Brian is twice as old as Charlie. Three years from now, the sum of their ages will be 33.How old are Brian and Charlie today?

Brian is 18 yr old and Charlie is 9 yr old

Step-by-step explanation:

Let age of Brian be B and that of Charlie be C,

Now,B=2×C and also three years after their ages are B+3 and C+3 respectively

(B+3)+(C+3)=33

Put B=2C

2C+3+C+3=33

3C=27

C=9

Now B=2×9=18

Brian is 18 yr old and Charlie is 9 yr old

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.
