mathrm(Nh)_(3)+mathrm(MNO)_(2)

The reaction between ammonia (NH₃) and manganese dioxide (MNO₂) can vary depending on the specific conditions and the products desired. However, a common reaction involves the formation of manganese(II) oxide (MnO) and nitrogen gas (N₂). The balanced chemical equation for this reaction is:<br /><br />\[ 4 \mathrm{NH}_3 + 5 \mathrm{MNO}_2 \rightarrow 4 \mathrm{MnO} + 6 \mathrm{H}_2\mathrm{O} + \mathrm{N}_2 \]<br /><br />In this reaction:<br />- Ammonia (NH₃) reacts with manganese dioxide (MNO₂).<br />- The products are manganese(II) oxide (MnO), water (H₂O), and nitrogen gas (N₂).<br /><br />This reaction is an example of a redox reaction where manganese is reduced from an oxidation state of +4 in MNO₂ to +2 in MnO, and nitrogen is oxidized from -3 in NH₃ to 0 in N₂.
