Why is it necessary to remove CO when ammonia is obtained by Haber’s process ?

In Haber’s process, hydrogen is obtained by reacting methane with steam in presence of NiO as catalyst. The process is known as steam reforming. Why is it necessary to remove CO when ammonia is obtained by Haber’s process?

Why is it necessary to remove sulphur from petroleum products?

Mention the conditions required to maximise the yield of ammonia in its synthesis by Haber’s process.

What is the coordination entity formed when excess of aqueous KCN is added to an aqueous solution of copper sulphate? Why is it that no precipitate of copper sulphide is obtained when H_2S(g) is passed through this solution?

A small bar magnet has a magnetic moment 5Am^2. The neutral point is obtained on axial line when it is placed in magnetic meridian with its N pole pointing S of earth and neutral point is obtained on equatorial line, when it is placed with its N pole pointing towards north of earth. If horizontal component of earth's field is 0.38G, find the position of neutral points in the two cases.
