Current Question (ID: 8655)

Question:

$\text{Correlate the items listed in Column I with those listed in Column II.}$ $\text{Column I} \qquad \text{Column II}$ $\text{A. Synthesis gas} \qquad 1.\text{ Na}_2[\text{Na}_4(\text{PO}_3)_6]$ $\text{B. Heavy water} \qquad 2.\text{ Mixture of CO and H}_2$ $\text{C. Calgon} \qquad 3.\text{ Prolonged electrolysis of water}$ $\text{D. Salt like hydrides} \qquad 4.\text{ Stoichiometric compounds of s-block elements}$

Options:

1. $\text{A-4, B-3, C-2, D-1}$
2. $\text{A-2, B-3, C-1, D-4}$
3. $\text{A-1, B-4, C-3, D-2}$
4. $\text{A-4, B-1, C-3, D-2}$

Solution:

$\text{Hint: Calgon is }\text{Na}_2[\text{Na}_4(\text{PO}_3)_6]$ $\text{A. Synthesis gas -Mixture of Co and H}_2$ $\text{B. Heavy water-Prolonged electrolysis of water}$ $\text{C. Calgon-Na}_2[\text{Na}_4(\text{PO}_3)_6]$ $\text{D. Salt like hydrides-Stoichiometric compounds of s-block elements.}$
