Question

plz help me.... balanced equation of
aluminium+ sodium hydroxide+ water ---- sodium aluminate + hydrogen...

Answer 1

Sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminium which is an amphoteric metal. The reaction is highly exothermic once established and is accompanied by the rapid evolution of hydrogen gas. The reaction is sometimes written as: 2 Al + 2 NaOH + 2 H2O → 2 NaAlO2 + 3 H.

Answer 2

here is your answer
2Al + 2NaOH + 6H2O = 2NaAl(OH)4 + 3H2
