Electrons fill the electron orbitals (s, p, d, or f) starting from the lowest energy level going to the highest energy level.
I hope this helps. let me know if you need more information such as what the
Answer:
The percent composition for nitrogen in chromium(III) nitrate is 6%.
Answer:
Mendeleev left spaces in his periodic table because he predicted there were elements that weren't discovered yet that would fit in these spaces.
Explanation:
Chemical energy is kept inside the bonds that are connected to withatoms with other atoms and molecules with other molecules.
Because chemical energy is kept in likestorage. It is an shape of potential energy.
When a chemical reaction takes place, the stored chemical energy is let out.
PV = nRT
Where:
P = pressure in atm = 700/760 = 0.9211atm
V = volume = 8.29L
R = gas constant, 0.08206 atm-L/mol-K
T = temperature in Kelvin = 200 + 273 = 473
n = numbers of moles = Mass/molar mass
mass of the compound = 30.5
we can rewrite the equation above as
PV = (Mass)/(Molar mass) * RT
