Answer:
the number of moles is 0.279
Explanation:
The calculation of the number of moles of calcium nitrate, is given below;
As We know that
Number of moles = mass of substance ÷ molecular weight
where
Mass of substance is 45.8g
And, the molecular weight is 164.088
so,
= 45.8 g ÷ 164.088
= 0.279moles
Thus , the number of moles is 0.279
We simply used the above formula so that the accurate value could arrive
Oxygen, Nitrogen and Fluorine
Explanation:
In order to participate in a hydrogen bond, a hydrogen atom must be covalently bonded to one of the oxygen, nitrogen and fluorine.
- Hydrogen bonding is a type of dipole - dipole attraction between two specie.
- It is an intermolecular force of attraction.
- This bond type forms when hydrogen is bonded to a more electronegative atom.
- These atoms are oxygen, nitrogen and fluorine
- These species draws the electron shared more to themselves and leaves a partial positive charge on the hydrogen and a negative charge on them.
- The electrostatic force of attraction between the hydrogen of one molecule and the O/N/F of another molecule cause the formation of hydrogen bonds.
