Less reactive metals such as aluminum, zinc and iron react with steam to liberate dihydrogen gas.
True
Less reactive metals such as aluminum, zinc, and iron react with steam to liberate dihydrogen gas.
Metal+steam→Metal oxide+Hydrogen
Examples: When magnesium reacts with steam, it produces magnesium oxide and hydrogen gas
Mg(s) + 2H2O(g) ⟶ Mg(OH)2(s) + H2(g)
When Aluminum reacts with steam, it produces Aluminum oxide and hydrogen gas
2Al(s) + 3H2O(g) ⟶ Al2O3(s) + 3H2(g)
When Iron reacts with steam, it produces Iron Oxide and hydrogen gas
3Fe(s) + 4H2O(g) ⟶ Fe3O4(s) + 4H2(g)
