Find δe for the change in state of 1.0 molh2o(l) at 79 ∘c to h2o(g) at 116 ∘c. the heat capacity of h2o(l) = 75.3 j/molk, heat capacity of h2o(g) = 25.0 j/molk, and the heat of vaporization of h2o is 40.7×103j/mol at 100 ∘c.

Acylinder is filled with 2.00 moles of nitrogen, 3.00 moles of argon and 5.00 moles of helium. if the gas mixture is at stp, what is the partial pressure of the argon

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.
