Which of the following lists of ordered pairs is a function ?

To be a function, for any X value( input) you can only have one Y(output value).

In A) there are two x values of 2, but each one has a different Y value, so this cannot be a function.

In C, there are two x values of 1, each with a different Y value, so also cannot be a function.

D) has two X values of 0, and each has a different Y value so cannot be a function.

The correct answer would be B.

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.
