Answer:

The number of liters) the boy exhales is 0.499744 liters

Explanation:

The given parameters of how the boy breathes;

The number of moles of gas the boy exhales, n = 0.02231 moles

The condition in which the boy exhales the gas = STP = Standard Temperature and Pressure

The molar volume of a gas at STP, $V_m$ = 22.4 L per mole

Therefore, the volume of gas the boy exhales, 'V', is give as follows;

V = n × $V_m$

By substituting the known values, we have;

V = 0.02231 moles × 22.4 L/mole = 0.499744 L

The volume of gas (the number of liters) the boy exhales, V = 0.499744 L.

A buffer is composed of nh3 and nh4cl. How would this buffer solution control the ph of a solution when a small amount of a stro

Shkiper50 [21]

Answer:

According to Le-chatelier principle, equilibrium will shift towards left to minimize concentration of $OH^{-}$ and keep same equilibrium constant

Explanation:

In this buffer following equilibrium exists -

$NH_{3}(aq.)+H_{2}O(l)\rightleftharpoons NH_{4}^{+}(aq.)+OH^{-}(aq.)$

So, $OH^{-}$ is involved in the above equilibrium.

When a strong base is added to this buffer, then concentration of $OH^{-}$ increases. Hence, according to Le-chatelier principle, above equilibrium will shift towards left to minimize concentration of $OH^{-}$ and keep same equilibrium constant.

Therefore excess amount of $OH^{-}$ combines with $NH_{4}^{+}$ to produce ammonia and water. So, effect of addition of strong base on pH of buffer gets minimized.
