The maximum size of a text message is 160 characters. A space counts as one character. Write an equation that represents the number of remaining (unused) characters in a text message as you type. Let x represent the number of typed characters and r represent the number of remaining characters.

_______________________________

Where r = # remaining characters, and x = # typed characters.

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
