How do i do -1 1/2 - 2 4/7

Step-by-step explanation://

First you change your fractions to an improper fraction. so -3/2 and 18/7. Then you subtract the top and bottom which is -21/-5. a negative over a negative is a positive so it would be 21/5 then you can change it back to a mixed number. so your answer would be 4 1/5

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.
