explain the difference between (-10)^2 and -10^2.

(-10)² is 100 and -10² is -100

Step-by-step explanation:

The parentheses in (-10) means you're multiplying -10 and -10 which gives you 100. -10² means you're multiplying 10 and 10 which is 100, but you have the negative sign still so you add the negative sign to the 100 which makes it -100. Hope it helped (:  

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.

-1/2 +2
