AP EAMCET · Chemistry · p Block Elements (Group 13 & 14)
An inorganic compound \((A)\) made of two most occurring elements in the Earth's crust and used in building construction, when made to react with carbon, forms a poisonous gas \((B)\) which is most stable diatomic molecule, compound \((A)\) and \((B)\) are
- A \(\mathrm{SiO}_2, \mathrm{CO}_2\)
- B \(\mathrm{SiO}_2, \mathrm{CO}\)
- C \(\mathrm{SiO}_2, \mathrm{~N}_2\)
- D \(\mathrm{CaO}, \mathrm{CO}_2\)
Answer & Solution
Correct Answer
(B) \(\mathrm{SiO}_2, \mathrm{CO}\)
Step-by-step Solution
Detailed explanation
Silicon ( \(\mathrm{Si}\) ) and oxygen \((\mathrm{O})\) both are present in Earth's crust and used in construction (in the form of \(\mathrm{SiO}_2\) ). \(\mathrm{SiO}_2(A)\) i.e. silicon dioxide is used in the building construction to produce concrete. In its crystalline form…
