Answer:
A fire extinguisher
Explanation:
A lab station usually contains equipment for the people working at the station to use. However, most rooms will only have one fire extinguisher for the whole room meaning it would most likely be located somewhere that is easy to access by all and not just a singular lab station.

You can tell that the atom is in the excited state because:
- Electron configuration should follow the 2-8-8-2 rule, meaning that the inner shell should be filled before the next shell can start holding electrons.
- Instead of the atom's electron configuration being in the ground state at 2-8-8-1, electrons from the second shell have jumped to the third.
Heterogenous mixtures are unevenly mixed. Like oil and vinegar in vinaigrette if it is not emulsified well enough and they separate. Any case where two things are not evenly distributed within each other.
Homogenous mixtures are evenly mixed throughout. Like salt water or kool-aid (when it's mixed).
