Astudent needs to determine the volume occupied by a gas in a 125 ml flask using the experimental setup described in the procedure. the student measures the volume of the flask to be 152 ml to the top of the flask. the student measures the volume of the flask with a stopper in it to be 131 ml. the student performs the experiment by reacting the strip of magnesium with 5 ml of hcl solution. what is the volume of the flask occupied by the hydrogen gas?

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
