Chemistry: Molarity and Concentrations Determine the concentrations of Na₂CO₃, Na⁺, and CO₃²⁻ in a solution prepared by dissolving 1.31 × 10⁻⁴ g Na₂CO₃ in 2.00 L of water. Express all three concentrations in molarity.

You'll need to determine:

1. [Na₂CO₃]
2. [Na⁺]
3. [CO₃²⁻]

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

  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-

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
