Answer:
Oxygen is oxidized and hydrogen is reduced.
Explanation:
Let's consider the redox reaction during the electrolysis of water in an electrolytic cell.
2 H₂O ⇒ 2 H₂ + O₂
The corresponding half-reactions are:
2 e⁻ + 2 H₂O ⇒ H₂ + 2 OH⁻
2 H₂O ⇒ O₂ + 4 H⁺ + 4 e⁻
Oxygen is oxidized since its oxidation number increases from -2 to 0.
Hydrogen is reduced since its oxidation number decreases from +1 to 0.
The only true answer is A.
products are on the right side of the reaction
products and reactants don't necessarily have same physical or chemical properties
It is the reactants that <span>are the atoms, molecules, or compounds that participate in the reaction.</span>
Every substance is either an element or a compound.
There is ionic compounds, molecular compounds, but they are all considered compounds.
Hope I helped.
