If 0.785 mole of ammonia gas occupies 24.5 L at 0.853 atm, what is the Celcius temperature?
Fortunately, you can narrow the search because the PVC piping comes from unique vendors each with their unique degrees of polymerization. By detailed measurement, you determine that the PVC molecular non-extended (i.e., coiled) length is 7 nm. Wha..
compute the partition coefficient for the compound between C 6 H 14 and H 2 O (Kphexane/water).
The solubility constant of TlBr is Ksp = 3.6 × 10-6 and the solubility constant of AgBr is Ksp = 5.0 × 10-13. Determine the range of NaBr volumes over which each solid precipitates.
Enough of a monoprotic acid is dissolved in water to produce a 0.0189 M solution. The pH of the resulting solution is 6.25. Calculate the Ka for the acid.
When the 400 mL of solution was treated with an excess of 2.00 M sulfuric acid and boiled to remove all the gas in solution, 3.73 L of dry carbon dioxide gas measured at 740 mm Hg and 22 C were obtained. Calculate the molarity of the sodium carbon..

For a particular reaction, deltaH is -93.8kJ and deltaS is -156.1 J/K. Assuming these values change very little with temperature, over what temperature range is the reaction spontaneous in the forward direction?
A 5.00 L volume of ethane gas is heated from 298 K to 596 K. If the pressure remains constant, what is the final volume?
the molecules water and methane have similar masses but methane changes from a gas to a liquid at -161 degrees celsius.
how do you prepare 50mL of 0.15M malonic acid, 0.020M manganese sulfate and 0.5% (w:v) starch from malonic acid CH2(COOH)2 reagent grade, starch (soluble), and manganese (II) sulfate monohydrate, MnSO4.H2O (s)?
The inclined plane is supported by a horizontal table. Both the cube and the inclined plane can move without friction along the surfaces that support them (the inclined plane and the table, respectively). What is the normal force on the inclined p..
