It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
Pure argon gas is a homogeneous substance.
Yes, Argon (Ar) is an mono-atomic elementary gas, so it's PURE
The two types of mixtures is heterogeneous and homogeneous. Heterogeneous mixtures are two or more substances combined but not chemically. You can see the two substances. Homogeneous mixtures are two or more substance that are chemically combined. You are not able to see the different substances; they appear as one.
No. It is an element, which is homogeneous matter.
Ammonia is a compound, not a mixture. Household ammonia is a homogeneous mixture of ammonia and water.
Helium is an element which makes it a pure substance.
Neither. Helium is not a mixture at all, it is a pure substance.
Neither. Helium is not a mixture at all, it is a pure substance.
Pure argon gas is a homogeneous substance.
Yes, Argon (Ar) is an mono-atomic elementary gas, so it's PURE
Cider vinegar is not a pure substance it is a mixture. It contains water, acetic acid and flavouring agents. As there is only one phase present ie no gas or solids it is a homogeneous mixture.
All the elements are homogeneous so the oxygen is homogeneous, too.
If the sugar does not dissolve it the oil, then it is not
A homogeneous substance is the same throughout. So, a bar of pure gold, a diamond, pure water, saline water (water with salt dissolved in it) and nitrogen gas are all homogeneous, as they consist of the same substance(s) throughout. In other words, they are regular.So, you could say that a homogeneous substance is a puresubstance.
Steam (water as a gas) is homogeneous.
The two types of mixtures is heterogeneous and homogeneous. Heterogeneous mixtures are two or more substances combined but not chemically. You can see the two substances. Homogeneous mixtures are two or more substance that are chemically combined. You are not able to see the different substances; they appear as one.
A type of mixture in which different materials are spread out unevenly is known as a heterogeneous mixture. It is a combination of substances with no uniform composition or properties.
