Well, darling, let me break it down for you. The disadvantages of upward delivery gas collection include the risk of leaks due to improper seals, potential corrosion issues from exposure to the elements, and the hassle of maintenance and repairs in hard-to-reach areas. So, if you're thinking about going up, just remember that what goes up must come down... for maintenance.
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.
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.
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).
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.
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.
well The upward force of a liquid or gas on an object is called
Methane is insoluble in water, and it is less dense than air. Introduce moist methane via a delivery tube from one end of U shaped tube. The u shaped tube should contain fused calcium chloride. Dry methane can then be collected from the other end of the u shaped tube.
Delivery includes hook up. It did with ours.
The upward push on an object by liquid or gas it is placed in is its buoyant force. This force is equal to the weight of the fluid displaced by the object.
it gives me gas
