Question

(a) When magnesium ribbon is burnt in air, two products are formed. Point out the oxidising and reducing agents in this reaction.
(b) Define oxidiation in terms of removal of hydrogen. [1 ½ x 2 = 3]

Answer 1

Explanation:

a) When magnesium ribbon is burnt in air , it react with oxygen to give magnesium oxide . A fine white powder is formed in this reaction. This undergoes exothermic reaction.

b) Oxidation is usually used to describe a process in which electrons are removed from a molecule or atom. Here's an example: ... Oxidation means the addition of oxygen to a molecule or the removal of hydrogen from a molecule. Reduction means the addition of hydrogen to a molecule or the removal of oxygen from a molecule.
