Question

an element M burns in oxygen to form an electrovalent compound MO. what compounds do u expect if this element is made to combine with chlorine and sulphur?

Answer 1

From the given reaction one can conclude that valency of M is +2
so with Chlorine it will form
Chlorine exhibits valency 1
Hence it will form MCl2

and With S it will form
Valency of S is 2
Hence it will form MS
