The curve C in the x-y plane is given parametrically by ( x ( t ) , y ( t ) ) , where d x d t = t sin ( 2 t 3 ) and d y d t = cos ( t 2 4 ) for 1 ≤ t ≤ 6 . a. Find the slope of the line tangent to the curve C at the point where t = 3 . b. For 1 ≤ t ≤ 6 , what is the value of t at which the line tangent to the curve C is vertical? c. Find the length of the curve C for 1 ≤ t ≤ 6 .

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.
