Question

A compound, like water, can be broken down (decomposed) by:

filtration


electrolysis


distillation


evaporation

Answer 1

electrolysis is the correct answer.

Step-by-step explanation:

Water is decomposed into hydrogen and oxygen gases using electricity. A Hoffman electrolysis apparatus collects the two gases separately and shows the 2 to 1 ratio nicely. ... Hoffman electrolysis apparatus. 2 electrodes - one is nichrome wire and the other is platinum wire and foil.

Go look up Hoffman apparatus.

Answer 2

Electrolysis

Step-by-step explanation:

• Electrolysis refers to the process of decomposing an electrolyte by passing an electric current through it.
• Electrolytes are ionic compounds either in molten or aqueous form that may be decomposed by passing an electric current through them.
• Water is an example of an electrolyte that can be decomposed using electrolysis.
• During electrolysis cations undergo reduction at the cathode while anions undergo oxidation at the anode.

In this case;

At the Cathode;

4H⁺(aq) + 4e → 2H₂(g)

At the Anode;

4OH⁻(aq) → H₂O(l) + O₂(g) + 4e
