Using the table of thermodynamic data, calculate (delta) H for the following reaction, assuming it is independent of temperature.
H2O(g) + C(s) <__----> CO(g) + H2 (g)
The major product of the reaction is 2-ethoxy-2,3-dimethylbutane. In addition, 2,3-dimethyl-2-butene, 2,3-dimethyl-1-butene, and 3,3-dimethyl-1-butene are produced as minor products. Suggest a mechanism
aliquots were transferred to 50-mL volumetric flasks. Each was treated with standard (containing ), diluted to volume with , and analyzed by flame atomic absorption.
Ice has the unusual property of a melting point that is lowered by increasing pressure. if this is the reason we can skate on ice, would a 75-kg skater whose skates contact the ice with an area of 0.1cm^2 be able to skate at -3C
explain why this series of reaction will produce the 3,5-dibromotoluene and direct bromination of toluene produces the 2,4-dibromotoluene.
a 19.3 g mixture containing sodium sulfide and calcium chloride. 86.9% sodium sulfide and 63.9% by mass chlorine. what is the grams of chlorine?
what is the mechanism of the dehydration of 2-butanol. Why is sulfuric acid rather than HCl used to catalyze the reaction.
could 131g of xenon gas in a vessel of volume 1.0dm^3 exerts a pressure of 20 atm at 25C if it behaves as a gas? if not what pressure would it exert? (b) what pressures would it exert if it behaved as a van der waals gas?
A typical automobile gets 30 miles per gallon of gas and drives 12,000 miles every year. Assuming that octane (C8H18, density 0.7025 g cm-3) is a principal component of gasoline
A 493 mL sample of solution contains 33.2 g of CaCl2 Calculate the molar concentration of Cl in this solution
Let's say that you are given a 0.215g of unknown weak acid and asked to dilute with 75 mL of DI water. You then use a standardized 0.125 M NaOH to titrate the unknown acid solution
Describe in detail the manufacture of silicon crystals. Describe the process
This buffer is to be prepared by mixing 25.0 mL of 0.1 M HCl with the correct mass of solid sodium acetate. You will determine the mass of solid sodium acetate needed.
