Which polynomial lists the powers in descending order?

D

Step-by-step explanation:

D is the only answer choice where the terms in the polynomials are descending in power, or their exponents. The powers are 7, 5, 4, 3, 0. The other answer choices have powers that aren't in descending order.

b

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.
