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
Answer:
Yes. u can because its easy to tell if an item will sink or float usually by the weight or the width
Explanation:
It will spread out making the sound travel faster then it usually does in the air(i think) let me know if you need help with anything else
The only bond that involves the complete transfer of electrons is ionic bonding.
A metal that does not have much care for its electrons, such as Sodium, Na, is willing to give up its electron more freely. And an atom that really cares about having electrons might be a gas such as chlorine, Cl. The Chlorine atom takes the electron from Sodium, and then the newly formed ions of Na+ and Cl- bond because they have equal and opposite charges and opposites attract. NaCl is formed.
Hydrogen bonds aren’t actually real bonds (I know, the name is deceptive)
Covalent bonds involve the sharing of electrons.
I’m pretty sure metallic bonds is a made-up term.
Good the equation is balanced already
