Dude, writing someone else’s story or essay isn’t allowed, so i’ll just give some pointers
so the dude on the throne, a monarch, most likely the king, has a diamond or some other precious object in his hand. meanwhile, there’s a dude sitting on the floor, he looks unhappy, distressed, and maybe a little surprised. so what do you think happened to get to this point? what or who gave the king the diamond? why is the dude on the floor upset? then what’s going to happen? what’s the upset dude gonna
do? what’s the king gonna do? think of answers to the questions and it should start to form
A.
Begin numbering at the end closest to the first branch, not the farthest.
<span>To determine the pH of the solution given, we make
use of the acid equilibrium constant (Ka) given. It is the ratio of the
equilibrium concentrations of the dissociated ions and the acid. The
dissociation reaction of the CH3COOH acid would be as follows:
</span>CH3COOH = CH3COO- + H+<span>
The acid equilibrum constant would be expressed as follows:
Ka = [H+][</span>CH3COO-] / [CH3COOH] = 1.8× 10^–5
<span>
To determine the equilibrium concentrations we use the ICE table,
CH3COOH H+ </span>CH3COO<span>-
I 1.60 0 0
C -x +x +x
----------------------------------------------------------------
E 1.60-x x x
</span>1.8× 10^–5 = [H+][CH3COO-] / [CH3COOH] <span>
1.8 x 10^-5 = [x][x] / [0.160-x] </span>
Solving for x,
x = 1.69x10^-3 = [H+] = [F-]
pH = -log [H+] = -log [1.69x10^-3] = 2.8
It is 3 moles. Don't doubt urself
I'm actually not sure... but maybe this will help!
