CBSE Class 10 Answered

Magnesium ribbon is difficult to ignite to begin with. I have used a lighter and almost burnt my hand because I had it lit for so long. Then I used one of those torch lighters and it was a bit easier. The oxide coating on the ribbon will make it difficult to light but not that much more difficult. It is true that If you clean it with a bit of sandpaper before lighting, it will facilitate the contact of the ribbon with the flame.

We cannot entertain multiple question of this type, please post each question individually .
