Which number is an irrational number?
a.-22/9
b .-√3
c.2.56
d.√16

Option B is irrational            

Step-by-step explanation:

Given 4 options, we have to choose the option which is an irrational number .

An irrational number is a number that can't be expressed as a fraction or in form of , where q≠0. They have decimal expansions that neither terminate nor become periodic i.e non-terminating non-repeating.

Option A:

which is non-terminating but repeating

∴ can be expressed in form of .

Hence, rational

Option B:

The above is non-repeating and non-terminating.

⇒ irrational number

Option 3:

shows can be expressed as a fraction or in form of

hence, rational.

Option 4:

shows can be expressed as a fraction or in form of

hence, rational number

Option B is irrational.

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.
