31. A mixture with sand, pink sugar and water would be best separated using

ozzi

Answer:

Filtration and evaporation

Explanation:

A mixture of sand, pink sugar and water can be separated by filtration and evaporation.

The pink sugar is already dissolved in the water but the sand remains undissolved in the water hence it can be filtered off. The filtrate now contains the sugar.

The sugar is obtained from the filtrate by evaporation of the solution to yield the solid pink sugar and steam which can be condensed again to give liquid water.

In a chamber filled with air (look up the partial pressures of nitrogen and oxygen gases) at 2200 °C, the reaction that generate

Lelechka [254]

Answer: The equilibrium partial pressure of nitrogen gas, oxygen gas and nitrogen dioxide are 0.7934 atm, 0.1668 atm and 0.0332 atm respectively.

Explanation:

We know that:

Partial pressure of nitrogen gas at 2200°C = 0.81 atm

Partial pressure of oxygen gas at 2200°C = 0.20 atm

The chemical equation for the formation of nitrogen dioxide follows:

$N_2(g)+2O_2(g)\rightleftharpoons 2NO_2(g)$

Initial: 0.81 0.20

At eqllm: 0.81-x 0.20-2x 2x

The expression of $K_p$ for above equation follows:

$K_p=\frac{(p_{NO_2})^2}{(p_{O_2})^2\times p_{N_2}}$

We are given:

$K_p=0.050$

Putting values in above equation, we get:

$0.050=\frac{(2x)^2}{(0.20-2x)^2\times (0.81-x)}\\\\x=-18.98,-0.0256,0.0166$

Neglecting the negative value of 'x' because partial pressure cannot be negative

So, equilibrium partial pressure of nitrogen dioxide = 2x = 2(0.0166) = 0.0332 atm

Equilibrium partial pressure of nitrogen gas = (0.81 - x) = (0.81 - 0.0166) = 0.7934 atm

Equilibrium partial pressure of oxygen gas = (0.20 - 2x) = [0.20 - 2(0.0166)] = 0.1668 atm

Hence, the equilibrium partial pressure of nitrogen gas, oxygen gas and nitrogen dioxide are 0.7934 atm, 0.1668 atm and 0.0332 atm respectively.
