what forms a diatomic molecule with a triple bond ?

(i)write the equation for the reaction between barium and water.
my ans : chemical equation: barium + water → barium oxide + hydrogen ?

(ii) what would you expect to see if carbon dioxide is passed into the solution remaining from the reaction in  (i)[the abv qns]. Give a reason.

Mod edit - I've changed the subject of your post to be formatted as a question - please do this in future to help keep the forum tidy and easy to navigate.  Thanks!

Look at the periodic table - Ba is the same grp as Ca (Gp II) so it's chemical properties will be similar.
Drop some in water and you'll get the hydroxide, bubble CO2 through it and you'll precipitate the carbonate (all carbonates are insoluble except Na).

Many other carbonates are soluble:

K2CO3
Rb2CO3
Cs2CO3
(NH4)2CO3

Li2CO3 is soluble a little.
