The combustion of ethane (c2h6)(c2h6) produces carbon dioxide and steam. 2c2h6(g)+7o2(g)⟶4co2(g)+6h2o(g) 2c2h6(g)+7o2(g)⟶4co2(g)+6h2o(g) how many moles of co2co2 are produced when 5.95 mol5.95 mol of ethane is burned in an excess of oxygen? moles of co2: co2:

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.
