Answer:
5 atoms
Explanation:
When a chemical reaction starts with 5 atoms of hydrogen, and the reaction goes into completion, it must give us 5 atoms of hydrogen.
This is in compliance with the law of conservation of mass which states that "in a chemical reaction, matter is neither created nor destroyed but converted from one form to another".
In chemical reactions, bonds are broken and new compounds are formed in the process. The same number of species at the start and end of the reaction must still be the same.
<u>Answer:</u> 
is an acid, 
is a base, 
is conjugate base and 
is conjugate acid
<u>Explanation:</u>
According to Bronsted and Lowry's theory:
An acid is defined as a proton donor while a base is defined as a proton acceptor.
In a chemical reaction, an acid loses a proton to form a conjugate base while a base accepts a proton to form conjugate acid.
For the given chemical reaction:
is losing a proton thus it is an acid to form which is its conjugate base
is gaining a proton thus it is a base to form which is its conjugate acid
Hence, is an acid, is a base, is conjugate base and is conjugate acid
