The electronegativity of the element affects the ability of its compounds to dissolve in different solvents.
<h3>What is the meaning of electronegativity?</h3>
Electronegativity is a measure of an atom's ability to attract shared electrons to itself.
Polar bonds have a positive and negative side to them, and therefore can attract water dipoles and dissolve in water.
If the polarities of the solvent and solute match (both are polar or both are nonpolar), then the solute will probably dissolve.
If the polarities of the solvent and solute are different (one is polar, one is nonpolar), the solute probably won't dissolve.
Hence, option D is correct.

Answer:
2.11 x 10²⁴ molecules.
Explanation:
- <em>It is known that every 1.0 mole of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).</em>
<em><u>Using cross multiplication:</u></em>
1.0 mole of H₂O contains → 6.022 x 10²³ molecules.
3.5 mole of H₂O contains → ??? molecules.
∴ 3.5 mole of H₂O contain = (3.5 mol)(6.022 x 10²³) = 2.11 x 10²⁴ molecules.

Answer:
I think that it might be cytoplasm
Explanation:
I got this from google
Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins.
