Explanation:

Buffer solution is a specific type of solution which able to resist the pH change when small amount of acid or base is added to it.There are various buffer system present inside our body that helps to regulate the pH of our body.

     The clinical contidition in which the blood pH is above is 7.45 is called alkalosis it can be overcome by addition of required amount of acid or H+ ion to neutralize to excess base.

  For example during alkalosis the CO2 that is produced during cellular respiration reacts with water to generate carbonic acid(H2CO3) which will help to neutralize the excess base to maintain the normal pH of the blood.

olga_2 [115]

Answer:

4.43L is final volume of the ballon

Explanation:

Avogadro's law of ideal gases states that <em>equal volumes of gases, at the same temperature and pressure, have the same number of molecules</em>.

The formula is:

\frac{V_1}{n_1} =\frac{V_2}{n_2}

Where V and n are volume and moles of the gas in initial and final conditions.

If the initial conditions are 0.0145 moles and 2.54L and final amount of moles is 0.0253moles, final volume is:

\frac{2.54L}{0.0145mol} =\frac{V_2}{0.0253mol}

V₂ = <em>4.43L is final volume of the ballon</em>
