Ammonia gas is collected in an inverted gas jar to take advantage of its lower density compared to air. This allows the gas to displace the air in the jar and fill it completely, ensuring an accurate measurement of the gas volume. Additionally, collecting the gas in an inverted jar prevents any leakage or loss of the gas during the collection process. Finally, the inverted jar setup also minimizes the risk of the gas coming into contact with any moisture or impurities present in the surrounding environment, ensuring the purity of the collected gas sample.

RafaAmmonia gas is collected in an inverted gas jar to prevent it from escaping into the surrounding atmosphere. Since ammonia is lighter than air, collecting it in an inverted jar ensures that it is trapped in the jar due to its lower density. This setup allows for safe and efficient collection of the gas for various laboratory purposes.

Give a reason why it is necessary to leave the gas jar undisturbed in a soil profile activity?
Leaving the gas jar undisturbed in a soil profile activity ensures that any gas released from the soil is accurately captured and measured. Disturbing the gas jar can lead to loss of gas or inaccurate results, affecting the analysis of the soil's gas composition.
Bromine gas is put into 1 jar and then a gas jar of air is placed over it after a few minutes the bromine gas can be seen filling both gas jars why?
This happens due to diffusion, where the bromine gas molecules move from a region of high concentration (in the first jar) to a region of low concentration (in the second jar containing air). Over time, the bromine gas spreads out evenly in both jars until equilibrium is reached.
Is air sealed in a jar a gas?
Yes, air in a sealed jar is a mixture of gases, including nitrogen, oxygen, carbon dioxide, and other trace gases. These gases exert pressure on the walls of the jar, even though they are invisible.
Why collect hydrogen gas in a test tube rather than glass jar?
Hydrogen gas is less dense than air and tends to rise quickly, so collecting it in a test tube allows for easier capture and observation of the gas. Additionally, a test tube typically has a smaller opening, which reduces the risk of the gas escaping. Finally, a test tube is easier to handle and transport compared to a larger glass jar.
I smelled too much ammonia in the lab today and it was like 50 ml jar and I'm having headache is there any danger?
Inhaling high levels of ammonia can cause headaches, nausea, and irritation of the nose and throat. It is important to ventilate the area well and seek fresh air. If symptoms persist or worsen, seek medical attention.
