A compound A(C6H6) undergoes catalytic hydrogenation over lindlar catalyst to give a compound B, which in turn undergoes ozonolysis followed by workup with aqueous H2O2 to yield succinic acid and two equivalents of formic acid. in the absence of a catalyst poison, hydrogenation of A gives hexane. Propose a structure for compound A
According to quantum mechanics, the energy levels for an particle with mass m (such as an electron) confined in a 1-dimensional box of length a is given by
For H3PO4, a tripotic acid, Ka1 = 7.1 × 10-3, Ka2 = 6.3 × 10-8, and Ka3 = 4.5 × 10-13. What is the pH of a solution which contains 0.200 mol of K2HPO4 and 0.300 mol of Na3PO4 per liter of solution?
An analysis showed that 25.0 g of this hydrate, CoCl 2 * 6 H 2 O, contains 11.3 g of water. What is the percent water by weight in this hydrate?
determine partial pressure and number of moles of each gas in a 17.25 L vessel at 30 degrees celsius containing a mixture of xenon and neon gases only.
Calculate the entropy change when 100 g of argon is heated and compressed from 300 K, 1.0 atm, to 900 K, 17 atm
How many mL of a 2.0 M solution of NaOH would bve needed in order to have 0.500 mol of NaOH? (Molar mass of NaOH is 40.0 g/mol)
Write a net Ionic equation for the reaction that takes place when aq barium chloride soln reacts with an aq soln of potassium phosphate.
First, plot the potential energy as a function of the electron's distance from the nucleus, i.e.,V(r) . (Be sure to remember the sign of this potential.)
In oxidation of benzoin to benzil with nitric acid, why it is important to avoid heating the mixture above 70 °C? What is the possible side product if this happens
Three compounds are to be separated using HPLC. Compound A and Compound B have the same polarity but are more polar that Compound C. Compound A and Compound C have the same molecular weight (5000), and Compound B has a molecular weight of 26,000.
the chemical reaction between reagents supplied from an outside source. What is the emf of a cell fuelled by (a) hydrogen and oxygen, (b) the combustion of butane at 1.0 bar and 298 k.
Write a net ionic equation to explain why the pH didn't go up to about 10, as it would have if that amount of NaOH were added to distilled water or to 20ml 0.00040 M HCL, which also would have a pH of 3.40
