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 ;)
