The beaker contains four liquids of different densities. The blocks in the beaker represent four different solid materials. The table below shows the densities of the four solid materials. Based on the densities of the solid materials and the densities of the liquids, which type of solid material is Block C?

What are the concentrations of hydroxide and hydronium ions in a solution with a ph of 10.2?

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.
