$1 \ g$ of silver gets distributed between $10 \ cm^{3}$ of molten zinc and $100 \ cm^{3}$ of molten lead at $800^{\circ} C$. The percentage of silver still left in the lead layer is approximately

$CO_2$ gas is bubbled through water during a soft drink manufacturing process at $298 \ K$. If $CO_2$ exerts a partial pressure of $0.835 \ bar$,then $x \ mmol$ of $CO_2$ would dissolve in $0.9 \ L$ of water. The value of $x$ is $.....$ (Nearest integer).
(Henry's law constant for $CO_2$ at $298 \ K$ is $1.67 \times 10^3 \ bar$)

What is dissolution?

Calculate the solubility of gas in water at $1.2 \text{ atm}$ and $25^{\circ} C$ if Henry's law constant is $0.45 \text{ mol dm}^{-3} \text{ atm}^{-1}$ at $25^{\circ} C$.

The solubility of a gas in a liquid increases with:

When a bottle of soft drink is opened, which of the following phenomena occur?
$(A)$ Solubility of dissolved gas decreases.
$(B)$ The bottle releases internal pressure.
$(C)$ Effervescence is observed from the bottle.
$(D)$ Increase in external pressure.
Identify the correct choice.
