Sodium hydroxide with Al in H2O makes H2

2 Al(s) + 6 NaOH(aq) → 3 H₂(g) + 2 Na₃AlO₃(aq)

Hydrogen gas (dihydrogen)[9] is highly flammable and will burn in air at a very wide range of concentrations between 4% and 75% by volume.[10] The enthalpy of combustion for hydrogen is −286 kJ/mol:[11]

2 H2(g) + O2(g) → 2 H2O(l) + 572 kJ (286 kJ/mol)[note 1]
