The accompanying depictions show the electron distribution in the H₂O molecule is H : ₊°O°₊ : H.
The chemical formula of water is H₂O,
Electron configuration or electron distribution is the distribution of electrons of an atom or molecule (or other structure) in atomic or molecular orbitals, for example, the electron configuration of a neon atom is 1s²2s²2p⁶. Similarly,
The electronic configuration of O is 1s²2s²2p⁴,
So, it has a total of 6 valance electrons among them 2 are used to make bonds with H and the rest are present as lone pairs.
So, H₂O have two bonded pair of electrons and two lone pair of electrons. And the structure formed is,
H : ₊°O°₊ : H.

Answer is: conductivity in solution and solubility in water.
Ionic compounds conduct electricity, because it dissociate in ions and ions conduct electicity.
Ionic substances dissociate in water on cations and anions. For example, dissociation of potassium chloride in water: KCl(aq) → K⁺(aq) + Cl⁻(aq).
Ionic compounds (most of the salts, strong acids and bases) dissolve in water because an ion-dipole interactions.
An ion-dipole is electrostatic interaction between a charged ion (cations and anions) and a molecule that has a dipole (in this example water).
Dipole is a separation of positive and negative charges. In water, hydrogen has positive and oxygen has negative charge.
Yes that is true and this app is asking for 20 characters so I'm writing extra
Answer:
Explanation:
Given :
Mass of a bar of lead = 115.2 g
Initial water level = 25 mL
Final water level = 35.5 mL
Difference in the water level = 35.5 - 25
= 10.5 mL
=
We know that when a body is submerged in water, it displaces its own volume of water.
Therefore, the volume of the lead bar = volume of the water displaced = 10.5 mL =
We know that mathematically, density is the ratio of mass of body to its volume.
Density of the lead bar is given by :
=
