186 grams of sodium oxide, a basic anhydride, are to be neutralized in a 2 step method. First the solid is added to excess water to produce an aqueous solution of sodium hydroxide. Second, phosphoric acid is added to the basic solution to completely neutralize the base, leaving an aqueous solution of sodium phosphate. How many milliliters of 6.00 Molarity phosphoric acid solution would be required to accomplish this neutralization?
Find the intrinsic conductivity for germanium. (Assuming ni = 2.5x 1019/m3 at room temperature.)
Why does a protic solvent favor E1 over E2? I know with Sn2 a protic solvent would surround the Nu: and hinder it from attacking, but in E2 there is not a nucleophilic attack.
The mass spectrum of a compound that contains two bromine atoms gives isotope peaks with relative intensities of 1:2:1 for the M, M+2 and M+4 peaks, respectively. Explain why.
At a potential of -1.00 V vs. SCE, carbon tetrachloride (CCl4) in methanol undergoes a reduc- tion to chloroform (CHCl3) at a mercury cathode:
What are the consequences of removing some of the phase transfer catalyst along with the hot reaction mixture after refluxing. a)The phase transfer catalyst acts to remove small amounts of water from the mixture leading to increased purity
