Consider four different samples: aqueous kbr, molten kbr, aqueous kf, and molten kf. current run through each sample produces one of the following products at the anode: liquid bromine, fluorine gas, or oxygen gas. match each sample to its anodic product.

The reaction q+r2=r2q is found to be first order in r2 and

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
