1. For each of the following reactions below, draw a voltaic cell . In your drawing include the anode, cathode, and show the flow of electrons. Balance the equation and calculate the E' cell. Write the cell notation. (a) Zn (s) + Ag+ (aq) → Ag (s) + Zn2+ (aq) ) (b) Rb (s) + Hg2+ (aq) Rb+ (aq) + Hg (s) (C) F2 (g) + H20 (1) ► 4F- (aq) + O2 (g) + H+ (aq)

Elements that do not have full outer electron shells will donate, share, or take electrons from other atoms. choose the items that have the correct binary ionic formula.

Which statement is true about hcl? (5 points) select one: a. it is a salt because it increases the concentration of metallic ions. b. it is a salt because it is formed by the reaction of an acid and a base. c. it is an acid because it increases the concentration of hydroxyl ions. d. it is an acid because it increases the concentration of hydronium ions.
