Answer:
3 moles of 
is needed for 
to be fully consumed.
Explanation:
For the balanced equation:
⇒ 
First, find the moles of Na corresponding to the 69g used the general definition of mol:
We observe that the equation is balanced and the stoichiometric ratio between them is 1: 1.
According to this, one mole of Na will react with one mole of Cl.
3 moles of is needed for to be fully consumed.
the mole concept :
a mole (mol) is defined as the amount of substance that contains as many atoms, molecules, icons, electrons or any other elementary entities as there are carbon atoms in exactly 12 gm of. the number of atoms in 12gm of is called Avogadro's number.

Answer:
Functional groups
Explanation:
A functional group refers to an atom or cluster of atoms that are covalently bonded to carbon and influence the behavior of organic compounds.
There are several functional groups in organic chemistry that determine the properties of organic compounds.
For instance, in the compound CH3CH2CH2CH2OH, the functional group is the -OH group. The chemical and physical properties of this compound is largely determined by this functional group.
