Explanation:
All are actual compounds. An example of an empirical formula could be CH2O, the empirical formula for carbohydrates like glucose (C6H12O6).
Atomic number shows the number of protons in an atom's nucleus. If the atomic number is 30, then it has 30 protons. The question says it is neutral, so it must have the same amount of protons and electrons.
A is the correct answer based on this.
1-boyle's law (pressure and volume)
2- Charles' law (volume and temperature)
3- Avogadro's law ( number of mole and volume)
4- Gay-Lussac's law ( pressure and temperature)
