What is oxidized and what is reduced in this reaction? n2h4(l) + 2h2o2(l) → n2(g) + 4h2o(g)
a) n is reduced and h is oxidized.
b) n is reduced and o is oxidized.
c) n is oxidized and o is reduced.
d) n is oxidized and h is reduced.

Calculate the h3o+ concentration in a solution of acetic acid if the concentration of molecular acetic acid present at equilibrium is 9.97x10^-3 m and k for the dissociation is 1.86x10^-5. ch3cooh(aq)+h2o(> h3o^+(aq)+ch3coo^-(aq)
