If the sun was not there the earth would travel in a straight line
Answer is: hydrogen bonding.
Methanol has stronger intermolecular bonds than methane.
Intermolecular forces are the forces between molecules or particles.
There are several types of intermolecular forces: hydrogen bonding, ion-induced dipole forces, ion-dipole forces andvan der Waals forces.
Hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (H), covalently bound to a highly electronegative atom such as flourine (F), oxygen (O) and nitrogen (N) atoms.
Answer: Option (b) is the correct answer.
Explanation:
Buffere is defined as the solution to whom when an acid or base is added then it resists any in change in pH of the solution.
This is because a buffer has the ability to not get affected by the addition of small amounts of an acid or a base. So, basically it keeps the concentration of both hydrogen ions and hydroxides equal. As a result, it helps in maintaining the pH of the solution.
And, the capacity of a buffer solution to resist the change is known as buffer capacity.
Thus, we can conclude that buffering capacity refers to the extent to which a buffer solution can counteract the effect of added acid or base.
Answer:
Gas:
- No fixed shape or volume
- Molecules are very loosely packed
- Flows in all the directions
Liquid:
- No fixed shape but has volume
- Molecules are closely packed
- Always flows from higher to lower level
Mass number = protons + neutrons. 12 + 11 = 23.
