The specific heat of a metal is found to be 0.03. 10 g of the metal gave on treatment with nitric acid, 18.9 g of pure dry nitrate.
Options:(select one or more)
Answer:
A, B, C
Solution:
By Dulong-Petit, A ≈ 6.4/0.03 ≈ 213, pointing to a heavy metal near 209 (Bi). From equivalents: 10/E = 18.9/(E + 62) 10(E + 62) = 18.9E E = 620/8.9 = 69.67. Valency = 209/69.67 = 3, so the metal is trivalent with A = 209 (bismuth), not an alkali metal. Hence (a), (b), (c).
