Identify the Lewis acid in this balanced equation:

Ag+

NH3

Ag(NH3)2+

Hello, how are you? At point one of the image, the reactions that are formed are:

in the case of reaction A it is the formation of a binary salt.

And in the case of reaction B it is a combustion reaction and this is because oxygen is present in the reactants, and as a product of carbon dioxide and water, the combustion of the organic compound that you see on the right is what would give the combustion reaction.

Regarding point two, the reaction we see would give as a product to hydrochloric acid (acid) with barium sulfate (quaternary salt). The comp equation

leta of exercise number two would be:

BaCl2 + H2SO4 => BaSO4 + HCl

And as for exercise number three, the isomers are compounds A and B, since we count the amount of carbons and hydrogens, both have 6 carbons and 14 hydrogens, therefore their chemical formula is the same, what differs is the location spatial and how the unions between the carbons occur.

Explanation:

In this photo that you sent you have exercises in organic and inorganic chemistry, the first points refer to inorganic chemistry, while the last one deals with organic compounds, where we talk about compounds that consist of the essential molecular ones called "CHON", and which They are often used a lot in the chemical industry.

In some of the reactions we are talking about there are formations of quaternary and binary salts, the salts are classified into three groups, where the simplest are the binary ones, then the tertiary ones and finally the quaternary ones.

As for the combustion reaction, what I can add to this topic is that it is an IRREVERSIBLE reaction where exotherm occurs, and it is a COMPLETE COMBUSTION, this means that the fuel agent was completely consumed and "burned" by Complete, there are incomplete combustions but it is irrelevant and it is not what your teacher asked you in this exercise.

Finally I wanted to tell you that the formation of hydric acids are the union between a chemical element with Hydrogen, the most common example of these acids is the hydrochloric acid that is found in our stomach to be able to degrade or denature proteins, amino acids and other food structures.
