Question

ok it says give the formula for this one Hydronitric acid, I put H3N
For Iron (III) chloride I put Fe3Cl
Silver acetrate i put AG1C2
Ca(OH02 i put calcium oxide
for CCL4 I had no clue
Mercury (II) oxide i put HG2O
NaClO3 I put Sodium chlorate
for (NH4)2SO4 i put hydronitrate Sodium
Fe2S3 I put Iron sulfrate

Answer 1

right on the hydronitric acid.
right on sodium chlorate

wrong on the others.
What does Iron(III) mean? does it mean Fe⁺³?
what is a tetrachloride?
what is ammonium?
on the last, you have to put in the II or III on the iron, and it is a sulfide, not sulfate. You need to memorize the polyatomic ions.

Answer 2

FeCl3
AgC2H3O2
carbon tetrachloride this is CCl4 right?
HgO
ammonium sulfate
iron(III)sulfide
alright now all I need help with is Ca (OH)2

Answer 3

all ok, calcium hydroxide. Memorize those polyatomic ions.
