Depends on how you look at it. There are a total of 4 atoms (1N and 3O) but there are only 2 different atoms (Nitrogen and Oxygen).
(NO3)- has three single bonds.
The formula for the salt containing both Ca and NO3 ions would be Ca(NO3)2. This is because calcium (Ca) has a 2+ charge and nitrate (NO3) has a 1- charge, so to balance the charges, you need two NO3 ions for each Ca ion.
The formula for the ionic compound formed by magnesium ions (Mg2+) and nitrate ions (NO3-) is Mg(NO3)2. The formula for the ionic compound formed by calcium ions (Ca2+) and nitrate ions (NO3-) is Ca(NO3)2.
Al(NO3)3(aq) ===> Al^3+(aq) + 3NO3^-(aq) is how aluminum nitrate ionizes in aqueous media.
The empirical formula for Co(NO3)2 is Co(NO3)2. The compound is named cobalt(II) nitrate.
NO3 is known as nitrate.
The molecular formula is Co(NO3)2Co(NO3)2
Iron nitrates are: - Fe(II)(NO3)2 - Fe(III)(NO3)3
The formula for the nitrate ion is NO3 -1.
Chromium (III) Nitrate
NI(NO3)3+pbbr4nibr3+pb(no3)4
NO3 is commonly known as nitrate.
Mg(NO3)2
the equation would look like: 2(NO3) + Fe --> Fe(NO3)2 the 2 in front of the NO3 is there to balance the equation.
Al(NO3)3 is aluminum nitrate.
Hg22+ + NO3- -----> Hg2(NO3)2
(NO3)- has three single bonds.
