Chemistry - Complete Pblock- Question with Solution | TestHub
Various s & p-block elements are often studied on the basis of their reactions, preparation of their oxy-acids, salts, bases and oxides. While major acids & salts can also be studied quantitatively, the qualitative nature of oxides is studied by observing their reaction with various oxides.
Which of the following reactin(s) are involved in preparation of CO.
Options:(select one or more)
Answer:
Solution:
A. The reaction of carbon with steam at high temperatures produces water gas, a mixture of CO and H₂:
B. In the blast furnace, coke reacts with air (O₂ and N₂) at high temperatures to produce producer gas, a mixture of CO and N₂:
C. Sodium oxalate decomposes in the presence of concentrated sulfuric acid to produce CO:
D. This reaction involves the decomposition of potassium ferrocyanide, which does not primarily produce CO.
Therefore, reactions A, B, and C are involved in the preparation of CO.
