How many moles are in 0.456 g of chlorine

Mila [183]

Answer:

0.013 moles Cl

Explanation:

Grams --> Moles Divide by Molar Mass

Molar Mass of Chlorine (Cl) is 35.5. This can be found on the Periodic Table.

Set Up: (0.456 g Cl) (1 Cl / 35.5 g)

0.456 g * 1 = 0.456

0.456 / 35.5 = 0.01284507

Round to 0.013

What is the lowest unoccupied molecular orbital in F2?

Juliette [100K]

Answer:

σ*2pₓ, also called $3\sigma_{u}\text{*}$

Explanation:

I have drawn the MO diagram for fluorine below.

Each F atom contributes seven valence electrons, so we fill the MOs of fluorine with 14 electrons.

We have filled the $\pi \text{*2p}_{y}$ and $\pi \text{*2p}_{z}$ MOs.

They are the highest occupied molecular orbitals (HOMOs).

The next unfilled level (the LUMO) is the σ*2pₓ orbital. If you use the symmetry notation, it is called the $3\sigma_{u}\text{*}$ orbital.

This is the orbital that fluorine uses when it acts as an electron acceptor.

How to change aniline into phenyl isocyanide

olasank [31]

The reaction that best describes the change of aniline into phenyl isocyanide is
C6H5NH2 + CHCl3 + KOH → C6H5NC + 3KCl + 3H2O

This is basically a characteristic reaction of the primary amines. from the above reaction, we can see that aniline on carbyl amine reaction gives phenyl iso-cyanide.
