hydrogen: place a lighted splint into the container containing hydrogen, the result is a squeaky pop.
oxygen: place a glowing splint (a blowout splint) into the container containing oxygen, the result is the splint relighting.
carbon dioxide: bubble the gas through lime-water, the result is the lime-water turning milky/cloudy.
ammonia: place DAMP litmus paper over the container containing ammonia, the result is the litmus paper turning blue.

What is a test to show that gas is oxygen?
One way to test for the presence of oxygen gas is to use a glowing splint test. If the gas is oxygen, the glowing splint will relight when introduced into the gas due to oxygen's ability to support combustion.
How you would test for the gas and state what you would see in a positive test?
To test for a specific gas, you would typically use a method tailored to that gas. For example, to test for hydrogen, you would bring a lit splint close to the gas; a positive test would produce a characteristic 'pop' sound. For oxygen, you would use a glowing splint; a positive test would cause the splint to reignite. For carbon dioxide, you could bubble the gas through limewater; a positive test would turn the limewater cloudy.
How do you test for evolution of hydrogen gas?
You can test for the evolution of hydrogen gas by collecting a gas sample from the reaction using a gas syringe or inverted test tube. You can then test this gas by lighting a flame at the mouth of the container to see if it ignites with a 'squeaky pop' sound characteristic of hydrogen gas. Alternatively, you can use a glowing splint to see if it reignites in the presence of hydrogen gas.
How do you test oxygen gas during an experiment?
You can test for the presence of oxygen gas by using a glowing splint test. A glowing splint will reignite in the presence of oxygen. Alternatively, you can use a chemical reaction like the decomposition of hydrogen peroxide, which produces oxygen gas bubbles. Additionally, you can use an oxygen gas sensor to directly measure the presence of oxygen in the air.

How do you test for hydrogen gas?
One common method to test for the presence of hydrogen gas is the "pop test." Collect a sample of the gas in a container, then introduce a flame. If hydrogen is present, it will burn with a pop sound. Another method is to use a colorless, odorless gas detector that can detect hydrogen gas in the air.
How can I test a gas line for leaks?
To test a gas line for leaks, you can use a mixture of soap and water to check for bubbles along the line. Apply the solution to the connections and joints of the gas line and observe for any bubbles forming, which indicate a leak. Additionally, you can use a gas leak detector tool to detect any gas leaks in the line. It is important to ensure the gas line is turned off before conducting the test for safety reasons.
Teflon tape on natural gas piping?
Use the yellow tape. Its specifically for gas. I also use a small amount of pipe dope on the female fittings. Pressure test the new work separately, or if its a small add on use a soap solution to test your work.
How would you test a gas to prove it was oxygen?
One way to test if a gas is oxygen is by using a glowing splint test. A glowing splint placed in a test tube of the gas will reignite if the gas is oxygen. Another method is to use a colorimetric test strip specifically designed to detect oxygen, which will change color in the presence of oxygen gas.
How can I use the soapy water test to detect a gas leak?
To use the soapy water test to detect a gas leak, mix water with a small amount of dish soap to create a soapy solution. Apply this solution to the area suspected of a gas leak. If bubbles form, it indicates a gas leak as the gas is escaping and creating bubbles in the soapy water.
How do you check that it's a hydrogen gas?
To check if a gas is hydrogen, you can perform the "squeaky pop" test. Collect a small sample of the gas in a test tube and ignite it with a flame; if it produces a squeaky pop sound, it is likely hydrogen gas. Additionally, you can use a flame test in a controlled laboratory setting to see if the gas burns with a pale blue flame, characteristic of hydrogen.
Inferring what could you do to determine whether the gas produced as a result of these reactions is hydrogen?
You can use a simple test to determine if the gas produced is hydrogen. One way is to collect the gas in a test tube and test its flammability by carefully igniting it with a flame. Hydrogen gas will produce a pop sound when ignited. Another method is to perform a squeaky pop test by carefully introducing a flame directly into the gas using a wooden splint. If the gas is hydrogen, it will produce a distinctive squeaky pop sound.
