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.
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.
Ferric Chloride = FeCl3Ammonium Hydroxide = NH4OHFerric (III) Chloride + Ammonium Hydroxide = Ferric (III) Hydroxide + Ammonium Chloride FeCl3 + 3NH4OH = Fe(OH)3 + 3NH4Cl
The formula for ammonium bicarbonate is NH4HCO3. To find the mass percent of nitrogen (N), calculate the molar mass of nitrogen in the formula and divide it by the molar mass of the entire compound NH4HCO3. The molar mass of N is 14.01 g/mol, and the molar mass of NH4HCO3 is 79.06 g/mol. Therefore, the mass percent of nitrogen in ammonium bicarbonate is (14.01 g/mol / 79.06 g/mol) * 100% = 17.7%.
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.
Forms the ions NH4+ and NO3-. Please see the link.
There is no such solution.You probably mean KMnO4 which is Potassium Permanganate solution.
To prepare ferrous ammonium sulfate, commonly known as Mohr's salt, dissolve iron(II) sulfate and ammonium sulfate in water separately. Combine the two solutions and allow the double displacement reaction to occur, resulting in the formation of ferrous ammonium sulfate. Finally, crystallize the solution to obtain the solid compound.
I'm having trouble finding an answer to this question. Please check back later.
Please make your question more specific.
please can anyone help me in finding this answer??
Apparently no longer used. Formerly used as an anti-convulsive and sedative. Please see the link.
Please clarify your question - a false positive finding for what condition?
