Metal X is Magnesium (Mg)
upon ignition, Magnesium burns to form a white powder which is Magnesium oxide
2Mg+O2→2MgO
Powder Y is Magnesium oxide
When water is added to Magnesium oxide, it forms Magnesium hydroxide Mg(OH)2 which is used as an antacid to relieve indigestion
Substance Z is Magnesium hydroxide.
MgO + H2O → Mg(OH)2
