Some disadvantages of upward delivery gas collection include the potential for gas leakage due to the method's reliance on the buoyancy of the gas, limitations in the amount of gas that can be collected compared to other methods, and the need for proper sealing and maintenance of the collection system to prevent issues. Additionally, the efficiency of upward delivery gas collection may vary based on factors such as environmental conditions and gas composition.

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.
How is ammonia gas collected in the laboratory preparation of ammonia gas?
Ammonia is collected in the laboratory by upward delivery and downward displacement of air....
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 hydrogen gas collected by upward delivery?
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
What is the upward force that is exerted by a gas or liquid called?
well The upward force of a liquid or gas on an object is called
A gas is a collection of what that move about freely?
Gas is a collection of gas phase particles that move around freely. The gas phase particles are ions, molecules or atoms.
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.
The upward push on an object by liquid or gas it is placed in is its?
Buoyancy:)
What are three methods of collecting gas?
1st:Upward delivery.. 2nd:Downward delivery.. 3rd:Displacement..
How can chlorine gas be collected?
By downward delivery. (:
Do pizza delivery get reimbursed for gas?
In general, no.
Describe what happens to gas molecules when air is heated?
The gas molecules go upward. Sorry I dont have any more information but this was all I ould find out
