Text Solution

Verified by Experts

The correct Answer is:
A, B
Dihydrogen can be prepared on commerical scale by different methods. Reaction of steam. On hydrocarbons or coke at high temperature in the presence of catalyst yield hydrogen
`C_(n) H_(2n+2) + nH_(2)O+ 2 overset(1270K)to nCO_(2) + (2n + 1)H_(2)`
` e.g.," "CH_(4)(g) + H_(2)O(g) underset(Ni)overset(1270K)to CO(g) + 3H_(2)(g)`
The mixture of CO and `H_(2)` is called water gas. As this mixture of CO and `H_(2)` is used for the synthesis of method and a methanol and a number of hydrocarbons, it is also called synthesis gas or 'syn gas'.
