What is the correct defination for carbon tetrachloride

1 answer:

5 0

B - CCL4

This is because it doesn't say Dicarbon or any of that sort, so Carbon is alone. This immediately eiminates the option of C.

A is incorrect as it has Chlorine first rather than Carbon, so that's also incorrect.

D is incorrect as 7 is hepta rather than tetra.

The list is as so;

Mono - 1; Di - 2; Tri - 3; Tetra - 4; Penta - 5; Hexa - 6; Hepta - 7; Octa - 8; Nona - 9; Deca - 10.

Hope this helps!

A mysterious compoud with the chemical formula MX (Ksp 1.27x10-36) is present in two different solutions. What is its molar solu

qwelly [4]

Answer: The molar solubility of MX is $2.54\times 10^{-36}M$

Explanation:

We are given:

$K_{sp}(MX)=1.27\times 10^{-36}$

The chemical equation for the ionization of MX follows:

$MX\rightleftharpoons M^+(aq.)+X^-(aq.)$

S S

The expression of $K_{sp}$ for above equation is:

$K_{sp}=S\times S$ ......(1)

The chemical equation for the ionization of $M_2SO_4$ follows:

$M_2SO_4\rightleftharpoons 2M^+(aq.)+SO_4^{2-}(aq.)$

0.25M 0.5M 0.25M

Total concentration of cation from both the equation is:

$[M^+]=0.5+S$

As, $K_{sp}(MX)$ , so S is also very very less than 1 and can be easily neglected.

So, $[M^+]=0.5M$

Putting values in equation 1, we get:

$1.27\times 10^{-36}=0.5\times S\\\\S=2.54\times 10^{-36}M$

Hence, the molar solubility of MX is $2.54\times 10^{-36}M$
