What happens to the rate of dissolution as the temperature is increased in a gas solution?
Nina [5.8K]

Answer:

The rate decreases

Explanation:

When we dissolve a gas in a water, the process is exothermic. This implies that heat is evolved upon dissolution of a gas in water.

Recall from Le Chateliers principle that for exothermic reactions, an increase in temperature favours the reverse reaction. The implication of these is that when the temperature of the gas is increased, less gas will dissolve in water.

Hence increase in temperature decreases the rate of solubility of a gas in water.

Complete combustion of 2.0 metric tons of coal to gaseous carbon dioxide releases 6.6X10¹⁰ J of heat. Convert this energy to
Jobisdone [24]

6.6 × 10^{10} J = 6.2 × 10^{7} British thermal units

First of all, we should know that 1 British thermal unit = 1055 Joules.

From question, heat = 6.6 × 10^{10} J

1 BTU = 1055 J

6.6 × 10^{10} J = \frac{1}{1055} ×  6.6 × 10^{10} British thermal units

                   = 6.2 × 10^{7} British thermal units

1000 Joules = 1 kilojoule

A kilojoule is a unit of measure of energy, in the equal way that kilometers degree distance. meals energy used to be measured in energy  and some international locations still use those gadgets.

The power we get from foods and drinks is measured in kilojoules. that is the metric time period for calorie. Kilojoules and energy constitute the equal aspect. One calorie is ready four kilojoules.

Calorie a unit for measuring warmth same to the quantity of warmth required to elevate the temperature of one gram of water one diploma Celsius.

If a solution containing A+ ions and a solution containing B- ions have just been mixed and [A+][B-] is greater than Ksp of AB,
frozen [14]

Answer:

Explanation:

In the solution of AB , they are split  to give ions as follows

AB ⇄ A⁺ + B⁻

Product of concentration of A⁺ and B⁻ in saturated solution of AB is constant .

This is called Ksp

Ksp = [A⁺] [ B⁻]

If product of concentration of A⁺  and B⁻ exceeds Ksp , the equilibrium shifts to the left side and excess ions come out of solution in the form of precipitate. So second option is the answer.
