Farmers who raise cotton once used arsenic acid, H3AsO4, as a defoliant at harvest time. Arsenic acid is a polyprotic acid with

Bess [88]

Answer:

pH = 1.95

Explanation:

For polyprotic acids, it is generally assumed that all H⁺ comes from the 1st ionization step. The amount of H⁺ delivered into solution for the 2nd and 3rd ionization steps are in the order of 10⁻⁴M and 10⁻⁶M respectively and provide very little change in pH from the quantity delivered in the 1st ionization step.

Therefore... the [H⁺] concentraion and pH are computed as follows...

[H⁺] = √Ka₁[H₃AsO₄] = √(2.5 x 10⁻⁴)(0.500) M = 0.1118M

pH = -log[H⁺] = -log(0.01118) = 1.95

The highest energy occupied molecular orbital in the C-C bond of the C2 molecule is?

Butoxors [25]

The highest energy occupied molecular orbital in the C-C bond of the C₂ molecule is 2pπ orbitals.

<h3>What is Molecular Orbital Theory?</h3>

According to this theory,

Molecular orbitals are formed by intermixing of atomic orbitals of two or more atoms having comparable energies
The number of molecular orbitals formed is equal to the number of atomic orbitals combined.
The shape of molecular orbitals formed depends on the type of atomic orbitals combined
Only atomic orbitals having comparable energies and the same orientation can intermix
Bonding M.O. is formed by the additive effect of atomic orbitals and thus, has lower energy and high stability.
Antibonding M.O. is formed by the subtractive effect of atomic orbitals and thus, has higher energy and low stability.
Bonding M.O. is represented by $\sigma, \pi, \delta$ while Antibonding M.O. is represented by $\sigma^*, \pi^*, \delta^*\\$
