What is 4(r-9s) +6(r+2s) simplified

7r-24s

Step-by-step explanation:

4(r-9s)+6(r+2s)

Distribute the 4: 4r-36s+6(r+2s)

Distribute the 6:r- 36s+6r+12s

Combine like-terms: 7r-24s

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.
