Question - Why do dehydration reactions use acid as catalyst? Why can you not use base for dehydration reactions?
Any expert is able to provide answer for this problem in very short time
Problem- If an electron moves from n=5 to n=1, please answer the following: What is the energy associated with this electron movement? Is energy gained or lost? What is the wavelength associated with this electron movement
One way to do this is to mix oxygen with helium. Assume a mixture of 10.% oxygen and 90.% helium. Assuming Henry's law behavior, calculate the levels of oxygen and helium in the blood of a diver at 100 m. Assume T = 298 K.
Calculate a lattice energy for CaH2(s) in kilojoules per mole using the following information: (a) Eea for H(g) = -72.8kj/mol. (b) Ei1 for Ca(g) = +589.8kJ/mol.
Energy costs vary greatly with energy source: coal @ $25.00/ton, gasoline @ a pump price of $2.00/gal, and electricity @ $0.1000/kWhr. Conventional practice is to put these on a common basis by expressing
itself is insoluble in ice cold water. how would you precipitate acetyl salicyclic acid from an aqueous solution of sodium acetyl salicylate and what measures would you take to ensure complete precipitation
Why does transferring a F-C Acylation Reaction (ie/ toluene and acetyl chloride reaction) to HCl/ice quench the reaction?
Explain while a coil of red-hot platinum is exposed to the air, it cools quickly. While exposed to ammonia gas the coil continues to glow red-hot. Explicate this observation.
What mass of potassium bromide residue remains if 500.0 mL of 0.200 M potassium bromide solution are evaporated to dryness?
The protein insulin consists of two polypeptides termed the A and B chains. Insulins from different organisms have been isolated and sequenced. Human and duck insulins have the same amino acid sequence with the exceptions of six amino acid residue..
a researcher has a 500.0 ml solution that is 0.322 m in hg2no32 and 0.0104 m in pbno32. she plans to add solid
What is the equilibrium pH of the solution? Solve by graphical method (draw a log C -pH graph and label the pertinent info, show your charge balance for the equation)
an equilibrium mixture at 727ordm? contains 0.276 mol h2 0.276 mol co2 224 mol co and 0.224 mol h2o. co2 g h2 g ? co g
