valency of dichromate in potassium dichromate
Valence is a property of atoms (or of particles acting in similar roles), not of molecules, and ammonium sulphate consists of molecules. So it doesn't have a valency. Please see the link.
17.72%, please see the molecular weight calculator in related links
Ferric Chloride = FeCl3Ammonium Hydroxide = NH4OHFerric (III) Chloride + Ammonium Hydroxide = Ferric (III) Hydroxide + Ammonium Chloride FeCl3 + 3NH4OH = Fe(OH)3 + 3NH4Cl
You probably mean lead chromate since you have mentioned an oxidation state of 2+ for the lead ion and the chromate ion has an oxidation state of 2-. Lead chromate is yellow. Please see the link.
Use the letter 'M' . The number of oxygen atoms in the metal oxide depends on the Group in the periodic table. Group (I) = M2O Group(II) = MO Group (III) = M2O3 Group (IV) = MO2 The transition metal have variable oxidations. They can be M2O, M2O3 , MO, M3O4

When you resubmit your question would you please indicate to whom or what the ammonium chloride is to be administered.
please i wish to know about the sources of ammonium hydroxide, its mechanism and effect on aquatic system, please post it to kolledm@yahoo.com. thanks
No, they are distinct compounds. Please see the links.
It's prepared by dissolving ferrous and ammonium sulphate in water with some sulphuric acid and recrystallising. For details please see the wikipedia article about ammonium iron (II) sulfate.
Forms the ions NH4+ and NO3-. Please see the link.

I'm having trouble finding an answer to this question. Please check back later.
Apparently no longer used. Formerly used as an anti-convulsive and sedative. Please see the link.
Please make your question more specific.
please can anyone help me in finding this answer??
Please clarify your question - a false positive finding for what condition?
