Burning of magnesium ribbon class 10, class10 board 2026 important question, #class10science #shorts class 10 science science class 10 boards class 10 science science chemistry class 10 #boards2026 #science #scienceclass10 🔥 Burning of Magnesium Ribbon – Explanation When a magnesium ribbon is burned in air, it reacts with oxygen to form magnesium oxide (MgO), producing a bright white flame and white ash. --- Chemical Reaction: 2Mg (s) + O_2 (g) → 2MgO (s) --- Observation: The magnesium ribbon burns with a dazzling white flame. After burning, it leaves behind a white powdery ash, which is magnesium oxide (MgO). --- Precautions: 1. Clean the ribbon with sandpaper before burning — this removes the oxide layer formed on its surface, which would otherwise slow down the reaction. 2. Do not look directly at the flame — it is very bright and can harm your eyes. 3. Use tongs to hold the ribbon while burning. --- Word Equation: Magnesium + Oxygen → Magnesium Oxide --- Uses: Demonstrates combustion and oxidation reactions. The white MgO formed is basic and used in medicine and refractory materials. thanks 🙏 please subscribe
