Answer: maybe D sorry if it's wrong
Explanation:
Answer:
Perfectly Specified
Explanation:
Given,
Pressure = P = 0.9 atm
and the Boiling point = T
Number of phases P = 1
Number of components C = 1
According to Gibb's phase rule ,
F = C - P + 2
If
- F = 0, the system is perfectly specified
- F > 0, the system is under specified
- F < 0 the system is over specified
At P = 0.9 atm, boiling point is T i.e. Fixed equal to 96.7 °C (from steam table)
P is independent variable and T is dependent variable (depends on the value of P ).
In this case only two variables are required to fix the system pressure and temperature.
In the given problem, pressure is fixed so the temperature is also fixed. There is no requirement of any other variable.
Therefore degree of freedom,
F = 0
The system is perfectly specified.
Answer:
2
Explanation:
In the equation, Cl is chlorine and there is a number "2" so that the correct answer is 2.
Maybe her old shoes had soft worn out bottoms and she slips in them. So her new shoes had more grip than her old ones so they kept her from falling.
Answer:
Explanation has been given below.
Explanation:
Let's consider solubility equilibrium of an ionic insoluble compound e.g. 
Equilibrium constant of this solubility equilibrium is represented in terms of solubility product (
) which is expressed as-
![K_{sp}=[Ba^{2+}][SO_{4}^{2-}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BBa%5E%7B2%2B%7D%5D%5BSO_%7B4%7D%5E%7B2-%7D%5D)
Now, if we add an ionic salt e.g. 
with a common ion 
then concentration of increases.
But, at a constant temperature, is constant.
Therefore, to keep constant, excess amount of will combine with free 
ion in solution and produce .
Hence, as a whole, solubility of decreases.
