Balance the Reaction and Identify Which Species Is Reduced and Which

question 22

Multiple Choice

Balance the reaction and identify which species is reduced and which is oxidized. Na(s) + H₂O(l) → Na⁺(aq) + OH−(aq) + H₂(g)

• A) Na(s)+ H₂O(l)→ Na⁺(aq)+ OH−(aq)+ H₂(g);Na reduced,H₂O oxidized
• B) 2Na(s)+ 2H₂O(l)→ 2Na⁺(aq)+ 2OH−(aq)+ H₂(g);Na reduced,H₂O oxidized
• C) Na(s)+ H₂O(l)→ Na⁺(aq)+ OH−(aq)+ H₂(g);H₂O reduced,Na oxidized
• D) 2Na(s)+ 2H₂O(l)→ 2Na⁺(aq)+ 2OH−(aq)+ H₂(g);H₂O reduced,Na oxidized
• E) 2Na(s)+ 2H₂O(l)→ 2Na⁺(aq)+ 2OH−(aq)+ H₂(g);not a redox reaction
