Answer:

i)

  • X is magnesium (Mg)
  • Y is magnesium oxide(MgO)
  • Z is magnesium hydroxide Mg(OH)2____"2" will be in subscript

ii)

  • Mg + O² -----> MgO
  • MgO + H²O -------> Mg(OH)²

iii) it is an example of exothermic reaction as heat is released when Mg is burnt in oxygen.

note - the "²" in the reactions should be in subscript but I can't find how to write those in subscript so that's why I wrote it in superscript.

HOPE YOU FIND IT HELPFUL ;)
