Is C2H2 a pure substance a homogeneous mixture or a heterogeneous mixture?
Neither. C2H2 is a compound (pure substance) so it is not a mixture at all. Hint: mixtures don't have chemical formulas.
Can a solution be heterogeneous?
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.
What is the difference in a pure substance and a mixture?
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.

Is a homogeneous mixture a substance?
AnswerNo It is not a pure substance because it contains more than one element.
How does heterogeneous mixture differ from a pure substance?
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.
Is top soil a pure substance?
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).
Is mineral water a pure water?

Is salt solution a pure substance?
No, a salt solution is not a pure substance. It is a mixture of salt (solute) dissolved in water (solvent). A pure substance contains only one type of element or compound with a fixed chemical composition.
