Which represents the ionization of a strong electrolyte?
ô ch3ohi) ch3oh(aq)
k3po4(s) 3k+(aq) + po43-(aq)
h2co3(aq) + h+(aq) + hco3-(aq)
ch3cooh(aq) + h2o(l) 2 h30+(aq) + ch3c00-(aq)

c u c l 2 + 2 n a n o 3 → c u ( n o 3 ) 2 + 2 n a c l

  long weird answer but i hope this works

  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-

answer: mole of the gas

answer: mole of the gasexplanation:
