The NO3 polyatomic anion has a charge of 1-. Writing (NO3)3 means there are 3 such anions, each with a 1- charge, or a total charge of 3-. An example of this might be in the compound aluminum nitrate, Al(NO3)3.
-2
The charge of the lead ion in the compound lead phosphate, Pb3(PO4)2, is 2+.
The compound is neutral; the ions are Al(3+) and (NO3)-.
Ca(no3)2,ba(no3)2,pb(no3)2
Assuming cobalt(II) nitrate: Co(NO3)2 + Na2CO3 --> CoCO3 + 2NaNO3
-2
Mg(NO3)2 1 magnesium atom, 2 nitrogen atoms, and 6 oxygen atoms Mg(NO3)2 because the charge on Mg is +2 and the charge of NO3 is -1 so you would need to balance. Magnesium has 2+ and Nitrate is one of the common polyatomic ions: NO3^1- Combine them both: Mg1(NO3)2 ===> Mg(NO3)2
-1 or -2 i cant remember but im pretty sure -1.
The charge of the lead ion in the compound lead phosphate, Pb3(PO4)2, is 2+.
The formula and charge of the nitrate ion is NO3-, and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium nitrate, Mg(NO3)2.
Mg(NO3)2 is called magnesium nitrate. You do not use the prefix di for the nitrate since this is an ionic compound, and it can only be (NO3)2 as nitrate has a -1 charge and Mg has a +2 charge.
Fe(NO3)3 Since Iron has two charges the terms ferric and ferrous are used to distinguish between the two charges when in a compound. Ferric refers to the higher charge of iron which is 3+ and ferrous refers to the lower charge of iron which is 2+. So ferrous nitrate has an iron charge of 2+ and since NO3 has a 1- charge to balance the compound it becomes Fe(NO3)2
Ca(NO3)2
no, it has a negative charge
Most people will answer this:ZnCl2 + 2AgNO3 --> Zn(NO3)2 + 2AgClBut actually in solution (where this reaction could only take place!) only two of 4 ions react:Cl- + Ag+ --> (AgCl)sThe other ions: NO3- and Zn2+ stay unchanged in solution (tribune ions)
There are two possible reactions for HNO3 + BaCO3. They will either form BA(NO3)2 and carbon dioxide and water, or hydrogen carbonate. The equations are HNO3 + BaCO3 = Ba(NO3)2 + CO2 + H2O or HNO3 + BaCO3 = Ba(NO3)2 + H2CO3.
Nitrate has a single, negative charge - NO3-
