Storms are disturbances in atmospheric conditions. The four severe storms are thunderstorms, lightning, heavy rain, and blizzards.
<h3>What are blizzards?</h3>
Blizzards are the type of storm that includes high wind at 40 km/h and also have snow and cold air that makes the temperature drop and causes poor visibility.
Thunderstorms and lightning occur with high electrical charge release during high wind and rain. Heavy rains are severe types of storms as they can cause a flood.

Answer:
Kr- Dispersion Forces
H2O- Hydrogen Bonding
CHCI3- Dipole-Dipole Forces
HF- Hydrogen Bonding
C2H6- Dispersion Forces
HBr- Hydrogen Bonding Forces
Explanation:
Dispersion forces occurs in all substances. They are the dominant intermolecular interaction in all non polar substances such as C2H6 and Kr.
Hydrogen bonding occurs when hydrogen is bonded to a highly electronegative atom such as Cl, Br, O etc. It is the dominant intermolecular interaction in HF, HBr and H2O.
Dipole-Dipole interactions occur when a permanent dipole exists in a molecule such as in CHCI3
Answer:
Explanation:
Remark
CH2 provides the basic structure of the hydrocarbon. It will be multiplied by some factor determined by the number of grams / mol. I will use rounded numbers because all periodic tables are slightly different.
Theoretical mass of CH2
1 C = 1 * 12 = 12
2 H= 2 * 1 = 2
Mass CH2 = 14
The multiplier for CH2
56.108 rounded = 56
Multiplier = molar mass (rounded)/Mass CH2
Multiplier = 56/14 = 4
Chemical
(CH2)_4 = C4H8
Answer: C4H8
