Answer:
Total Energy of the electrons
Explanation:
An atom in an excited state is when the total energy of electrons can be lowered by transferring molecule(s) over to different orbitals. in an excited state atom, not all electrons are at the lowest energy levels
Answer:
207.89g
Explanation:
The formula of the compound is:
Fe₂S₃
Find the molar mass of the compound;
Atomic mass of Fe = 55.845g/mol
S = 32.065g/mol
Now;
Molar mass of Fe₂S₃ = 2 (55.845) + 3 (32.065)
= 207.89g
