Afuel oil is analyzed and found to contain 86.14 wt% carbon, 11.12% elemental hydrogen (h), 1.90% sulfur, and the remainder noncombustible matter. the oil is burned with 7.5% excess air, based on complete combustion of the carbon to co2, the hydrogen to h2o, and the sulfur to so2. the oil is burned completely, but 6.50% of the carbon forms co. calculate the molar composition of the stack gas. you may take the composition of air to be 79.0 mole% n2 and 21.0 mole% o2.

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.
