I believe the correct answer from the choices listed above is option 1. Water is classified as a compound because it can <span>be broken down by chemical means. This process is called electrolysis where the products are H2 and O2. Hope this answers the question. Have a nice day.</span>
Compounds are the substances which contain two or more different elements.
Similarly, water is a compound as it is made up when two hydrogen atoms combine with one oxygen atom. Compounds can be broken down with the help of chemical reactions.
Hence, the statement water can be broken down by chemical means explains why water is classified as a compound.
