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.

As Chemistry Moderators (Tinuviel and UltimaOnline), instead of
a) spoon feeding you the answers,
b) hogging/beating everyone else to the answers and not giving other students a chance to discuss,
We'll therefore leave it to other students to give the answers and/or comments, and we'll only give comments and/or check the posted answers when asked to do so.
Also, for everyone who posts questions here, you should at least post what you think might be the answer, or what you understand about the question, instead of just the question itself.
This would be more helpful in your learning process. (if you just wanted model answers, you can lookup the TYS Answer Booklet; the advantage of a forum is for interactive learning).
HOWEVER, seeing how miss maple is a newcomer to the forum, we'll be more welcoming ("Welcome to the HomeWork Forum! PS. If you're looking for Chemistry, Physics, Mathematics Tuition, you can contact UltimaOnline, Eagle and Tinuviel!"), so here's a one-time discount - I'll give the full answers directly.

Solutions :
Nitrogen molecule.
Barium metal is oxidized to Ba2+ cation. Protons (H+) from water is reduced to hydrogen gas, leaving OH- ions. Hence, products are Ba(OH)2(aq) and H2(g).
Carbon dioxide dissolves to form carbonic acid (CO2 + H2O --> H2CO3 --> 2H+ + CO3 2-), of which the carbonate anion (CO3 2-) bonds ionically with the Ba2+ cation to form the insoluble salt BaCO3(s) which precipitates out as a white solid.

1) u mean an eg of a diatomic molecule with a triple bond ?
hint: it is a gas that makes up ard 70 percent of air , u have heard of it in primary sch
Hints not the full solution
i) oxides of reactive metals further react with water to give hydroxide.
ii) CO2 is an acidic oxide , it will react with hydroxide to form salt and water
