Achemical reaction has an equilibrium constant of 2*10^6. if this reaction is at equilbrium, select the one corect conclusion that can be made about the reaction.

the forward and back reactions have stopped.
the limiting reactant has been used up.
the forward and reverse rate constants are equal.
the forward and reverse reaction rates are equal.
none of the above conclusions is correct.

Determine which intermolecular forces are the dominant (strongest) forces for a pure sample of each of the following molecules by placing the molecules into the correct bins. drag the appropriate molecular formula to their respective bins.

What is the percentage of hydrogen in nitrogen trihydride

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.
