People who have sent you friend requests are visible by clicking the friend request icon in the menu bar. Friend requests you have sent are visible in your Activity Log, using filter Friends: (you may have to click more to see it).
on facebook, people usually either accept or deny a friend request right away. well, i usually accept most of them when i first see it. guess they feel bad if they deny it but then they don't see you as a friend or don't want to get to know you so they don't accept the request either. The best thing to do (in their opinion) is to leave the request hanging so they don't have to deal with it.
