A colourless gas G1, produced on treating conc. H2SO4 with common salt is introduced into one end of a glass tube. Through the other end, another pungent smelling colourless gas, G2 of molecular mass 17 is introduced. A white sublimate, S is produced inside the tube. Which of the following statements is wrong?
(a)
Both the gases G1 and G2 are water soluble
(b)
Sublimate S1 contains covalent bond and ionic bond
(c)
Sublimate, S when treated with caustic soda liberates G2 gas
(d)
Aqueous solution of each G1 and G2 gas is acidic in nature

Next Question :
The two surfaces of a biconvex lens has same radii of curvatures. This lens is made of glass of refractive index 1.5 and has a focal length 10 cm in air. The lens is cut into two equal halves along a plane perpendicular to its principle axis to yield two plano-convex lenses. The two pieces are glued such that the convex surfaces touch each other. If this combination lens is immersed in water (refractive index = 4/3), its focal length (in cm) is
