Answer:
What happens when electrons in atoms absorb or release energy? When electrons absorb or release energy, their electrons can move to higher or lower energy levels. These electrons lose energy by emitting light when they return to lower energy levels.

Answer:
The van't hoff factor of 0.500m K₂SO₄ will be highest.
Explanation:
Van't Hoff factor was introduced for better understanding of colligative property of a solution.
By definition it is the ratio of actual number of particles or ions or associated molecules formed when a solute is dissolved to the number of particles expected from the mass dissolved.
a) For NaCl the van't Hoff factor is 2
b) For K₂SO₄ the van't Hoff factor is 3 [it will dissociate to give three ions one sulfate ion and two potassium ions]
Out of 0.500m and 0.050m K₂SO₄, the van't hoff factor of 0.500m K₂SO₄ will be more.
c) The van't Hoff factor for glucose is one as it is a non electrolyte and will not dissociate.
The Correct Answer is Eletric Current I think
Explanation:
The number of moles of solute present in liter of solution is defined as molarity.
Mathematically, Molarity =
Also, when number of moles are equal in a solution then the formula will be as follows.
It is given that is 8.00 M, is 7.00 mL, and is 0.80 M.
Hence, calculate the value of using above formula as follows.
= 70 ml
Thus, we can conclude that the volume after dilution is 70 ml.
