Answer:
53.18 gL⁻¹
Explanation:
Given that:
------equation (1)
where;
Formation Constant
However, the Dissociation of
yields:
⇄
-------------- equation (2)
where;
the Solubility Constant

From equation (1);
--------- equation (3)
From equation (2)
--------- equation (4)
In
, the net reaction for
can be illustrated as:
⇄

The equilibrium constant (K) can be written as :

![\frac{[[Cu(NH_3)_2]^+][Br^-]}{[NH_3]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B%5BCu%28NH_3%29_2%5D%5E%2B%5D%5BBr%5E-%5D%7D%7B%5BNH_3%5D%5E2%7D)
If we multiply both the numerator and the denominator with
; we have:

![\frac{[[Cu(NH_3)_2]^+][Br^-]}{[NH_3]^2}*\frac{[Cu^+]}{[Cu^+]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B%5BCu%28NH_3%29_2%5D%5E%2B%5D%5BBr%5E-%5D%7D%7B%5BNH_3%5D%5E2%7D%2A%5Cfrac%7B%5BCu%5E%2B%5D%7D%7B%5BCu%5E%2B%5D%7D)

![\frac{[[Cu(NH_3)_2]^+}{[NH_3]^2[Cu^+]}*{[Cu^+][Br^-]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B%5BCu%28NH_3%29_2%5D%5E%2B%7D%7B%5BNH_3%5D%5E2%5BCu%5E%2B%5D%7D%2A%7B%5BCu%5E%2B%5D%5BBr%5E-%5D%7D)



≅ 
Now; we can re-write our equilibrium constant again as:

![\frac{[[Cu(NH_3)_2]^+][Br^-]}{[NH_3]^2}](https://tex.z-dn.net/?f=%5Cfrac%7B%5B%5BCu%28NH_3%29_2%5D%5E%2B%5D%5BBr%5E-%5D%7D%7B%5BNH_3%5D%5E2%7D)



By finding the square of both sides, we have








In gL⁻¹; the solubility of
in 0.76 M
solution will be:

= 53.18 gL⁻¹
Answer:
Weather is describes as the term of the temperature, humidity, wind velocity, precipitation, and barometric pressure. It usually happens in the troposphere, or lower atmosphere. (Hope this helped!)
Explanation:
Depends on the grade of the test. But for the most part if it’s below a 78, it’ll drop, If it’s above it’ll raise. It shouldn’t drop or raise it more than 3 point/percent.
Answer: The process is diffusion.
Explanation:
a dark liquid will have the highest concentration of dark purple atoms/molecules so it gives a concentrated colour.
when water is added to it, the colourless water molecules fill up the gaps between the purple particles and so their colour fades and becomes lighter and lighter as we add more water. see the image attached where imagine the red particles are water and the blue particles are purple particles. thats why the colour fades.
Atoms that have lost or gained one or more electrons are called ions.
