Answer:
pH=2.34
Explanation:
HBr -> H + Br
The dissociation it's complete, for that reason the concentration of the products is the same of HBr
[H+]=[Br-]=0.00234 M
pH= - log (0.00234)=2.34

<h3>What is a ketone?</h3>
A ketone can be defined as a class of organic compound that typically comprises a carbonyl group in which an atom of carbon (C) is covalently bonded to an atom of oxygen (O).
In this context, we can infer and logically deduce that a structure diagram which completes the table of physical structures of the main functional groups is as follows:

Explanation:
Certain actions and/or their method can affect the environment, such as leaving the sink on while brushing your teeth or not turning off a light when you leave the room. I personally make decisions to prevent my association with Greenhouse gases by turning off lights when I leave a room, using minimal water, recycling, etc.
