Consider an experiment in which two burets, Y and Z, are simultaneously draining into a beaker that initially contained 275.0 mL of 0.300 M HCl. Buret Y contains 0.150 M NaOH and buret Z contains 0.250 M KOH. The stoichiometric point in the titration is reached 60.65 minutes after Y and Z were started simultaneously. The total volume in the beaker at the stoichiometric point is 655 mL. Calculate the flow rates of burets Y and Z. Assume the flow rates remain constant during the experiment.
The gas upstream from the point of ammonia injection contains no measurable ammonia. How many kilograms of natural gas are flowing through the pipelines per hour?
Indium antimonide (InSb) is a semiconductor with a narrow band gap of 0.17eV and an intrinsic carrier concentration of 2×1016cm-3. The mobility of electrons in InSb is 78000 cm2/V⋅s and their effective mass is 0.014m0, while the holes have a mobility..

Large blooms of algae result from high nutrient loading in rivers and lakes, for example, as a result of runoff of fertilizers from agricultural fields.
Lowest standard deviation of measurements, As the Quality Control Manager of a chemical company, you are asked to decide between several process methods that are supposed to uniformly mix 37.4 milligrams into a chemical solution.
A piece of hemlock wood measuring 15.15 x 14.8 x 0.75 cm is to be dried from the two large faces from an initial total moisture content of 90% to a final average total moisture content of lo%, with drying taking place in the falling-rate period wi..
Calculating the Maximum Volume of Fermentor that can be used without Additional Cooling, The heat generated by fermentor is 60 kcal/hr L. The cooling capacity of jacket is 10,000 kcal/hr m^2. For a cylindrical fermentor with H/D of 3, the jacket a..
