The acid dissociation constant or Ka is a value used to measure the strength of a specific acid in solution. For a general dissociation of an acid solution,
HA = H+ + A-
we express Ka as follows:
Ka = [H+] [A-] / [HA]
Where the terms represents the concentrations of the acid and the ions. Assuming that the weak acid in the problem is HA, we first calculate for the concentration of H+ from the pH.
pH = - log [H+]
3.25 = - log [H+]
[H+] = 0.0005623 M
By the ICE table, we can calculate the equilibrium concentrations,
HA = H+ + A-
I 0.175 0 0

E .174438 0.0005623 0.0005623
Ka = (0.0005623) (0.0005623) / .174438
Ka = 1.81x10^-6
So if you put a holo ball of paper in the water it sinks and as it sinks it gets smaller cuse pressure so it cuseus things to shrink cuse of pressure
Around 36 or 37 days, because of the decimal
Valency- it means the combing capacity if an element.
<span> radical- it is an atom, molecule, or ion that has unpaired valence electrons or an open electron shell.

Chemical,when you light a match stick, you are starting a chain reaction of the substance chemical formula, making it a chemical change
