What is the limiting reagent when 3.2 mol of SO2 react with 2.2 mol of O2 according to this equation: What is the amount of unreacted excess reagent left over. 2SO2(g) + O2(g) -> 2SO3(g) b. Calculate the maximum amount of product that can be formed in moles and liters of gas-

c. If only 1.2 mol of SO3 gas was produced, then what was the actual yield in liters and what was the percent yield-

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.

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Which of the following are correct values for the ideal gas laws constant r
