Organize each of the subsequent reactions as a combination, decomposition, single displacement, or double displacement. Define
a. CuO + 2 HCl ->CuCl2 + H2O
b. 2 Al + 3 Br2 -> 2 AlBr3
Determine what will be the major product expected from chronological treatment of propylbenzene with 1) KMnO 4 , 2) 3)H 3 O + , Cl 2 and FeCl 3 , and iv) Br 2 and FeBr 3 ?
calculate the heat of reaction for 2PbS +3O2 yields 2PbO +2SO2 given the following information. PbS= -93.3 kj/mol. PbO=-219.7. SO2=-296.6. O2 = 0. I got -846kj, is that correct
A 0.1236-g sample of an unknown monoprotic acid was dissolved in 25.8 mL of water and titrated with 0.0680 M NaOH solution. The volume of base required to bring the solution to the equivalence point was 19.1 mL.
Write a "mechanism" for the formation of phenacetin from acetaminophen and ethyliodide.
A 0.7549g sample of a pure hydrocarbon burns in oxygen gas to produce 1.9061g of carbon dioxide and 0.3370g of water.
What weight of A would be removed from the same solution by successive extraction with four portions of 25mL of hexanes? How much hexanes would be required to remove 98.5% of A in single extraction?
What component of air will bring about this reaction and what is its approximate concentration in air? If you had a stoppered flask with basic luminol and then opened it to the air
Can solution color be predicted from the Absorbance wavelength max or Transmission wavelength max color(s). Aluminum nitrate. Cadmium nitrate
A chemical plant produces an ammonia-rich waste gas that cannot be released as-is into the environment. One method to reduce the ammonia concentration in the waste gas is to bubble the waste gas through a liquid solvent.
When 4.00g of hydrogen nuclei fuse to form helium in the sun, 0.0265g of matter is converted into energy. Given that the speed of light = 3.00x10^8 m/s and that a jolue = kg*m^2/s^2, calculate how much energy is given off.
Cyclohexene with potassium permanganate solution. Cyclohexene with bromine-water solution
