How many ions are in 4.26 moles of ammonium

Explanation:The formula for ammonium carbonate is (NH4)2CO3

The molar mass of ammonium carbonate is 96.1 g/mole

51 g x 1 mole/96.1 g = 0.531 moles (NH4)2CO3

There are TWO moles of NH4+ (ammonium ions) per 1 mole of ammonium carbonate, thus ...

Moles of ammonium ions = 0.531 moles (NH4)2CO3 x 2 moles NH4+/mole (NH4)2CO3 = 1.1 moles NH4+ ions (to 2 sig. figs.)

  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-
