B. hydrogen sulfide, h2s, is a contaminant in natural gas. it can be removed with the reaction ch4(g) + 2h2s(g) cs2(g) + 4h2(g), δh = 232 kj/mol. how should the following conditions of this reaction be changed to optimize the removal of h2s? explain your answers.
i. changing the pressure
ii. changing the temperature
iii. changing the h2 concentration

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.
