Can you take a better pic cant see the questions
Answer:
Reductio is gain of electrons, while oxdation is loss. The oxidtion states of carbon in the reaction will show either of oxidation or reduction occurrence.
→ 
Explanation:
Electrons displacement is explained for each reaction below:
- +2 to +4 = loss of 2 more lectrons-------oxidation
- +4 throughout reaction----no exchange of electrons
- -4 to +4 = loss of 4 electrons-----oxidation
- 0 to -2 = gain of 2 electrons-----reduction
I think it’s a maybe hope this helps
<span>Molten barium
chloride is separetes:</span><span>
BaCl</span>₂(l) →
Ba(l) + Cl₂(g), <span>
but first ionic bonds in this salt are separeted
because of heat:
BaCl</span>₂(l) →
Ba²⁺(l) + 2Cl⁻(l).
Reaction of reduction
at cathode(-): Ba²⁺(l) + 2e⁻ → Ba(l).
Reaction of oxidation
at anode(+): 2Cl⁻(l) → Cl₂(g) + 2e⁻.
The anode is positive
and the cathode is negative.
