How many nitrogen atoms are there in 7.5 g of CaNO32?
The species is; Ca(NO3)2 ( NO3(-) is a polyatomic ion and is in parenthesis ) 7.5 grams Ca(NO3)2 (1 mole Ca(NO3)2/164.1 grams)(2 mole N/1 mole Ca(NO3)2)(6.022 X 10^23/1 mole N) = 5.5 X 10^22 atoms of nitrogen
How many ions present in calcium nitrate?
The calcium ion is Ca2+ and the nitrate ion is NO3- and together they form Ca(NO3)2
How many nitrogen atoms are in CaNO33?
Ca(NO3)2Number of atoms in the compound:Ca- 1N- 2O- 6Find the atomic masses of all atoms and add:Ca = 40.1N = 2 * 14.0 = 28.0O = 6 * 16.0 = 96.0___________________164.1 gEquation:# moles * added atomic mass = # gramsAnswer:4.2 moles * (164.1 g) = 689.22 grams of Ca(NO3)2
What elements make up calcium nitrate?
Calcium nitrate - Ca(NO3)2- contain Ca, N and O.
What is the percent composition of calcium acetate?
From its chemical formula, Ca(NO3)2, you can tell that there are two nitrate ions for every calcium atom. Therefore the mole ratio of calcium to nitrate is 1:2. So one could say that the "nitrate content" of calcium nitrate is 2/3 or 66.7%.
What is calcium nitrate composed of?
Ca+2 + NO3-1 = Ca(NO3)2
What do you get when you mix Ca plus 2 and NO3 -1?
You will make Calcium Dinitrate or Ca(NO3)2
What is the formula for the salt which contains both Ca and NO3 ions?
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.
How many nitrogen atoms are there in 7.5 g of CaNO32?
The species is; Ca(NO3)2 ( NO3(-) is a polyatomic ion and is in parenthesis ) 7.5 grams Ca(NO3)2 (1 mole Ca(NO3)2/164.1 grams)(2 mole N/1 mole Ca(NO3)2)(6.022 X 10^23/1 mole N) = 5.5 X 10^22 atoms of nitrogen
How many ions present in calcium nitrate?
The calcium ion is Ca2+ and the nitrate ion is NO3- and together they form Ca(NO3)2
What is the compound formed from Ca2 and NO3 -1?
The compound formed is calcium nitrate, Ca(NO3)2. Calcium forms a +2 ion and the nitrate polyatomic forms a -1 ion. In order to balance out the charges, you need two nitrate ions to bond with one calcium. This ratio is reflected in the formula, which places the nitrate in parentheses with the "2" subscript outside it, which means there are two of them.

What is the number of atoms in Ca(NO3)2?
This compound is calcium nitrate. Each formula unit will contain 9 atoms.
What elements make up calcium nitrate?
Calcium nitrate - Ca(NO3)2- contain Ca, N and O.
Does NO3 have a positive or negative charge?
According to the endless studying I have done in college involving chemistry, NO3 which is called nitrate has a negative charge of 1 or written as -1. If you need help remembering the charge, just think of nitric acid ( HNO3) where the Hydrogen has a positive 1 charge, which means the NO3 has to have a -1 charge.
What is the oxidation number of Ca(NO3)2?
The sum of the oxidation numbers is zero for the compound.
