Answer 1

Sodium Hydroxide+Zinc = Sodium Zincate + Hydrogen

2NaOH + Zn = Na2ZnO2 + H2

Gas is Hydrogen

This can be detected by keeping a Burning Splinter near the mouth of test tube

Answer 2

Answer:

reaction : NaOH + Zn -----> Na2ZnO2 + H2

# the gas produced is hydrogen.

test of gas : when we take a burning splinter near it then it burns with a pop sound.

# when same metal will react with srong acid then hydrogen gas is produced.
