From the following chemical reactions determine the relative bronsted-lowry acid strengths (strongest to weakest). hclo4(sol) + ch3cooh(l) → ch3c2(oh)2+(sol) + clo4-(aq) h2so4(sol) + ch3cooh(l) < ===> ch3c(oh)2+(sol) + hso4-(sol)

Why is the vapor pressure of a warm lake higher than the vapor pressure of a cold lake? o a. warm water has a greater heat of vaporization. ob. warm water evaporates more quickly. cool water evaporates more quickly. od. cool water has a greater heat of vaporization.

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.

What is the ph of a solution that has a hydrogen ion concentration of 1.0 * 10 -9 m?
