What else can I help you with?
Is air heterogeneous mixtures or homogeneous mixture?
Air is considered a homogeneous mixture because it contains a uniform distribution of different gases (such as oxygen, nitrogen, and carbon dioxide) throughout. This means that regardless of where you sample air from, the composition will be the same.
Is air in a sealed flask homogeneous?
Yes, air in a sealed flask is considered homogeneous because it is a mixture of gases (such as nitrogen, oxygen, carbon dioxide) that are uniformly distributed throughout the container. This means that any part of the air sample will have the same composition as any other part.
How do you distinguish between nitrogen oxide and oxygen using a chemical test?
One way to distinguish between nitrogen oxide and oxygen is by using a glowing splint test. When a glowing splint is introduced to a gas sample, oxygen will relight the splint due to its ability to support combustion, while nitrogen oxide will not. Additionally, nitrogen oxide can be detected using a brown ring test with iron(II) sulfate and sulfuric acid, where a brown ring forms at the junction of the two layers if nitrogen oxide is present.
Is a sample of pure solid chromium is homogeneous?
Yes, a sample of pure solid chromium would be considered homogeneous because it consists of a single element (chromium) uniformly distributed throughout the sample. This means that there would be a consistent composition and properties throughout the material, making it homogeneous.
Is carbon monoxide homogeneous or heterogeous?
Pure carbon monoxide, like any other pure compound, is homogeneous.
When nitrogen gas is added to a sample of neon gas in a closed container the pressure inside the container?
increases
Is air heterogeneous mixtures or homogeneous mixture?
Air is considered a homogeneous mixture because it contains a uniform distribution of different gases (such as oxygen, nitrogen, and carbon dioxide) throughout. This means that regardless of where you sample air from, the composition will be the same.
Is a sample of N2 Gas a homogeneous mixture?
The symbol N2 is for the diatomic molecule of nitrogen; it is not a mixture.
Is air in a sealed flask homogeneous?
Yes, air in a sealed flask is considered homogeneous because it is a mixture of gases (such as nitrogen, oxygen, carbon dioxide) that are uniformly distributed throughout the container. This means that any part of the air sample will have the same composition as any other part.
How do you frozen plant sample in liquid nitrogen?
To freeze a plant sample in liquid nitrogen, first place the sample in a container suitable for cryogenic temperatures. Submerge the sample in liquid nitrogen gradually to prevent splashing. Ensure the sample is completely frozen before transferring it to a long-term storage container for storage at ultra-low temperatures.
How many milliliters of nitrogen and oxygen are in a one liter sample of dry air?
In a one liter sample of dry air, there are approximately 780 mL of nitrogen and 210 mL of oxygen. Nitrogen makes up about 78% of dry air while oxygen makes up about 21%.
Is water a heterogeneous or homogeneous?
Water is a homogeneous mixture because it is a uniform combination of hydrogen and oxygen molecules. Each part of a sample of water, regardless of where it comes from, has the same composition and properties.
What isa homogeneous mixture?
A homogeneous mixture have a constant ratio of solute to solvent. Just by looking at the sample a person cannot tell the difference in the composition because it is going to be same. Air is a good example of homogeneous mixture. The composition of air would be same at any place. (78% Nitrogen, 21% Oxygen, little bit of Argon, some CO2 and other gases in very trace quantities).
How do you distinguish between nitrogen oxide and oxygen using a chemical test?
One way to distinguish between nitrogen oxide and oxygen is by using a glowing splint test. When a glowing splint is introduced to a gas sample, oxygen will relight the splint due to its ability to support combustion, while nitrogen oxide will not.

Is carbon monoxide homogeneous or heterogeous?
Pure carbon monoxide, like any other pure compound, is homogeneous.
When nitrogen gas is added to a sample of neon gas in a closed container the pressure inside does what?
It rises, because you have packed more atoms into the same space.
