Titanium-51 decays with a half life of 6 minutes. What fraction of titanium have decayed after 18 minutes? HELP PLS DUE IN 15 MINS

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)

Balance this equation co2(g) + h2o (g) show that the balanced equation obeys the law if conversation of mass
