The work output of a machine can never be less than

The work output of a machine can be anything, depending on the friction
and other losses internal to the machine. But it can never be MORE than
the work input.

I suppose you might say that the work output can never be less than zero,
because there's no such thing as negative energy.

This is what i found on google “lithium and sulfide can react together to form litium sulfide(li2s). when lithium sulfide hydrolyses(breaks down) in air, it releases hydrogen sulfide which is characteristized by a rotten egg odor.” i hope this you for what your looking for
