Answer:
1 is the same 3 is pure substance 4 is different
Explanation:
not sure about 2
A saturated solution is a solution that contains a certain amount of solute that is enough to be dissolved in the solvent. Anything above that amount will not dissolve some of the solute in the solvent. When a saturated solution is cooled, the solubility of the solute lowers making the solution supersaturated.
Answer : The lowest numbered energy level where a 'd' sublevel is found is 3.
Explanation : According to the theory of order of electron filling;
The 4s orbitals is observed to have a lower energy than the 3d, and so the 4s orbitals are filled first.
It is known that 4s electrons are lost first during ionisation activity. Therefore, the electrons lost first will come from the highest energy level, furthest from the influence of the nucleus.
So, the lowest energy level where 'd' sub shell will be found is 3d.
