Answer:
Kb is termed as Ebullioscopic constant.
Explanation:
According to Boiling point elevation phenomenon, any solution will be exhibiting higher boiling point compared to its pure solvent. So this increase in the boiling point of any liquid when a solute is added in the host is termed as boiling point elevation phenomenon. Thus, the boiling point elevation should be related with the molality of the solution b . So the ratio of increase in the boiling point or the boiling point elevation temperature to the molality of the solution gives a constant termed as ebullioscopic constant and denoted as Kb. In other words, we can state the boiling point elevation temperature is directly proportional to the molality of solution with Kb as proportionality constant.

Answer:
Option (D)
Explanation:
Phosphorylation can be simply defined as the addition of a phosphate group to an organic and inorganic molecule. This process helps in regulating the processes that occur in the cells. It leads to the growth and development of cells and this process is efficiently carried out with the help of enzymes like kinase. It also plays an important role in transferring the signals within the cells, synthesis, and functioning of proteins within the cells, and storing as well as releasing of energy.
Thus, the correct answer is option (D).
Answer:
It increases.
When the frequency of electromagnetic waves increases, the wavelengths also increase because the frequency sends power to the wavelengths.
100.0ml*0.400m =xml *2.00m
x=100.0*0.400/2.00= 20 ml 2.0 m CaCl2
you need to take 20 ml 2.0 m CaCl2 and dilute it with water up to 100.0 ml
