Answer:
Water has polar O-H bonds. The negative O atoms attract the positive H atoms in nearby molecules, leading to the unusually strong type of dipole-dipole force called a hydrogen bond.
Explanation:
- NH₃: Hydrogen bonds;
- CCl₄: London Dispersion Forces; (a.k.a. Induced dipole)
- HCl: Dipole-dipole Interactions.
<h3>Explanation</h3>
Relative strength of intermolecular forces in small molecules:
Hydrogen bonds > Dipole-dipole interactions > London DIspersion Forces.
It takes two conditions for molecules in a substance to form <em>hydrogen bonds</em>.
- They shall contain at least one of the three bonds: H-F, O-H, or N-H.
- They shall contain at least one lone pair of electrons.
NH₃ contains N-H bonds. The central nitrogen atom in an NH₃ molecule has one lone pair of electrons. NH₃ meets both conditions; it is capable of forming hydrogen bonds.
CCl₄ molecules are nonpolar. The molecule has a tetrahedral geometry. Dipole from the polar C-Cl bonds cancel out due to symmetry. The molecule is nonpolar overall. As a result, only London Dispersion Force is possible between CCl₄ molecules.
HCl molecules are polar. The H-Cl bond is fairly polar. The HCl molecule is asymmetric, such that the dipole won't cancel out. The molecule is overall polar. Both dipole-dipole interactions and London Dispersion Force are possible between HCl molecules. However, dipole-dipole interactions are most predominant among the two.
evaporation systems allow for an endless source of water. you can grab cups of water straight from the sea or even a lake. the use of evaporation allows for you to drink water thats even healthier than getting it from a cloud and it will leave all of the bad parts that used to be in the water in the first container you pour into. this system is most useful in hot climates such as places near the equator.
The volume occupied by the argon gas is, 1.44 L
Explanation :
To calculate the volume of argon gas we are using ideal gas equation:
where,
P = pressure of argon gas = 1528 torr = 2.010 atm
Conversion used : (1 atm = 760 torr)
V = volume of argon gas = ?
T = temperature of argon gas = 
R = gas constant = 0.0821 L.atm/mole.K
w = mass of argon gas = 4.24 g
M = molar mass of argon gas = 39.95 g/mole
Now put all the given values in the ideal gas equation, we get:
Therefore, the volume of occupied by argon gas is 1.44 L
276mph that is easy because you times 11.5 with 24 which is the total number of hours per day
