Answer:
Magnesium oxide is a type of magnesium mineral supplement that is mostly made of magnesium—it actually contains more magnesium than other magnesium supplements. Magnesium oxide is acquired by burning magnesium with pure oxygen, but this method is quite costly.

London Dispersion Force between solute and solvent in each solution is the strongest type of intermolecular force.
<h3>What is London Depression Force ?</h3>
There are 4 types of intermolecular forces -
- Dispersion Force
- Dipole–Dipole
- Hydrogen Bonding, and
- Ion-Dipole.
The London dispersion force is a transient attractive attraction that occurs when two nearby atoms' electrons occupy locations that cause the atoms to form temporary dipoles. This force is also known as induced dipole-induced dipole attraction.
Example ; If these atoms or molecules come into contact with each other, dispersion forces exist between them. Consider the London dispersion forces between two chlorine molecules. Both chlorine atoms are connected in this case via a covalent connection formed by the equal sharing of valence electrons between two chlorine atoms.
Thus from the above solution we can say that in between these solutions London Depression force is the strongest force.

Answer:
The bee's energy output can be calculated directly, and related to its size. it only needs enough air resistance to counter its weight and enough power in its wings to sustain this resistance. it bee like that.
Molality is the number of moles of solutes in 1 kg of solvent.
the molality of solution to be prepared is 2.0 molal.
therefore 2 moles in 1 kg water.
the mass of Li₂S required is - 46 g/mol x 2.0 mol = 92 g
the mass in 1 kg of solvent is - 92 g
Therefore mass of Li₂S required in 1600.0 g is - 92 g/kg x 1.6 kg = 147.2 g
I think it is B
