Echeveria, yes they flower, I have one flowering now. and after they finish there's not much left of the plant.

It should be Echeveria.

Will that long thing over the edge of the bowl turn into a flower or that is the flower?

Its a flower and it will make seeds and then die.

Yes I concur, an Echeveria. Similar pale-leaved species include E. colorata, E. elegans, etc., but there are also many hybrid cultivars.
When it does flower, a more precise identification may be possible. Echeveria flowers are beautiful in their own right, and quite popular with hummingbirds.
Just to note, a well-grown Echeveria rosette is quite perennial and will not die after flowering. Some of the previous posts seem to suggest otherwise.
