Why does burning Mg continue to burn in ...

Why does burning Mg continue to burn in a jar containing NO but burning S gets extinguished ?

Text Solution

Verified by Experts

Magnesium is a strong reducing agent and reduces NO to form `Mg_(3)N_(2)`. The reaction is highly exothermic and NO decomposes to `N_(2) " and " O_(2)`.
`5Mg+2NOto 2MgO+underset("Mag. Nitride")(Mg_(3)N_(2)+heat`
`2NOoverset("heat")to N_(2)+O_(2)`
Oxygen keeps the magnesium ribbon burning. On the other hand, sulphur is a non-metal and acts as an oxidising agent and cannot reduce NO. Heat produced as a result of burning sulphur is not sufficient to decompose NO to `O_(2)`. Therefore, burning sulphur gets extinguished.
