A tributary and a distributary are both bodies of freshwater that eventually meet with or diverge from rivers, but they differ in the direction that they flow. A tributary is a stream that flows into a larger river. A distributary is a stream or small river that splits off from a larger river and flows in a different direction.

Argon makes up 0.93% by volume of air. Calculate its solubility (in mol/L) in water at 20°C and 1.0 atm. The Henry's law constan

ivolga24 [154]

Answer : The solubility is, $1.4\times 10^{-5}mol/L$

Explanation : Given,

$k_H$ = Henry's law constant of argon = $1.5\times 10^{-3}mol/L.atm$

First we have to calculate the pressure of argon.

Pressure of argon = $1.0atm\times \frac{0.93}{100}$

Pressure of argon = 0.0093 atm

Now we have to calculate the solubility.

As, the solubility of argon in 1 atm pressure = $1.5\times 10^{-3}mol/L$

So, the solubility of argon in 0.0093 atm pressure = $\frac{0.0093atm}{1atm}\times 1.5\times 10^{-3}mol/L$

= $1.4\times 10^{-5}mol/L$

Thus, the solubility is, $1.4\times 10^{-5}mol/L$

Which of the following is a diprotic acid? a. H2SO4 b. CH3COOH c. HC d. H3PO4

RUDIKE [14]

Answer:

The correct option is: A. H₂SO₄

Explanation:

Acid is a charged or a neutral molecule that is a proton donor and electron pair acceptors.

Acids can be classified into monoprotic acids and polyprotic acids.

Monoprotic acids are the acids that can release only one proton on dissociation.

Whereas, polyprotic acids are the acids that can release more than one proton on dissociation.

Diprotic acid is a type of polyprotic acid that can release two protons on dissociation. Example: H₂SO₄
