What products results from this reaction?
please show arrow pushing, and I would upvote your
answer thank you
7.33 The agarose gel used for the electrophoresis of DNA is seaweed polysaccharide containing an unusual bicyclic subunit. An enzyme isolated from the red seaweed that produces the related polysaccharide porphyran has been shown to convert galactose 6-sulfate residues into the anhydrogalactosyl residues of agarose. Suggest a plausible!...
Hi. Can you please show me the step-by-step solution on
this one. (Please put labels on any formula so I can understand it
better). Thank you so much.
2Nal + Pb(NO3)2 + Pbl2 + 2NaNO3 32. If 4.61 grams of Pbl, was isolated from the reaction of Pb(NO3), and Nal, what will be the calculated amount of Nal that reacted...
