Using the Lewis concept of acids and bases, identify the Lewis acid and base in each of the following reactions: Fe(NO3)3(s)+6H2O(l)→Fe(H2O)63+(aq)+ 3NO3−(aq) NH3(g)+HCl(g)→NH4Cl(s) Drag the appropriate items to their respective bins.

Answer :

(1) is a Lewis-base and is a Lewis-acid.

(2) is a Lewis-base and is a 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.

(1) The given balanced chemical reaction is:

In this reaction, is an electron pair donor and is an electron pair acceptor.

Thus, is a Lewis-base and is a Lewis-acid.

(2) The given balanced chemical reaction is:

In this reaction, is an electron pair donor and is an electron pair acceptor.

Thus, is a Lewis-base and is a Lewis-acid.

the correct answer is boyle

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
