Explain why water-soluble oils of low volatility are not typically isolated by steam distillation.
The temperature in the room was 25.0 ºC. James was asked to transfer 4.50 mL of a liquid (density = 0.895 g/mL at 25.0 ºC) using a buret. He added the liquid into a 50-mL beaker weighing 25.789 g. He weighed the beaker with the liquid and found th..
If the methane contained in 4.00 of a saturated solution at 25 was extracted and placed under STP conditions, what volume would it occupy?
what maximum volume of a buffer with a ph=4.58 can be prepared using only these two resources?
calculate the heat in joules released by the dissolving salt. Assume that the specific heat of the solution is the same as thar of pure water(4.184J/g- celcius) and that the calorimeter is perfect.
Clearly indicate coordinate system used in finding the answer. Basically trying to work up to building the molecular orbital diagram. I am stuck in the step where you determine the transformation sequences of each symmetry subset.
Why does the same amount of liquid when left in a wider and flatter container evaporate quicker than when left in a narrower and deeper container?
Vanadium crystallizes in a body centered cubic lattice (the V atoms occupy only the lattice points). How many V atoms are present in a unit cell?
How many grams of copper are in the necklace? 3. If 18-karat gold has a density of 15.5 , what is the volume in cubic centimeters?
Consider a glass of 254 mL of water at 25°C. Calculate the mass of ice at -15°C that must be added to cool the water to 10°C after thermal equilibrium is achieved.
How many quartz of ethylene glycol, C2H6O2 (density = 1.116 g/mL). Will have to be added to 5 gal of water (density = 1 g/mL) to protect an automobile radiator down to a temperature of-10 oF?
Calculate the solubility of zinc hydroxide, Zn(OH)2, in 1.00 M NaOH. Ksp = 3.0 × 10-16 for Zn(OH)2, Kf = 3.0 × 1015 for Zn(OH)42-
how many grams of zinc must react with sulfuric acid in order to obtain 500mL of hydrogen at 20 deg c and 770 mm hg?
