Hydrogen.
The chemical reaction is:HBr + NaOH = NaBr + H2O
Sodium Hydroxide does not undergoes chemical change with water. It just becomes dilute or aqueous.
Ammonia
When sodium and water react, they will produce aqueous sodium hydroxide and hydrogen gas. Here's the balanced equation for that reaction: 2Na + 2H2O --> 2NaOH + H2 This reaction is violently exothermic and should be done under very safe and controlled conditions. The hydrogen gas will likely ignite, which itself is a different reaction: 2H2 + O2 --> 2H2O
It's precipitation reaction.
You would observe precipitation of magnesium hydroxide.

Since aluminium oxide is an amphoteric oxide, it does react with the alkali sodium hydroxide in an aqueous medium. It is an acid base reaction.

When aqueous Ferric chloride is allow to react with Sodium hydroxide the reddish brown ppts. of ferric hydroxide are formed. FeCl3 (aq.) + 3NaOH = Fe(OH)3 + 3NaClThey form precipitates of Ferric hydroxide.
The reaction of zinc nitrate and excess sodium hydroxide begins with precipitation of zinc hydroxide ( Zn(OH)2 ), followed by dissolvement after adding excess sodium hydroxide ( 2 OH- ) to formation of zinc aat-ions ( [Zn(OH)4]2- )
