(i) Synthesis of \[C{{H}_{3}}OH\] | |
(j) Mixture of CO and \[{{H}_{2}}\] |
Answer:
Synthesis gas is a mixture of CO
and \[{{H}_{2}}\]and used for manufacture of methanol
(i-i - j)
Dihydrogen is a reducing agent.
It forms stoichiometric compounds with s-block elements. It is prepared by
action of Zn and\[NaOH,Zn+Dil.{{H}_{2}}S{{O}_{4}},\]etc. It is used in the synthesis
of methanol.
(ii-d, e, g, h, i)
Heavy water is prepared by
prolonged electrolysis of water.
(iii ?f)
Calgon is \[N{{a}_{2}}[N{{a}_{4}}{{(P{{O}_{4}})}_{6}}]\]
and is used for softening of water
(iv-a, c)
Hydrogen peroxide acts as an
oxidising agent as well as a reducing agent.
(v-b, d)
Salt like hydrides are
stoichiometric compounds of s-block elements.
(vi-e)
