I noticed this spacing behind the stove, on the floor between wall and floor. Is this normal? Should I seal it with something?

As Steven mentioned, it's normal. That's a gap to prevent water on the floor or in your slab or foundation walls wicking up into the (moisture-sensitive) paper-faced drywall. There's only one reason you'd want to seal it up: if it's a path for air infiltration or exfiltration through the wall. If you discover that this is the case, you can seal it with a high-quality silicone caulk. Don't use drywall filler or spackle (they'll wick water) or spray foam (it's flammable and this is behind a stove).
