Question

10. Two non-metal atoms contain the same number of
electrons in their valence shells. One of the non-
metals in its most abundant form reacts with the
other non-metal forming a very stable compound
A. Compound A on reaction with oxygen and fused
sodium hydroxide gives two products B and C. B is
used as a raw material for the manufacture of glass
and C is the major constituent of glass. Identify A,
B and C. Write balanced chemical equations for
the above reactions,
2​

Answer 1

Answer:

(i) raw material used in the manufacture of glass and the major constituent of glass

(ii) identification of B and C

(iii) identification of A based on the composition of B and C

Answer 2

Answer:

The two non metals are having same number of valence electron. So they are of same group. Since one of the metal is most abundant it may be silicon. The two non metals are Silicon and carbon
