so sorry if this didn't help too much, I hope I did help, I in some way, have a wonderful day.

c (diamond),

sio2 (quartz)
