Determine whether the following reaction is a Lewis acid/base reaction and if so, what is the Lewis acid: Fe3+(aq) + 6 CN−(aq) →
Aleonysh [2.5K]

Answer: It is a Lewis acid/base reaction, and Fe^{3+} is the Lewis acid.

Explanation:

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Fe^{3+} can readily accept electrons and thus act as a lewis acid which is short of electrons.

CN^- can readily lose electrons and thus act as a lewis base which has excess of electrons.

It is a Lewis acid/base reaction, and Fe^{3+} is the Lewis acid.

Which statement explains why the noble gases are so unreactive? They have one valence electron. They have eight valence electron
SVETLANKA909090 [29]

Answer:

The answer to your question is: The second option.

Explanation:

Atoms are stable when they gain or lose electrons to have 8 electrons.

They have one valence electron.  Noble gases have 8 electrons, not one, If they would have 1 electron they would be extremely reactive.

They have eight valence electrons. This is the right answer, noble gases have 8 electrons that is why they are unreactive.

They have seven valence electrons.  If noble gases would have 7 electrons, they would be very reactive.

They have two valence electrons. This option is incorrect, elements that have 2 electrons are reactive like Calcium, Magnesium, etc.

If an atom contains more electrons than protons, it is a action, an anion, or electrically neutral
barxatty [35]
Electrons hold a negative charge, and anion refers to a negatively charged atom.

The answer is anion. Here's a way to help remember:

Cats have paws, and cations are "paws"itive (positive).
