complete and balance the following half equations for this reaction between chlorine and potassium bromide which is a redox reaction because the bromide ion is oxidised and the chlorine is reduced
__br(aq) → br2(aq) + __
cl2(aq) + 2e →

What is the mass of 0.46 mil of mgcl2

The element that has the greatest electronegativity is

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.
