7^2 + 1 - 5 x 3 where do the parenthesis go if the value is 135

(7²+(1-5))×3=

Step-by-step explanation:

Let's try this

(7²+(1-5))×3=

(49-4)×3=

45×3=

135

(Worked first try :o!)

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.
