Mario is planning a charity dinner. each table costs $50 and each chair costs $7 to rent. the other costs of the dinner are $475. let trepresent the number of tables and let c represent the number of chairs. which of the following expressions represents the total cost of the dinner?

a. t + c + 475

b. 50t + 7c = 475

c. 7t + 50c + 475

d. 50t + 7c + 475

D. 50t + 7c + 475

Step-by-step explanation:

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.
