Answer:

The concentration of H2CO3 decreases.

Explanation:

Respiration may be defined as the process of exchange of gases between the alveoli, tissues and external environment. The oxygen is inhaled and carbon dioxide is exhaled out during respiration process.

Rapid exhalation of CO2 means the amount of oxygen is more than the carbon dioxide. The concentration of H2CO3 will decrease as less amount of carbon dioxide is available in the body. The concentration of carbon dioxide is directly proportional to the concentration of H2CO3. Hence, the concentration of H2CO3 will decrease.

Thus, the correct answer is option (1).

If there is a constant loss of $CO_{2}~(carbon~dioxide)$ the concentration of $H_{2} CO_{3}~(carbonic~acid)$ will be affected and decrease since $CO_{2}$ is a main component of $H_{2}CO_{3}$ .

Answer:

Hb would be 78.4% saturated.

Explanation:

This problem can be solved by using simple unitary method.

At 100 mm Hg pressure of oxygen, Hb is saturated by 98%

So, at 1 mm Hg pressure of oxygen, Hb is saturated by $\frac{98}{100}$ %

Hence, at 80 mm Hg pressure of oxygen, Hb is saturated by $\frac{98\times 80}{100}$ % or 78.4%

Therefore, at 80 mm Hg pressure of oxygen in the lungs, Hb would be 78.4% saturated.

Answer: It decreases because nonvolatile aluminum and chloride ions now occupy some of the volume of the system.

Explanation:

Vapor pressure of a liquid is defined as the pressure exerted by the vapors in equilibrium with the liquid/solution at a particular temperature.

So, when a non-volatile solute is added to a solvent then its molecules align at the surface of liquid. As a result, less number of solvent molecules will escape from the solution. Thus, there will be decrease in vapors and thus the vapor pressure decrease.

The relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
