In which of the following reactions, \(\mathrm{MgO}\) is not formed?
- A \(\mathrm{Mg}+\mathrm{CO}_2 \longrightarrow\)
- B \(\mathrm{Mg}+\) dil. \(\mathrm{HNO}_3 \longrightarrow\)
- C \(\mathrm{Mg}+\mathrm{NO} \stackrel{\Delta}{\longrightarrow}\)
- D \(\mathrm{Mg}+\mathrm{B}_2 \mathrm{O}_3 \longrightarrow\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Mg}+\) dil. \(\mathrm{HNO}_3 \longrightarrow\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \mathrm{Mg}+2 \mathrm{HNO}_3 \rightarrow \mathrm{Mg}\left(\mathrm{NO}_3\right)_2+\mathrm{H}_2 \uparrow \\ & \text { dil. } \\ & \end{aligned}\) Hence, \(\mathrm{MgO}\) is not formed in this reaction.
