How many oxygen atoms are in 2(NO3)

torisob [31]

6 Oxygen atoms

Explanation:

In the molecule 2(NO₃):

An atom is the smallest indivisible particle of any substance. They chemically combine to give compounds and molecules. Some of them are able to exist on their own.

An element is a substance that has a unique atom.

NO₃ has two elements: N and O

Number of atoms:

N = 1

O = 3

but we have two moles of NO₃

O = 3 x 2 = 6

N = 1 x 2 = 2

What are the two different ions present in the compound al(no3)3?

Aleks [24]

$Al^{3+}$ and $NO_3^{-}$

Aluminum nitrate is an ionic compound, meaning that it is made up cations and anions. By convention when writing the formula for an ionic compounds the cation part shall be placed in front the anions. Thus the cation would contain aluminum and the anion shall be a polyatomic nitrate ion consisting of nitrogen and oxygen. The bracket with subscript 3 attached resembles the ratio between the two species, aluminum ions and nitrate ions. For each aluminum ion in the compound there shall be three corresponding nitrate ions.

Aluminum form ions of charge +3 whereas nitrate ions are of charge -1. Write the charge of the ion as the superscript in reverse (i.e., write $3+$ as in $Al^{3+}$ and $-$ in $NO_3^{-}$ , omitting any 1.)
