At 25 degree celsius, what is the hyronium ion concentration in 0.100 M chloroacetate acid?

If we shorten chloroacetic acid to HC, then
..........HC ==> H^+ + C^-
initial...0.100M..0.....0
change.....-x......x.....x
equil....0.100-x....x....x
Ka = (H^+)(C^-)/(HC)
Look up Ka, substitute from the ICE chart above and solve for H^+.
