To determine the pH of a solution which has 0.195 M hc2h3o2 and 0.125 M kc2h3o2, we use the ICE table and the acid dissociation constant of hc2h3o2 <span>to determine the concentration of the hydrogen ion present at equilibrium. We do as follows:
HC2H3OO = H+ + </span>C2H3OO-
KC2H3OO = K+ + C2H3OO-
Therefore, the only source of hydrogen ion would be the acid. We use the ICE table,
HC2H3OO H+ C2H3OO-
I 0.195 0 0.125
C -x +x +x
------------------------------------------------------------------
E 0.195-x x 0.125 + x
Ka = <span>1.8*10^-5 = (0.125 + x) (x) / 0.195 -x
x = 2.81x10^-5 M = [H+]
pH = - log [H+]
pH = -log 2.81x10^-5
pH = 4.55
Therefore, the pH of the resulting solution would be 4.55.</span>

Answer:
<h2>The answer is 2.52 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of object = 15.9 g
volume = final volume of water - initial volume of water
volume = 56.3 - 50 = 6.3 mL
It's density is
We have the final answer as
<h3>2.52 g/mL</h3>
Hope this helps you
An airplane flew 3043 km from Houston to Seattle in 5.5 hours. What was the average speed, in m/s rounded to the nearest hundredth, of the airplane from Houston to Seattle?
The answer is 553
C because the average is receipt rate is how quickly
