Expert Answer:

In the compound XCl2, metal X has the valency 2.
Valency of the sulphate is 2 and that of hydroxide is 1.
So the metal sulphate will have the formula XSO4 and the metal hydroxide will have the formula X(OH)2.
Balanced equation for the combustion of X in oxygen can be represented as:
2X + O2 → 2XO
