A mixture of ice and water may be such example.
It is not a mixture if it does not contain at least two substances.
It can be heterogeneous if the two substances in the mixture don't mix together, such as sand and water. No: solutions must be homogeneous. If a mixture is heterogeneous, it is not a solution.
A pure substance is made out of only one kind of element (for example, gold is a pure substance). A mixture is made out of two or more different substances and is only combined by physical means. A pure substance cannot be broken down into a simpler substance. A mixture can be separated into its component parts.
Additional answer No, it's both. A mixture is a substance, and so is an element a substance. All matter is a substance whether it's a mixture or not.
A pure substance is a substance that consists solely of the same atoms/molecules.So a volume of water that contains only H2O is a pure substance. A block of iron that contains only Fe atoms is pure substance. A pure substance can be composed of atoms or molecules as I said before BUT they have to be exactly the same.A substance that has constant chemical composition and characteristics
A solution that negros have when ejaculating
No. A pure substance describes one that contains only one type of element/molecule. Mineral water is a mixture, since it contains many different types of minerals, next to water, and can therefore not be called a "pure" substance.
A homogeneous mixture is a mixture where the composition is uniform throughout, so it looks as if there is only one thing. A compound is a substance that contains two or more elements chemically combined in a fixed proportion. A pure substance is a substance that contains only one kind of matter.
In a homogenous mixture the substance are so evenly distributed that it is difficult to distinguish one substance in the mixture from another but it only contains only one substance and it will appear the same. In a heterogenous mixture the parts of the mixture are noticeably different from one another and the mixture is different and kind.
It is a mixture. A pure substance contains only one type of substance or one species of any substance or element. Sea water is a mixture of different salts dissolved in water. Thus, it is not a pure substance. Another point is that the different components of sea water can be observed separately.
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.
A mixture is not a pure substance since it contains various substances. A pure substance in one that is not mixed with any other thing.
A substance that contains only one type of atom is called an "element".
AnswerNo It is not a pure substance because it contains more than one element.
A heterogeneous mixture contains multiple chemical substances combined in a non-uniform way, whereas a pure substance contains molecules with only one chemical identity. For example, salt is a pure substance, whereas a mixture of salt an rocks is a heterogeneous mixture.
A mixture is multiple things mixed together - hence the name. A product with only one kind of substance is a "pure substance."
AnswerNo It is not a pure substance because it contains more than one element.
No, it contains many compounds and elements mixed in any ratio. It contains humus, and other particles including dirt. It is a mixture. A pure substance must contains only one type or atom (Element) or one type of molecule (compound).
