Equation :
2Zn + 2NaOH —> Na2ZnO2 + H2
The evolved gas is hydrogen. The test to confirm it’s presence: when we bring a burning splinter or a matchstick and it is put off with a ‘pop’ sound, then we can say that the gas evolved is HYDROGEN
The gas that’s will be evolved when zinc reacts with an acid is also hydrogen
For example: H2SO4 + Zn —>ZnSO4 + H2. [dont need to write this for the answer - I typed for u to understand the stuff]
Hope it helps ya
