The ionic equation is simply:
HCN --> H+
+ CN-
Therefore the formula for Ka is:
Ka = [H+] [CN-]
/ [HCN] <span>
[H+] = [CN-] = x
4.9 x 10^-10 = x^2 / 0.023
x^2 = 1.127 x 10^-11
x = 3.357 x 10^-6 = [H+] = [CN-]
pH = -log [H+]
pH = -log 3.357 x 10^-6
<span>pH = 5.47 </span></span>
I think is False! Because it is not example of a disaccharide it is not saccharin-aspartame molecule.
Metallic bonds result when electrons are shared equally.
The density of marble is between 2.6 and 2.8 grams per cm³ .
Density doesn't depend on how much mass or volume of it you have.
The density of a chip of it is the same as the density of a truckload of it.
