Using the lewis structure predict the geometrical structures of the following ions and state the hybridization of the central atom.
ion: N3-
ion: CO3^2-
ion: NO3-
ion: BF4-
Draw a structure for a compound that meets the following description: C4H8O with IR absorption at 3400 cm-1 and no absorption in the 1640-1680 cm-1 range
Calculate the molar solubility of Fe(OH)2 in a buffer solution where the pH has been fixed at the indicated values. Ksp = 7.9 x 10-16. (a) pH 7.0 M (b) pH 11.0 M (c) pH 13.6 M
The product of this reaction contains two stereocenters. Due to the stereospecificity of the bromination and the symmetry of the product, however, only the meso-diastereomer of stilbene dibromide is produced.
From the solubility data given, calculate the solubility products for the following compounds: a) SrF2, 7.3 x 10^-2 g/L b) Ag3PO4, 6.7 x 10^-3 g/L
