Question

Can oxygen whose relative molecular mass is 32 be collected by downward delivery? If either yes or no, explain your reason.

Answer 1

Step-by-step explanation:

No, oxygen with a relative molecular mass of 32 cannot be collected by downward delivery. The reason for this is that oxygen is a gas at standard temperature and pressure (STP). Gases have the tendency to rise due to their low density compared to the surrounding air.

Downward delivery is a method of collecting gases by allowing them to flow downward into a container. However, since oxygen is lighter than air, it will tend to rise instead of flowing downward. This is because oxygen molecules have a lower mass and occupy a greater volume compared to the same number of air molecules.

To collect oxygen, a different method such as upward displacement or the use of a gas syringe is typically employed. In upward displacement, the oxygen is collected by displacing a less dense gas, such as air, from the container. This allows the denser oxygen gas to fill the container. In the case of a gas syringe, the oxygen can be directly drawn into the syringe by creating a vacuum or using a piston.

Therefore, due to the nature of gases and the behavior of oxygen, it cannot be effectively collected by downward delivery.

Answer 2

So...yk

Step-by-step explanation:

Since the water is displaced downward by the gas collecting in the jar , the process is called downward of water, The reason are:

1. Oxygen is only slightly soluble in water. Therefore it can be collected over water without fear of excessive dilution.

2. Oxygen is slightly heavier than air, so it cannot collected over air.
