Chemistry
1 answer:
erik [133]3 years ago
7 0

Answer: pH = 2.68

Explanation: pH = - log[H3O^+] .

 HCl reacts with water : HCl + H2O ->  Cl^- + H3O^+

So [H3O^+] = c(HCl) = 0.0021 M

pH = - log(0.0021) = 2.68

Titanium(IV) chloride decomposes to form titanium and chlorine, like this:
Lesechka [4]

The full question is shown in the image attached to this answer

Answer:

6.2 * 10^-3

Explanation:

The reaction at equilibrium is as follows;

TiCl4(l) → Ti(s)+ 2Cl2(g)

We have to obtain the concentration of chlorine gas as follows;

[Cl2] = 1.08/70.91 g/mol × 5.2 L

[Cl2] = 0.079 M

Kc = [Cl2]^2

Kc = [ 0.079]^2

Kc = 6.2 * 10^-3
