AlekseyPX

Answer:

Reaction will move rightwards.

Explanation:

Hello there!

In this case, according to the proposed question, it turns out possible for us to  figure out the effect of the addition of silver nitrate, by using the following representative equation for the formation of the silver chloride precipitate:

Ag^+(aq)+Cl^-(aq)\rightleftharpoons AgCl(s)

Now, due to the addition of silver nitrate, we will be actually adding silver ions to the solution, which means that, in terms of the Le Ch atelier's principle, the reaction will shift to the right towards the formation of more silver chloride precipitate.

Best regards!

nadezda [96]
The differential pressure is
797.9 - 715.7 = 82.2 torr = 138815.25 Pa
The height of the mercury in the open-end arm is calculated using
ΔP = ρgh
The density of mercury is 13560 kg/m3
The height of the mercury is
138815.25 Pa = 13560 kg/m3 (9.81 m/s2) h
h = 1.04 m
