Question

Correlate the items listed in Column I with those listed in Column II. Find out as many correlations as you can.

Column I	Column II
(i) Synthesis gas	(a) $$\mathrm{Na}{\phantom{A}}_2[\mathrm{Na}{\phantom{A}}_4(\mathrm{PO}{\phantom{A}}_3){\phantom{A}}_6]$$
(ii) Dihydrogen	(b) Oxidising agent
(iii) Heavy water	(c) Softening of water
(iv) Calgon	(d) Reducing agent
(v) Hydrogen peroxide	(e) Stoichiometric compounds of s-block elements
(v) Salt like hydrides	(f) Prolonged electrolysis of water
	(g) $$\mathrm{Zn}+\mathrm{NaOH}$$
	(h) $$\mathrm{Zn}+\mathrm{dil}\cdot \mathrm{H}{\phantom{A}}_2\mathrm{SO}{\phantom{A}}_4$$
	(i) Synthesis of methanol
	(j) Mixture of $$\mathrm{CO}$$ and $$\mathrm{H}{\phantom{A}}_2$$
