Question

A shining metal M on burning gives a dazzling white flame and changes to a white powder N
(i) Identify M and N
(ii) represent the above reaction in the form of a balanced chemical equation
(iii) Does M undergo oxidation or reduction in this reaction. justify?

Answer 1

(i) M is Magnesium and N is Magnesium Oxide

(ii)2Mg + O2 gives 2MgO

Type:-Combination reaction

(iii)M undergoes Oxidation because Oxygen is being combined with compound of Magnesium And also its a gain of Oxygen

Answer 2

A shining metal M on burning gives a dazzling white flame and changes to a white powder N,in this situation the most probable answers of the given questions,are as follows -

i) According to the circumstances mentioned in the question, the metal which is denoted as the "M" is most probably the magnesium metal and the white powder which is denoted as the "N" is most probably the magnesium oxide.

ii) The above combustion reaction can be described by the following balanced chemical equation :

Mg + O = MgO

iii) Here,the "M" or the magnesium metal goes through an oxidation reaction and every combustion is an oxidation reaction,due to the addition of the oxygen.
