Write word equation for the chemical reaction that occurs when solid sodium oxide is added to water at room temperature and forms sodium hydroxide (dissolved in the water).

Explanation:

When solid sodium oxide reacts with water in a room temperature, it forms sodium hydroxide.

The one word equation of the reaction will show or represent the reactants on the left hand side of the arrow and the products on the reaction on the right hand side of the reactants.

Thus the equation of the reaction is :

Sodium oxide + water ---- sodium hydroxide.

  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-
