Liquid air is a mixture not a compound.
As we know that air is a mixture of different gases. It contains 78% nitrogen and 21% oxygen and remaining 1% is comprising various other gases.
The process of preparing liquid air does not involve any chemical reaction and hence no compound is formed. It is basically a physical process involving compression of air as well as cooling simultaneously. Thus liquid air remains a mixture.
A solid can be any one of these, although you will probably see mixtures being more liquids and gasses. It is not the state of matter that makes it compound, element, or mixture, but what composes it.
Matter is the general name given to any material or substance on Earth. Usually we read statements like: "All matter is made up of atoms". Another statement in science texts is: "Matter is anything with mass".
So water is matter, air is matter, oxygen is matter. They all have mass.
Water is a compound, air is a mixture and oxygen is an element.
Matter can be an element, or a compound, or a mixture.
No because a compound is not alike a mixture of two or more element. In a compound , the atoms of two or more elements are joined together to form a new substance that is different from its ingredients.
It can be anything. A substance can be described as any material regardless of what it is made of.
A pure substance is either an element or a compound.
It depends on the substance your are talking about. It could be a compound, mixture, or substance; depending on the substance. If it is an element off the periodic table, it is an element. If it is two elements chemmically combined, it is a compound. If it is two elements that are not chemically combined, it is a mixture.
Barium is an element from the periodic table therefore it is neither a mixture or a compound
Is gasoline a element a mixture or a compound
No. Sulfur dioxide is a compound, which makes it a pure substance, not a mixture.
electricity is not a compound, mixture or element.
A pure substance is either an element or a compound.
A mixture of oil and water is a mixture, not an element. If by substance you mean not a pure substance (element or compound), then oil and water would be a substance (that is a mixture). If you mean oil and water separately, then oil is a mixture of hydrocarbons, and water is a compound (pure substance).
This substance is a compound.
I think it's a mixture.
If something is not a mixture then it is a pure substance, either an element or a compound.
Steel is an alloy- which is a compound, or intermixture. So it is not an element or pure substance.
Pure substance.
It depends on the substance your are talking about. It could be a compound, mixture, or substance; depending on the substance. If it is an element off the periodic table, it is an element. If it is two elements chemmically combined, it is a compound. If it is two elements that are not chemically combined, it is a mixture.
Only a substance can be categorized as an element, a compound, or a mixture. An ink pen is not a substance, it is an implement.Added:The 'ink' (IN a pen) is definitely a mixture,not an element or pure compound.
Pure sugar is a substance (compound).
yes
Barium is an element from the periodic table therefore it is neither a mixture or a compound
