If oxygen gas is collected over water at temperature of 10C and pressure of 1.02 ATM and the volume of gas plus water vapor collected is 293 mL then what volume of oxygen at STP was collected?
fly
Burning splint test for hydrogen gas?
hydrogen gas is H2 When H2 reacts with oxygen and fire (energy) It is combustion H2+ 02= 2(H20) Which is water. In that state it is water vapor. A popping noise is also made. That is water vapor racing out. The burning splint tests, basically, is when an individual lights a splint. On lighting this splint, it should be placed near a bottle containing hydrogen gas [ H2 ]. On carrying out this action, the glowing splint may increase in size, regarding the size of the flame, that is. The Hydrogen gas, on the other hand, will make a popping sound. The intensity of the 'pop' will depend on the amount of Hydrogen gas collected in the bottle. Take care to ensure that no Hydrogen gas escapes, or is released from the bottle, until the splint is placed, at least 2 inches away from the opening of the bottle.
What gas is produced when metals react with an acid?
Hydrogen
What gas makes a popping noise when you light it?
The gas making the popping noise is hydrogen.
How can carbon dioxide be collected?
It everywhere in the air. In fact is takes up about 50% of the earth's atmosphere. Everytime you exhale, you are releasing carbon dioxide into the air while plants take this in for photosynthesis.
Why is ammonia collected by upward delivery and not over water?
Ammonia is collected by upward delivery because it is lighter than air and will rise through the apparatus. Collecting it over water can be problematic as ammonia can dissolve in water, forming ammonium hydroxide, thus contaminating the collected gas.
How is ammonia gas collected in the laboratory preparation of ammonia gas?
Ammonia gas is collected by upward displacement of air in the laboratory preparation. This involves passing the gas over water and collecting it by downward displacement because ammonia is lighter than air. The gas is then bubbled through water to dissolve any remaining gas before use.
Is argon an upward delivery gas?
No. Argon is slightly denser than air so would not be collected by upward delivery. In practice downward delivery would be unreliable as the difference in density is so small. However there is no way to prepare argon in the lab so the question is redundant.
Why the hydrogen gas collected from the reaction of the metal with acid is referred to as wet hydrogen gas?
It is called wet hydrogen gas because it is collected over water.
Why the hydrogen gas collected from the reaction of the metal with acid is called wet hydrogen gas?
Wet hydrogen is collected over a water surface.
How would you capture hydrogen from a chemical reaction of an acid and a metal?
The hydrogen in such a reaction can effectively be collected using an apparatus called the gas jar. THis can be done by fitting the reaction flask with cork and a delivery tube running from the reaction flask to the gas jar. As the reaction proceed, the hydrogen evolved will be collected in the gas jar.
How is dry hydrogen collected?
Dry hydrogen can be collected by passing the gas through a desiccant, such as calcium chloride or silica gel, to remove any moisture. Once the moisture is removed, the dry hydrogen gas can be collected in a gas collection apparatus such as a gas syringe or a gas bag.
Why is carbon dioxide collected by downwards delivery?
Carbon dioxide (CO2) is collected by downwards delivery because it is heavier than air. Almost all of our atmosphere is nitrogen (molecular mass = 28) and oxygen (molecular mass = 32), but CO2 has a molecular mass of 40.
What is the difference between upward and downward delivery?
If you r talking about gases Downward delivery:-collecting gases which are denser than air. e.g. carbon dioxide, chlorine. upward delivery :-collecting gases which are less dense than air. e.g. hydrogen.
Can you collect hydrogen gas over water?
Yes, hydrogen gas can be collected over water by displacing the water in a container with the gas. Hydrogen is less dense than air so it will displace the water, allowing the gas to be collected in the container while the water is pushed out.
What happened when the splint was brought to the mouth of the first bottle of hydrogen collected?
When the splint was brought to the mouth of the first bottle of hydrogen collected, the hydrogen gas ignited with a pop sound, indicating that hydrogen is a highly flammable gas. This reaction is due to the combination of hydrogen gas with oxygen in the air, creating water vapor.
Why is the volume of gas collected twice of the volume of other gas when electric current is passed through water?
When an electric current is passed through water, water is split into it's two component gasses- hydrogen and oxygen. You will get about twice as much hydrogen as oxygen- since water (H2O) has twice the hydrogen as oxygen.
