Please help meee i’m being timed!!

Step-by-step explanation:

Multiply the given numbers together.

(-5)×(4.2) → -21

(-7)×(-3) → 21

(4 )×(5) → 22.5

(2.5)×(-9) → -22.5

Two negatives make a positive  (negative × negative = positive)

A negative and a positive make a negative (negative × positive = negative)

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.
