Answer:
the solubility of the ionic solid decreases
Explanation:
If a salt MX is added to an aqueous solution containing the solute AX, the X^- ion is common to both of the salts. The presence of X^- in the solution will suppress the dissolution of AX compared to the solubility of AX in pure water. This observation is known as common ion effect in chemistry.
The origin of common ion effect is based on Le Chatelier's principle. The addition of a solute will drive the equilibrium position towards the left hand side.

Answer:
180.87 °C
Explanation:
Applying pressure law,
P/T = P'/T'..................... Equation 1
Where P = Initial pressure of helium gas, T = Initial Temperature of helium gas, P' = Final Pressure of helium gas, T' = Final Temperature of helium gas
Make T' the subject of equation 1
T' = P'T/P......................... Equation 2
From the question,
Given: P = 1.5 atm, P' = 2.3 atm, T = 23°C = (23+273)K = 296 K
Substitute these values into equation 2
T' = (2.3×296/1.5)
T' = 680.8/1.5
T' = 453.87 K
T' = 453.87-273
T' = 180.87°C
Group 14: Carbon family has valence electrons.
Answer:
Explanation:
Hello!
In this case, for the undergoing chemical reaction at equilibrium:
Which means that pressure-based equilibrium constant is computed via the following equilibrium expression:
Thus, by plugging in the given pressures at equilibrium, the required Kp turns out:
