When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew point temperature is NEVER GREATER than the air temperature. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation.

A mixture of nitrogen and neon gas is compressed from a volume of to a volume of , while the pressure is held constant at . Calc
Mamont248 [21]

Answer:

-266 kJ

Explanation:

There is some info missing. I think this is the original question.

<em>A mixture of nitrogen and neon gas is expanded from a volume of 53.0 L to a volume of 90.0 L, while the pressure is held constant at 71.0 atm. Calculate the work done on the gas mixture. Be sure your answer has the correct sign (positive or negative) and the correct number of significant digits.</em>

<em />

Given data

Initial volume = 53.0 L

Final volume = 90.0 L

Pressure = 71.0 atm

We can find the work (w) associated with the expansion of the gaseous mixture using the following expression.

w = - P × ΔV = - 71.0 atm × (90.0 L - 53.0 L) = -2.63 × 10³ atm . L

w = -2.63 × 10³ atm . L × (101.3 J/ 1 atm . L) = -2.66 × 10⁵ J = -266 kJ

The negative sign means that the system does work on the surroundings.

The balanced equation below represents the decomposition of potassium chlorate.
dezoksy [38]
The oxidation number of chlorine in the reactant can be determined by K ion and O ion. K ion is +1 and O ion is -2. And the Cl is +5. The gas has the greatest entropy and the solid has the least. In the production, there are solid and gas. So it has more entropy than the reactants with solid only.
