NO3- stands for nitrate anion. It has to have one negative charge ( .- ) in superscript position.
Mg(NO3)2 {note correct case for "O"} is not an element at all. Instead it is a compound of three elements, magnesium, nitrogen, and oxygen.
In the formula Mg(NO3)2, there is 1 magnesium atom, 2 nitrogen atoms, and 6 oxygen atoms.
The balanced chemical equation for the reaction between lead (II) nitrate (Pb(NO3)2) and potassium iodide (KI) is: Pb(NO3)2 + 2KI -> PbI2 + 2KNO3 This equation is already balanced as it has the same number of atoms of each element on both sides of the reaction arrow.
To calculate the percent by mass of oxygen in Cr(NO3)3, we need to consider the molar mass of each element. Cr(NO3)3 consists of one chromium atom, three nitrogen atoms, and nine oxygen atoms. The molar mass of Cr(NO3)3 is 274.06 g/mol. The molar mass of just the oxygen atoms in Cr(NO3)3 is 144.00 g/mol. Therefore, the percent by mass of oxygen in Cr(NO3)3 can be calculated as (144.00 g/mol / 274.06 g/mol) x 100%.
The products in the reaction of Zn(NO3)2 with 2 NaOH are Zn(OH)2(s) and 2 NaNO3 . There are no 'elements' involved
Mg(NO3)2 {note correct case for "O"} is not an element at all. Instead it is a compound of three elements, magnesium, nitrogen, and oxygen.
No. It is an ion with two different elements: nitrogen and oxygen.
In each molecule of NO3, there is one nitrogen atom and there are three oxygen atoms.
Calcium nitrate is a compound: Ca(NO3)2.

Copper: 2+Oxygen: 2-Nitrogen: 5+
You can treat a polyatomic ion as an element when balancing equations. The following example involves the polyatomic ion NO3-. Notice that the entire polyatomic ion is placed in parentheses and given its own subscript. 2Al(s) + 3Mg(NO3)2(aq) --> 2Al(NO3)3(aq) + 3Mg(s)
There is no Mo3. Possibly you are thinking of NO3 which is nitric oxide.
Compound????
Explain why element symbols appear on both sides of a chemical equation? The arrow sign means what ever is on the left side must be on the right side, but it does not have to be in the same form. Ex. 2 KI + Pb( NO3)2 = 2 KNO3 + PbI2 On the left side K is bonded to I, and Pb is bonded to NO3. On the right side K is bonded to NO3, and Pb is bonded to I..
