On the basis of your data what conclusion may be made regarding the separating ablility of simple and fractional distillation? comment on how well your results compare with what might be expected using your actual data below
If 2.61 g of methane gas (CH4) is introduced into an evacuated 1.67 L container at 15°C, what is the pressure in the container?
The standard heat of formation of WO3(s) is -843 KJ/mol, and its standard molar entropy
What is the total mass of AlCl3 in this sample? b. How many moles of AlCl3 are in this sample?
Number of protons & the number of neutrons in the nucleus of the element boron and potassium and the number of electrons in their 1st & 2nd quantum shells?
When the mixture is ignited, gases are produced and 815 J of energy is released. To what volume will the gases expand against a constant pressure of 635 mmHg, if all the energy released is converted to work to push the piston?
A student studied the clock reaction described in this experiment. She set up a reaction mixture by mixing 10mL of 0.010 M KI, 10mL of 0.0010 M Na2S2O3, 20mL of 0.040 M KBrO3 and 10 mL of 0.10 M HCL.
You dissolve 1.00 gram of an unknown diprotic (two titratable protons) acid in 200.0 mL of H2O. This solution is just neutralized by 5.00 mL of a 1.00 M NaOH solution. What is the molar mass of the unknown acid?
If O2 is collected over water at 40.0 Celsius and a total pressure of 737 mmHg, what volume of gas will be collected for the complete reaction of 23.92 g of NiO?
