A compound A has prominent infrared absorptions at 1050, 1786, and 1852 cm-1 and shows a single absorption in the proton NMR spectrum at ? 3.00. When heated gently with methanol, compound B, C5H8O4, is obtained. Compound B has IR absorptions at 2500-3000 (broad), 1730, and 1701 cm-1, and its proton NMR spectrum in D2O consists of resonances at ? 2.7 (complex splitting) and ? 3.7 (a singlet) in the intensity ratio 4:3. Give the structures A and B, omitting stereochemistry.
Can SO2 be maintained a liquid under a pressure of 100atm at 0 C. Can liquid methane be obtained under the same conditions.
One liter of a buffer solution is prepared by dissolving 0.115 mol of NaNO2 and 0.070 mol of HCl in water. What is the pH of this solution? If the solution is diluted two fold with water, what is the pH?
2300 grams of water is heated. If this water starts at a temperature of 17 degrees Celsius, what amount of heat is needed to boil away all of this water?
The confirmation test for Ag^+ is to add HNO3 to the [Ag(NH3)2] ^+ and see if a precipitate of AgCl forms. Where does the Cl ^ - come from. Why does adding HNO3 make AgCl precipitate
What mass of H2O is required to form 1.3L of O2 at a temperature of 320K and a pressure of 0.957atm.
Calculate the volume of carbon dioxide gas at stp, produced when 651g of ammonia carbonate (NH4)2CO3 decomposes to produce ammonia gas (NH3) carbon dioxide and water vapor. Calculate the total volume of all gases produced under those conditions.
