No, only those that do not dissolve in water, or they will dissolve in the water rather than bubble through it to be collected. Examples of gases that can be collected over water include:- Hydrogen, nitrogen, oxygen (only slightly soluble), methane, carbon monoxide. Examples of gases that can just be collected over water (quie soluble - so much will be dissolved in the water as well):- Nitrogen dioxide, carbon dioxide, chlorine Examples of gases that are too soluble to be collected over water:- hydrogen chloride, ammonia (which is the most soluble of all gases) Both of these gases are collected by displacement of air - hydrogen chloride by the gas jar being held as in a glass - with the base on the table - because it is heavier than air (chlorine and carbod dioxide can be collected like this too) and and ammonia by the gas jar being held upside down to trap the ammonia (as it is lighter than air).

Why is it that HCL gas cannot be collected over water?
Hydrochloric acid (HCl) gas is highly soluble in water, meaning it will readily dissolve in water to form hydrochloric acid solution. This will make it difficult to collect pure HCl gas, as it will mix with the water and form an acidic solution. In addition, the reaction between HCl gas and water can generate heat, which may lead to a dangerous build-up of pressure in the collection vessel.
Why is it helpful for a gas collection tube to be dry?
1. Gas in the tube may diffuse into the water droplets in the tube. 2. It may affect the volume count in the collection tube. 3. Some substances are sensitive to water and may give different results when water is present
What happens to the gas collected in the inverted funnel of sublimate?
The gas collected in the inverted funnel of sublimate would be trapped there until it can be released or transferred for further analysis. The gas may undergo further reactions or be used in various experiments depending on the specific context in which it was collected.
Why are the first bubble allowed to escape in water displacement method in collecting hydrogen gas?
In the water displacement method for collecting hydrogen gas, the first bubble is allowed to escape because it may contain air or other gases present in the apparatus or reaction mixture. Allowing this bubble to escape ensures that only pure hydrogen gas is collected in the inverted container. This helps to obtain accurate measurements and prevent contamination of the collected gas sample.
Is using a measuring cylinder or gas syringe better to use when the gas is soluble?
Using a gas syringe is typically better when the gas is soluble because it allows for direct measurement of the volume of gas collected without worrying about gas dissolving in the liquid. Measuring cylinders, on the other hand, may result in inaccurate readings due to the dissolution of gas in the liquid.
Why is ammonia gas not collected over water?
Ammonia gas reacts with water to form ammonium hydroxide, a basic solution. This reaction reduces the amount of ammonia gas collected and may lead to inaccuracies in the experimental results. To prevent this, ammonia gas is typically collected using an alternative method such as downward displacement of air or through a gas syringe.
Why is it that HCL gas cannot be collected over water?
Hydrochloric acid (HCl) gas is highly soluble in water, meaning it will readily dissolve in water to form hydrochloric acid solution. This will make it difficult to collect pure HCl gas, as it will mix with the water and form an acidic solution. In addition, the reaction between HCl gas and water can generate heat, which may lead to a dangerous build-up of pressure in the collection vessel.
Why is hydrogen chloride not collected over water?
Hydrogen chloride is soluble in water, so attempting to collect it over water would result in a significant amount of the gas being lost as it goes into an aqueous solution that will soon become dangerously acidic.
Why is it helpful for a gas collection tube to be dry?
1. Gas in the tube may diffuse into the water droplets in the tube. 2. It may affect the volume count in the collection tube. 3. Some substances are sensitive to water and may give different results when water is present

Is hot water included in the gas bill?
Hot water may or may not be included in the gas bill, depending on how your home is set up. Some homes have a gas water heater that is connected to the gas bill, while others may have a separate arrangement for hot water. It's best to check with your utility provider to confirm what is included in your gas bill.
When is francium a gas?
At a temperature over 677 0C francium may be a gas.
Why are the first bubble allowed to escape in water displacement method in collecting hydrogen gas?
In the water displacement method for collecting hydrogen gas, the first bubble is allowed to escape because it may contain air or other gases present in the apparatus or reaction mixture. Allowing this bubble to escape ensures that only pure hydrogen gas is collected in the inverted container. This helps to obtain accurate measurements and prevent contamination of the collected gas sample.
Can pure water be extracted from skim milk?
Yes. The water may be boiled off or evaporated by heating in the usual manner, and then collected on glassware.
Is it safe to drink air conditioner water?
No, it is not safe to drink water that has collected in an air conditioner as it may contain harmful bacteria and chemicals.
What may have oceans to form as Earth's atmosphere changed?
Oceans formed on Earth as its atmosphere cooled and water vapor in the atmosphere condensed into liquid water, which then collected in low-lying areas to form bodies of water. Over time, continuous rainfall helped to fill these bodies of water, eventually forming oceans.
If my gas gets turned off, will I still have hot water available?
If your gas gets turned off, you may not have hot water available because most water heaters rely on gas to heat the water.
