What fraction would represent the number 3.45

69/2000

Step-by-step explanation:

3.45/1 x 1/100 x 100/100 = 345/ 10000 = 5 x 69/5 x 2000 = 69/2000                                                        

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.

a negative exponent is translated as follows:

so, we have
