What is 4/5 ( + ) 1/2 + ( 3/4)

41/20

Step-by-step explanation:

Simplify the following:

4/5 + 1/2 + 3/4

Hint: | Put the fractions in 4/5 + 1/2 + 3/4 over a common denominator.

Put 4/5 + 1/2 + 3/4 over the common denominator 20. 4/5 + 1/2 + 3/4 = (4×4)/20 + 10/20 + (5×3)/20:

(4×4)/20 + 10/20 + (5×3)/20

Hint: | Multiply 4 and 4 together.

4×4 = 16:

16/20 + 10/20 + (5×3)/20

Hint: | Multiply 5 and 3 together.

5×3 = 15:

16/20 + 10/20 + 15/20

Hint: | Add the fractions over a common denominator to a single fraction.

16/20 + 10/20 + 15/20 = (16 + 10 + 15)/20:

(16 + 10 + 15)/20

Hint: | Evaluate 16 + 10 + 15 using long addition.

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.
