What else can I help you with?
If you collected the gas produced by the photosynthesizing leaves how would you check if it contained oxygen?
The test for oxygen is to insert a glowing splint into a test tube and see if it glows brighter or re-ignites.
How can you test to see if there is oxygen in a test tube?
Light a splint on fire, and then blow the flame out. You want your splint to be glowing red. Then, simply put the splint into the mouth of the the test tube, and if your splint re-lights up into a flame, you'll know it's oxygen gas.
How could you test the gas released in reaction 6 to confirm its indentity?
To confirm the identity of the gas released in reaction 6, you could perform tests such as the pop test (putting a lit splint near the gas to see if it ignites with a pop), the limewater test (passing the gas through limewater to see if it turns milky, indicating the presence of carbon dioxide), or using a gas sensor to analyze the chemical composition of the gas.
What is it necessary to have a hot nicrome wire in the gas jar?
A hot nichrome wire in a gas jar is necessary for conducting the auto-ignition test of a gas. It is used to ignite the gas in the jar to see if it will burn by itself. If the gas ignites, it indicates that the gas is flammable.
Why when adding catalase and hydrogen peroxide into a tube makes it bubble?
Hydrogen peroxide (H2O2) reacts naturally in air to form oxygen and water. 2H2O2 > 2H2O + O2 Catalase is an enzyme found in most organisms which catalyses this process, so the bubbles you see are oxygen.
If you collected the gas produced by the photosynthesizing leaves how would you check if it contained oxygen?
The test for oxygen is to insert a glowing splint into a test tube and see if it glows brighter or re-ignites.
How would you test for gas when KMnO4 is heated?
When KMnO4 is heated, it decomposes to MnO2, releasing oxygen gas. To test for the presence of gas, you can do the following: Place a glowing splint near the reaction vessel to see if the gas relights the splint, indicating the presence of oxygen. Alternatively, you can bubble the gas through lime water (Ca(OH)2) to see if it turns milky, confirming the presence of carbon dioxide.
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.
What is oxygen the gas?
Oxygen is an element. See related link for more information.
How can you prove plant release oxygen?
The easiest way is to use an aquatic plant (one that grows underwater). In sunlight this will release bubbles - collect the bubbles in an upturned (water filled) jar placed over the plant. Once you have collected the gas use the oxygen test (relight a smoldering taper) on the gas to see if it is oxygen.
How can you test to see if there is oxygen in a test tube?
Light a splint on fire, and then blow the flame out. You want your splint to be glowing red. Then, simply put the splint into the mouth of the the test tube, and if your splint re-lights up into a flame, you'll know it's oxygen gas.
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 do pressure test on gas line?
To test a pressurerized gas line apply soapy water to all connections. You will see bubbles appear if there are leaks. I see plumbers do this at the houses I work on.
How would you test to see if a gas is hydrogen?
it will burn with a pop noise
What happens to the level of water in a test-tube as hydrogen is produced?
Ya... In a test tube add some aluminum foils and some amount of NaOH... Introduce the flame near mouth of the test tube... Then see the magic...
Does oxygen have texture?
texture is a relationship from what you can touch and see. If you can feel or see it; it has texture.
Can you see oxyen?
No. It is a colorless gas. The only way you can visually detect oxygen is when it displaces something else that you can see.
