1.	The constituents of this material that is yttrium, barium and copper are in ____________(a) 1:1:1(b) 1:2:2(c) 1:2:3(d) 1:2:1This question was posed to me at a job interview.The origin of the question is Super Conductors in section Nano Materials of Applied Chemistry
Answer» Correct choice is (C) 1:2:3 To EXPLAIN I would say: The CONSTITUENTS of this material that yttrium, barium and copper are in 1:2:3 MOLAR stoichiometric ratios and hence are called as 1:2:3 SUPER conductors.
