Solution

Sure, here are the steps to test a gas to show that it is hydrogen:

  1. First, you need to collect the gas in a test tube. This is usually done by displacing water in a water-filled tube.

  2. After you have collected the gas, you need to perform the 'pop test'. This is the most common test for hydrogen gas.

  3. To do the pop test, you take a lit splint (a small wooden stick that is on fire at one end) and quickly insert it into the test tube containing the gas.

  4. If the gas is hydrogen, it will ignite with a 'pop' sound. This is because hydrogen is highly flammable and reacts with oxygen in the air to produce water, which causes the 'pop' sound.

  5. If there is no 'pop' sound, the gas is not hydrogen.

Remember to always follow safety procedures when handling flammable gases and fire.

Hydrogen gas burns in air. Exposing hydrogen to a flame causes it to react with oxygen, forming water. A small flame put into a test tube of hydrogen gas will burn it quickly with a loud popping sound. This is known as a 'pop' test. Propose how a pop test would be useful for detecting if a chemical change has occured.
