PLEASE ANSWER ALL I WILL RATE 5 STARS MARK BRAINLIEST AND THANK YOU

See below.

Step-by-step explanation:

13. D

Simply subtract. 85376 - 37793 = 47583.

14. C

[Something] - 32497 = 26348

Add 32497 to both sides:

[Something] - 32497 + 32497 = 26438 + 32497

[Something] = 58845

15. C

Compute each difference:

A: 51455 - 26478 = 24977

B: 49351 - 15274 = 34077

C: 63286 - 37439 = 25847

(D: 46307 - 21550 = 24757)

16. B

Simply subtract:

143864 - 112955 = 30909

17. A

First, find the difference:

85732 - 39864 = 45868

Only 45798 (A) is less than 45868.

(Note that B is equal to, not less than).

18. C

Subtract:

45932 - 29574 = 16358.

19. B

Subtract:

96834 - 31727 = 65107 - 12156 = 52951

20. C

27301 - 12352 - [Something] = 7356

14949 - [Something] = 7356

Add [Something] to each side:

14949 = 7356 + [Something]

Subtract 7356 from each side.

7593 = [Something]

Note: Do you need help with subtraction specifically? These questions can be solved with simply with a calculator, but perhaps that is not the intention here. Anyways, I recommend using Khan Academy to improve your arithmetic skills if necesary.

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.

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
