Westclox32897BF Round Butterfly Wall Clock, 12"

Is the ticking loud on this clock?

Can you please tell me where the catch is located on the back of this clock? does it hang from a catch in the center or at the top?

Does this clock use an alkaline battery? Many of the clocks on Amazon say no alkaline, only carbon zinc. Where do you even buy carbon zinc batteries?

does this clock have a glass face cover
