Answer:
The answer to your question is:
Explanation:
a) P4⁰(s) + 10H⁺¹Cl⁺¹O⁻²(aq) + 6H2O(l) → 4H⁺¹3P⁺⁵O4⁻²(aq) + 10H⁺¹Cl⁻¹(aq)
It's a Redox reaction
Phosphorous oxidizes goes from 0 to +5
b) Br2⁰(l) + 2K(s)⁰ → 2K⁺¹Br⁻¹(s)
It's an oxidation reaction
Potassium oxidizes goes from 0 to +1
c) CH3CH2OH(l) + 3O2(g) → 3H2O(l) + 2 CO2(g)
It is not a REDOX reaction
d) Zn⁺²Cl2⁻¹(aq) + 2Na⁺¹O⁻²H⁺¹(aq) → Zn⁺²(O⁻²H⁺¹)2(s) + 2Na⁺¹Cl⁻¹(aq)
It's not a REDOX reaction
