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:
B
Explanation:
Ionic compound can conduct electricity
Answer:
6. protons, mass number from the atomic number
7. Li= ,
Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.
Reaction rate increases with concentration, as described by the rate law and explained by collision theory. As reactant concentration increases, the frequency of collision increases. The rate of gaseous reactions increases with pressure, which is, in fact, equivalent to an increase in concentration of the gas.
Answer:
<h2>The answer is 1.45 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of seawater = 250 g
volume = 173 mL
It's density is
We have the final answer as
<h3>1.45 g/mL</h3>
