The quantum mechanical model is used to describe the energy and most likely location of an electron.
Answer: Option A
<u>Explanation:
</u>
The quantum mechanical model leads to the introduction of quantum numbers representing the energy levels, sub-shells, orbitals as well as spin states of the electrons. So according to the quantum numbers we can perfectly define the position and energy of any electron in an element.
According to Pauli’s principle, any two electron cannot be having same set of quantum numbers. So, using the principle quantum number, azimuthal quantum number, magnetic and spin quantum number, we can define the energy and location of an electron in the atom.
Answer:
The Equation for this reaction is as follow,
2 Cr(ClO₃)₃ → 2 CrCl₃ + 9 O₂
According to eq,
604.68 g (2mole) of Cr(ClO₃)₃ produces = 288 g (9 moles) of O₂
So,
146.5 g of Cr(ClO₃)₃ will produce = X g of O₂
Solving for X,
X = (146.5 g × 288 g) ÷ 604.68 g
X = 69.77 g of O₂
