Answer:
Explanation: Avogadro number,N, = 6.02214076*10^23per mole —> 22.71L
—>( 7.41*10^26/N)*22.71 = 22.79*10^3 = 22,790L

Answer:
The correct option is: 2 shared pairs, 2 lone pairs
Explanation:
Water is an inorganic molecule that is composed of one central oxygen atom and two hydrogen atoms bonded by covalent bonds. The molecular formula of water is H₂O and the bond angle is 109.47°.
The <em>oxygen is sp³ hybridized</em> and there are<em> two bond (or shared) pairs and two lone pairs </em>of electrons in a water molecule. The<em> structure of H₂O is bent </em>due to the <u>repulsive forces between the lone pairs of electrons</u>.
<em>Due to these repulsive forces, the H-O-H bond angle decreases from 109.47°, which is the ideal bond angle to 104.45°.</em>
