For an arrangement of electrons to be nonpolar in a molecule they need to have equal electron charges.
Explanation:
The attraction between solute particles affect its ability to dissolve in the solution because more is the attraction between particles less will be the chances that solute particles will combine to the solvent particles.
As a result, there will be decrease in solubility with increase in force of attraction between solute particles.
Whereas when there is less force of attraction between solute particles then more easily solute particles will combine with the solvent particles.
Hence, with decrease in force of attraction between solute particles, the rate of dissolution will increase.
Answer:
4. 15
Explanation:
The given formula is:-
1 mole of the salt contains 2 moles of nitrogen atom, 8 moles of hydrogen, 1 mole of sulfur and 4 moles of oxygen atom as can be seen from the formula.
Thus,
1 mole of salt contains total of 15 moles of the atoms which constitute the salt.
<u>Hence, 4. is the answer.</u>
