Consider the equations below. (1) Fe2O3(s) - 2Fe(s) + CO2(g) 2 ) (2) Fe2O3(s) + 3CO(g) - 2Fe(s)+3CO2(g) Which equation must be added to equation (1) to produce equation (2)? CO(g) + O2(g) = C020) 3CO2(g) → 300[g)+302(0) g (+ 3CO( 300(g)+202/9) >3002(0) 3 of 8 w A RL

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.
