What accounts for the fact that liquid mercury forms into tight beads while ethyl alcohol do not?

Pretty sure this is wrong but worth a shot

Explanation:

Ethyl Alcohol is a clear, colorless liquid with a wine-like odor. It is used in alcoholic . Do not rely on odor alone to determine ... This chemical is on the Special Health Hazard Substance. Ethyl Alcohol can affect you when inhaled and by passing through the Ethyl Alcohol may form an ignitable vapor/air mixture in.

  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-
