Hydration of alkynes (via oxymercuration) gives good yields of single compounds only with symmetrical or terminal alkynes. Draw the major organic product(s) formed when hex-2-yne undergoes hydration in the presence of HgSO4 and H2SO4.
The nitrate ion (NO3-) is a very poor nucleophile. In fact, solvents such as water or methanol (also weak nucleophiles) are more reactive nucleophiles than the nitrate ion
A saturated solution of calcium iodate, Ca(IO3)2, is created by suspending a small amount of pure solid of Ca(IO3)2 in 50.0 mL of distilled water.
below, 8.34 atm each of H2 and Br2 were placed into a 1.00 L flask and allowed to react: H2(g) + Br2(g) 2 HBr(g) Given that Kc = 86.7, calculate the equilibrium pressure of Br2.
In the welding shop of the XYZ Manufacturing plant you have a cylinder with a volume of 548L of a compressed gas, and the pressure gauge shows 238 psig at the room temperature 25 C.
Predict the precipitate that forms when aqueous solutions of silver nitrate and potassium chloride react to form products in a double-replacement reaction. Include a discussion of how to write the complete chemical equation describing this reactio..
Decide whether or not each of the following metals dissolves in 1 {rm M} {rm HCl}. For these metals that do dissolve, write a balanced redox reaction showing what happens when the metal dissolves.
What is the pH when 100 mL of 0.1 M HCl is titrated with 50 mL of 0.2 M NaOH?
A gas is heated from 14 degrees celsius to 121 degrees celsius and the volume increased from 15.0 liters to 41.4 liters. If the original pressure is 1 atm, what would the final pressure be?
Calculate the pressure inside the graduated cylinder it the height of the water is 5mm higher than the water in the trough. The atmospheric pressure is 760 mm Hg
Phosphorous trichloride (PCl3) is produced from the reaction of white phosphorous (P4) and chlorine: P4(s) + 6 Cl2(g) → 4 PCl3(g) . A sample of PCl3 of mass 298 g was collected from the reaction of 75.37 g of P4 with excess chlorine.
The electron in the n = 5 level of a hydrogen atom emits a photon with a wavelength of 1280 nm. To what energy level does the electron move?
A sample of neon gas is held in a rigid 1.814L container with a pressure of 1.273atm at 25 C. 3.193g of an unknown gas is added to the container. The temperature remains constant, but the pressure rises to 2.386atm. What is the molar mass of the a..
