<h3>Answer:</h3>
1.0 × 10⁻⁶ M (Option-A)
<h3>Solution:</h3>
Data Given:
pH = 6
[H⁺] = ?
Formula Used:
As we know pH is given as,
pH = -log [H⁺]
and,
[H⁺] = 10^-pH ----- (1)
Putting value of pH in eq. 1,
[H⁺] = 10⁻⁶ ∴ 10 = Antilog
[H⁺] = 1.0 × 10⁻⁶ M
D represents ion-dipole forces that are stronger than the force C.
Explanation:
D represents the ion-dipole force.
C represents the H-bonding forces.
ion-dipole force is a force that is due to electrostatic attraction and has a dipole between an ion and a neutral molecule.
It is electrostatic in nature.
A hydrogen bond is the force between the hydrogen with the electro negative atom of one molecule, to electro negative atom of some other molecule. such as: O, F, N
Ion dipole force is stronger than the H-bonding.
Answer:
One change of state happens when you add energy to the substance. This change of state is called melting. By adding energy to the molecules in a solid the molecules begin to move quicker and can break away from the other molecules.
Answer:
It will be : (in simple terms)
Condensation of hot steam or hot vapor on the cooler skin releases the water's latent heat of vaporization, rapidly raising the temperature of the skin which will result in steam burns.

All the best!!
A blizzard will cause white out conditions so you can't see, it will also cause black ice so a person or vehicle will slip. The heavy snow will hang on wires and branches causing them to break.
