Answer:
1. The pop sound comes from the small explosion formed by the burning of Hydrogen with oxygen.
2. Hydrogen gas is highly flammable . We can safely test for small quantities of hydrogen gas, collected in a test tube by holding a burning splint near to the top of the test tube. The positive result is a squeaky pop sound as the hydrogen reacts with oxygen in the air in a small explosion.
3. Sorry, don't know
4. 2H + O -> H2O + energy
