Van der waals forces < hydrogen bonding forces < Crystal lattice forces.
Explanation:
Hydrogen bonds are very strong intermolecular forces. They are a special dipole-dipole bonds formed by the attraction between hydrogen atom of one molecule and an electronegative atom of another molecule.
- Hydrogen bonds are stronger than van der waals forces.
- Van der waals forces are weak attractions joining non-polar and polar molecules together.
- Hydrogen bonds are more effective in binding molecules together.
- Crystal forces are found in solids and are strong electrostatic forces of attraction between oppositely charged ions

Lower water levels can contribute to higher concentrations of natural and human pollutants. Less water going down the drain means more water available in the lakes, rivers and streams that we use for recreation and wildlife uses to survive.
Answer:
C) 14.1 moles
Explanation:
1 mole = 6.02 *10^ 23
8.50 * 10^24 molecules *(1 mole/6.02*10^23 molecules) ≈ 14.1 moles
Hey :)
I’m sure it’s 7
Because the mass number of any element is the number of protons and neutrons
Hope this helps :)
Caffeine is a Central Nervous System stimulant of the methlyxanthine class. It is the world's most widely consumed psychoactive drug. Unlike many other psychoactive substances, it is legal and unregulated im nearly all parts of the world.
