Calculate the volume of 1.0 x 10-4 M CV+ solution that needs to be added to a 25.0 mL volumetric flask and diluted with deionized (DI) water in order to prepare a calibration standard solution with a concentration of 1.0 x 10-5 M CV+.
The infrared spectrum of CH3CH2NH2 shows two absorptions not shwon by bromoethane. Identify the bonds responsible for these two absorptions.
H2 reacts according to the following equation representing the synthesis pf ammonia gas: N2(g) + 3H2(g)--> 2NH3 If 1 Liter of H2 is consumed, what volume of ammonia will be produced at constant temperature and pressure
how many grams of iron will react with water to form iron (III)oxide and 85 liters of hydrogen gas at 19 degrees celsius & 525 torr?
where it is burned with 12% excess air. Calculate the required flow rate of air in SCMH(standard cubic meters per hour).
suggest a procedure you could follow to determine whether it was necessary to use this solution as a reference or whether distilled water would have been just as satifactory
What would you expect to happen to the sizes of these bubbles if they were connected with a tube without bursting either bubble?
Combine the above two equations with that for the formation of liquid water and use addition and/or subtraction(i.e. Hess's Law) to arrive at the equation for the formation of magnesium oxide.
how would each affect the calculated molecular mass of the solute?
Caffeine is made up of 49.5% C, 5.2% H, 16.5%O, and 28.9% N. A solution made up of 8.25g of caffeine and 100.0 of benzene (d=0.887g/ml) freezes at 3.03C.
What is the pH of a solution containing 0.24 moles of ammonia and 17.8g of ammonium chloride, NH4Cl. Kb for ammonia is 1.8 times 10, What is the PH of a 0.085M solution of ammoniun chloride. Kb for ammonia is 1.8 times 10
Rank the fluorine species from most to least stable. To rank items as equivalent, overlap them.
A sample of the exit air is drawn in to a chamber containing a mirror and cooled slowly, keeping the gauge pressure at 10mm Hg. A mist is observed to form on the mirror at a temperature 40C. Calculate mass of water removed from ..
