A mixture of 0.050 mol of 7_1.gif, 0.025 mol of7_2.gif, and 0.050 mol of 7_3.gif is placed in a 1.0-L vessle. The following equilibrium is established: 7_4.gif At equilibrium [NO] = 0.031 M Calculate the equilibrium concentrations of 7_5.gif and 7_6.gif

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
