What is the difference between Sn1 and SN2 reactions in organic chemistry?
A rock is found to contain 83.7% of the amount of uranium-238 that it contained when it was formed. (The amount that the rock contained when it was formed can be deduced from the presence of the decay products of u-238 .) How old is the rock?
In the bromination of ethane (C2H6) reaction, one wants to produce 10.0 g of C2H5Br product. How many grams of C2H6 would be needed to react with excess Br2.
Question- Draw the substitution products for the following reaction, assuming that the reaction is carried out under SN2 conditions. If the products can exist as stereoisomers, show what stereoisomers are formed: (3S,4S)-3-bromo-4-methylhexane + C..
Question- Carbon disulfide is prepared by heating sulfur and charcoal. The chemical equation is S2(g) + C(s)= CS2(g). KC=9.40 at 900K.
If the liquid effluent from the press could be fed to the spray dryer without afffecting the tasteof the product, by what percentage would the production rate of instant coffee be increased
Some AgCl(s) has been placed in a beaker of water. After some time, the solubility of Ag+ and Cl- was measured to be 2.5 x 10-5 M. Determine whether the system has reached equilibrium.
The second-order decomposition of NO2 has a rate constant of 0.255 M-1s-1. Explain How much NO2 decomposes in 4.00 seconds if the preliminary concentration of NO2 (1.00 L volume) is 1.33 M
Pure acetic acid known as glacial acetic acid is a liquid with a density of 1.049g/mL at 25 degrees celicus. Calculate the molarity of a solution of acetic acid at 25 degrees celicus in enough water to make 250.0mL of solution.
The Ksp of CaSO4 is 4.93X10^-5. Calculate the solubility (in g/L) of CaSO4(s) in 0.500 M Na2SO4(aq) at 25 °C.
Why is it not possible for the molar mass of a monoprotic acid to have a value less than 1g/mol
If the gas was not pure butane but 10 mole percent propane and 90 mole percent butane then determine how would the MW value be affected?
An electric power station annually burns 3.6 107 kg of coal containing 1.8 percent sulfur by mass. Calculate the volume of SO2 emitted at STP.
