Final answer:

Copper, Aluminum sulfide, and physical mixture in Water + Sugar reaction.


Explanation:

Copper is the substance formed by combining Zinc + Copper as shown in the reaction: Zn (s) + CuCl2 (s) → ZnCl2 (s) + Cu (s).

No new substance is formed by combining Water + Sugar as it is a physical mixture rather than a chemical reaction.

Aluminum sulfide is the substance formed by combining Aluminum + Sulfur as in the reaction: 2Al(s) + 3S(s) → Al2S3(s).

Combining Iron + Chromium + Nickel does not form a specific substance as it involves a mixture of elements.
