The number of molecular orbitals formed is always equal to the number of atomic orbitals combined. 2. A molecular orbital can accommodate up to two electrons. 3. When electrons are added to orbitals of the same energy, the most stable arrangement is predicted by Hund's rule. 4. Low-energy molecular orbitals are filled before high-energy molecular orbitals are filled. A) 1 and 2 B) 1, 3, and 4 C) 3 and 4 D) 1, 2, and 3 E) 1, 2, 3, and 4Explanation / Answer
Ans 21. A. homogenous mixture of two or more substances
The solution is a mixture , because the components do not have a fixed ratio. It is basically composed of two components, solute and solvent. Solute is the substance in minor amount that dissolves into major component solvent to form a homogenous mixture.
