To determine the boiling point (bp), you need this formula---> bp solution= bp solvent + Δbp solution

bp solvent is known since we are dealing with water; it is 100C

all we have to do is to solve for Δbp solution and add it to the 100C. 

Δbp solution= Kb x i x m, where Kb is the constant, i is the number of particles and m is molality. 

Kb= 0.51 
i= 3, K2SO4 ----> 2K+ + SO4-2 (the solute breaks into three ions)
m= ? = moles/kg of solvent

molality (m)= 0.60 mol/ 1.0 Kg= 0.60 m

Δbp solution= 0.51 x 3 x 0.60= 0.918 C

bp solution= 100C + 0.918 C= 100.918 C

How does increased exhalation of CO2 at the lungs (pulmonary regulation) restore the correct pH range?
PilotLPTM [1.2K]

Answer:

When CO2 levels become excessive, a condition known as acidosis occurs. This is defined as the pH of the

blood becoming less than 7.35. The body maintains the balance mainly by using bicarbonate ions in the

blood. As the body responds to neutralize this condition, an electrolyte imbalance – an increase of plasma

chloride, potassium, calcium and sodium, can occur.

What is the solubility of the diazonium salt​
NARA [144]

Answer:

Diazonium salts are salts formed from aromatic primary amines by diazotization. Diazonium salts are not very stable but very reactive. It therefore serves as a starting material for the preparation of various derivatives of arenes, azo dyes and pharmaceuticals.
