NEET Chemistry Balancing Redox Reactions MCQ Question
Consider a diagram illustrating the redox reaction between magnesium and steam, where magnesium is oxidized. Which of the following correctly identifies the balanced chemical equation for this reaction?
Mg(s) + H2O(l) → MgO(s) + H2(g)
Mg(s) + 2H2O(l) → Mg(OH)2(s) + H2(g)
Mg(s) + H2O(l) → Mg(OH)2(s) + H2(g)
2Mg(s) + 2H2O(l) → 2MgO(s) + H2(g)
Correct Answer
Detailed Explanation
The balanced equation for the reaction between magnesium and steam is Mg(s) + 2H2O(l) → Mg(OH)2(s) + H2(g), as shown in the NCERT context.
