Here, as they both are physical things without any magnetic property & density difference, screening would be best.
In short, Your Answer would be Option C
Hope this helps!
Answer : The boiling point of water increases, 
Solution : Given,
Moles of solute (sugar) = 4 moles
Mass of solvent (water) = 1 Kg

i = 1 for sugar
Formula used :

Where,
= elevation in boiling point
= elevation constant
m = molality
= moles of solute (sugar)
= mass of solvent (water)
i = van't Hoff factor
Now put all the given values in this formula, we get the elevation in boiling point of water.

Therefore, the elevation in boiling point of water is 
Answer:
In sea water;
The salt is the solute while the water is the solvent
In soda water;
The water is the solvent, the carbon dioxide is the solute
In air;
The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes
Explanation:
A solution is a homogeneous mixture of two or more substances which includes a solvent and a solute. A solute in a solution is dissolved in the solvent of the solution.
Therefore, the solvent is the major part of a solution as it takes in the solvent to form the solution.
In sea water, a solution with a high concentration of salts
The salt is the solute while the water is the solvent
In soda water, which is a mixture of CO₂ in water,
Here we have in the soda solution, the water is the solvent while the carbon dioxide is the solute
The water is the solvent, the carbon dioxide is the solute
Air a solution made up by a mixture of Nitrogen 78%, oxygen 21%, and small amount of water carbon dioxide and argon
The nitrogen is the solvent while the oxygen and the other substances in small amounts are the solutes.
Answer:
If temperature increases, the number of collisions per second also increase because particles absorb energy.

Answer:
12 Neutrons
1 Valence Electron
23 ions [11 Protons and 12 Neutrons]
22 ions [11 Electrons and Protons]
Explanation:
To find the number of neutrons in an element, you simply take its atomic number and deduct that from the atomic mass [<em>round</em><em> </em>if necessary]. There is one <em>valence </em><em>electron</em><em> </em>because<em> </em>according to the Periodic Table of Elements, the first three energy levels can fit 2 - 8 electrons:
1st Energy Level → 2 Electrons
2nd Energy Level → 8 Electrons
3rd Energy Level → 8 Electrons
4th Energy Level → 18 Electrons
5th Energy Level → 18 Electrons
6th Energy Level [Lanthanide Series] → 32 Electrons
7th Energy Level [Actinide Series] → 32 Electrons
So, as you can see, 2 + 8 gives you 10. So from there, we already filled up 2 energy levels. Now going to the third one will leave us with only one electron left over. That is where that valence electron is.
