NCERT Fig 1.1 · interactive diagram

Parts and their functions

• Magnesium ribbon (मैग्नीशियम रिबन) — Clean it with sandpaper first to remove the oxide layer, otherwise it will not burn easily.
• Tongs (चिमटा) — Hold the burning ribbon with tongs, as far as possible from your eyes.
• Dazzling white flame (चकाचौंध करने वाली श्वेत लौ) — Mg burns with a dazzling white flame — energy is released as heat and light.
• Watch-glass (वाच-ग्लास) — Collect the ash in a watch-glass held below the burning ribbon.
• Magnesium oxide (white powder) (मैग्नीशियम ऑक्साइड (सफ़ेद पाउडर)) — Product: 2Mg + O₂ → 2MgO. A new substance with new properties = a chemical change.
