Draw every stereoisomer for 1-bromo-2-chloro-1,2-difluorocyclopentane. Use wedge-and-dash bonds for the substituent groups, and be sure that they are drawn on the outside of the ring, adjacent to each other. The skeletal structure of one molecule is included to indicate the proper format; modify the X\'s on the given structure to create the first stereoisomer. c / \ c c l l c _ c V " " V X X X X
Synthesizing ethers via acid-catalyzed condensation reactions has limited usefulness. The conditions (sulfuric acid and heat) are also conducive to elimination products. Clarification of Organic Chemistry
calculate the external pressure that must be applied to seawater, 1.14 M total ion concentration at 10 degrees celcius if the maximum concentration allowed in the product water
Trace amounts of rare elements are found within groundwater and are of interest to geochemists. Europium and terbium are lanthanide-series elements that can be measured from the intensity of their fluorescence emitted when a solution is illuminate..
2.0 mL ethanol with 1.0 mL ethylene glycol (HOCH2CH2OH) calculate the theoretical vapor pressure at room temperature for the solution above. using raoults law
How much ethylene glycol (C2H6O2) the major component of antifreeze, must be added to 1 L of water to keep it from at -15 F? Kf= 1.86 C/m.
determine the initial concentration - Constant rate is 3.20×10-4 M/s for a zero-order reaction. concentration has dropped to 9.00×10-2 M after 60.0 seconds
Suppose we want a soln containing 150 micrograms of the protein at a concentration of .5 mg/ml. To do this we will first evaporate the liquid from enough of the protein soln to get 150 micrograms. How much coln do we need to start with? How much H..
The concentration of Mg2+ in seawater is 0.052 M. What is the pH when 95% of the magnesium ions will be precipitated as the hydroxide salt. (Ksp, Mg(OH)2 is 8.9 x 10-12).
draw a representation for TPCP that would represent its structure if the phenyls were perpendicular to the 5-membered ring (a paddle-wheel structure) and a representation that represents the propeller structure.
A student is given a soluble sodium salt containing one of eight possible anions (negative ions): acetate, chloride, bromide, iodide, sulfide, sulfate, or phosphate. the student adds some BaCl2 solution to the salt solution.
If glass beads in the lab were replaced by a material with less surface area, will liquid seperation be better or worse
Determine the molality of a solution of water dissolved in methanol for which the mole fraction of water is 0.46.
