Ammonia and preheated air are mixed to form a gas containing 15.0 mol% NH3 at 500°C. If ammonia enters the mixing unit at 30°C at a rate of 600 kg/h and heat is lost from the mixer to its surroundings at a rate of 12.00 kW, determine the temperature to which the air must be preheated.
which of these compounds will be the most polar and which of the compound will have the largest London forces?
A 500ml portion of a solution at pH=13 will just barely dissolve 3.2x10-4 moles of calcium hydroxide. What is the Ksp of calcium hydroxide
at a certain temperature the vapor pressure of pure benzene c6h6 is 0.930 atm. a solution was prepared by dissolving
Choose the selection which gives the correct number of and bonds present in one molecule or ion of ozone, O3. Make the central atom in your Lewis structure follow the octet rule if possible.
Using the accepted ionic radius of the ammonium ion, NH4+, NH4Br is predicted to have a rock-salt structure with (6,6)-coordination. However, at room temperature NH4Br has a cesium-chloride structure. Explain this observation.
Tween-20 is a detergent that is often used in immunological assays. Concentrated Tween-20 a viscous liquid and is difficult to accurately pipette in small amounts. Because of thism it is common to make a 10% stock of Tween 20 i nwater and use this..
Consider the molecules CsO2, Na2O, K2O2, MgO, and H2O2 and answer the questions below. If there is more than one answer, give both separated by a comma with no spaces. Order doesn't matter.
Draw a flow sheet to show how you would separate the components of a mixture containing an acid substance, toluic acid; a basic substance, p-bromo-aniling and a neutral substance, anthracene.
Aspirin (C9H8O4) is produced through the following reaction of salicylic acid (C7H6O3) and acetic anhydride (C4H6O3). C7H6O3(s) + C4H6O3-> C9H8O4(s) + HC2H3O2
22.3 g of a substance x dissolves in enough water to make 0.507 l of a 0.779 m solution. calculate the molar mass of x
An aqueous solution containing 5.85g of an optically pure compound was diluted to 800.0mL with water and placed in a polarimeter tube 10.0cm long. The measured rotation was -5.93degrees at 25degrees C. Calculate the specific rotation of the compou..
Molecules can be as small as a few atoms or as large as thousands of atoms. In 1962, Max F. Prutz and John C. Kendrew were awarded the Nobel Prize for their discovery of the structure of hemoglobin.
