Question

Why is magnesium ribbon burnt in air?​

Answer 1

Answer:

It is due to combustion.

Explanation:

When Magnesium ribbon is exposed to air (Oxygen), it starts reacting with it to form Magnesium Oxide (the leftover burnt ash). However, only exposure to air is not enough, the air it is being exposed must have sufficient amount of Oxygen in it and it must be heated at least above it's ignition temperature to start the Combustion.

The word equation for the reaction is:

Magnesium + Oxygen = Magnesium Oxide.

(Mg) + (O_2) = (MgO)

Balanced Equation:

(2Mg) + (O_2) = (2MgO)
