Estimate the sum of the numbers

236
+659

236 + 659 ≈ 900

Step-by-step explanation: First, let's round 236 to the nearest tenth place. Since the last number is 6 and is closer to 40 than to 30, let's round it to 240.

Next, let's round 659. The last number is 9, which is closer to 60 than to 50. So, 659 rounded to the nearest tenth is 660.

Now all we have to do is add the two rounded numbers. 240 + 660 = 900

So, 236 + 659 ≈ 900

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.
