A white solid dissolves in water to form a neutral solution. No precipitate forms when this olution is treated with a solution of NH4CL/NH3 buffer, nor when (NH4)2S is added. When the solution is acidified with HC2H3O2 and K2CrO4 is added, a yellow precipitate forms. This precipitate dissolves upon addition of concentrated HCL. Acidification of a solution of the solid with HNO3 followed by addition of AgNO3 causes formation of a white precipitate. What is the identity of the original solid?

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
