Hydrazoic acid, HN3, has a K, value of 1.9 x 10-5. If you prepare a 0.470 M solution of HN3, answer each of the questions listed below. a) Based on the information provided above, fill in the ICE table below inputting x for any relative changes. Be sure to indicate the direction of change, i.e. +/-. Be sure to use the proper number of significant figures. Any zeroes should be denoted as 0. The equilibrium row should contain the x variable.
