Sound waves need to travel through a medium such as a solid, liquid, or gas. The sound waves move through each of these mediums by vibrating the molecules in the matter. If you need more explained ust ask and I an give it more detailed :)
Answer:
None
Explanation:
Isomers are organic compounds that have the same molecular formula but different structural formula. What this mean is that these isomers have different arrangement of their atoms. Hence, they belong to different homologous series and exhibit different chemical properties. Hence, it is enough to access whether two different compounds are isomeric using their chemical formula as a yardstick.
Now let us look at our answers. We can see that none of the pairs have the same molecular formula
Weak acids ionise partially and their ionisation is reversible and the ions may react to give back the acid molecule (sorry i'm not sure if i am answering your question though)
