Potassium permanaganate and chromic acid can both be used as classification tests for alcohols. methanol and two amino acids are the hydrolysis products of aspartame. Why is potassium permanganate a better choice as a classification test reagent than chromic acid to detect the methanol produced by aspartame hydrolysis? Select all that apply. Chromic acid doesn't display a color change when it oxidizes alcohols and so cannot be followed visually. Chromic acid is too weak of an oxidizing agent to oxidize alcohols. Potassium permanganate oxidizes amino acids slower than it oxidizes alcohols. Potassium permanganate loses its purple color as it oxidizes alcohols, so the reaction can be followed visually. Chromic acid also oxidizes amino acids, and will give a false positive color change.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
