What is pure substance chemistry?
Pure substances are substances that are made up of only one kind of particles and has a fixed or constant structure. Pure substances are further classified as elements and compounds. An element is a substance that consists of only one type or kind of atom.
What is the 3 types of mixtures?
Mixtures can be classified on the basis of particle size into three different types: solutions, suspensions, and colloids. The components of a mixture retain their own physical properties.
What is an example of a liquid-liquid mixture?
This is a type of liquid-liquid mixture whereby the two substances mix completely to from a single substance. Examples are: Alcoholic drinks (alcohol mixed with flavorings). Juice (water mixed with flavorings).
What are examples of pure substances and mixtures?

| Can be categorised as elements and compounds. | Can be categorized as only homogeneous and heterogeneous. |
| Examples include Pure water, Hydrogen gas, Gold. | Examples include a mixture of Sand and Sugar, Oil and Water etc. |
What is a mixture answer?
A mixture is the physical combination of two or more substances in which the identities are retained and are mixed in the form of solutions, suspensions and colloids. … Some mixtures can be separated into their components by using physical (mechanical or thermal) means.
What is mixture Class 9?
A mixture is a substance which consist of two or more elements or compounds not chemically combined together. For Example Air is a mixture of gases like oxygen,nitrogen,argon,carbon dioxide etc. … The various substance present in a mixture are called as its constituents or components.
Which is a homogeneous mixture?
A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. … The amount of salt in the salt water can vary from one sample to another.
What type of mixture is a solution?
homogenous mixtures
Solutions are homogenous mixtures: particles of one substance (the solute) are mixed together with the particles of another substance (the solvent) – eg salty water. Heterogeneous mixtures: large aggregations (clumps) of the substances are mixed together – eg emulsions like oil in water.
What is difference between H * * * * * * * * * * mixture and heterogeneous mixture?
1. A homogenous mixture is that mixture in which the components mix with each other and its composition is uniform throughout the solution. A heterogenous mixture is that mixture in which the composition is not uniform throughout and different components are observed.
What is pure substance class 9?
A pure substance is a substance which has only one type of atoms or molecules thereby having a constant composition and structure. Complete answer: Substances which are made up of only one kind of atoms or molecules and have a definite composition throughout and have a fixed structure are known as pure substances.
What is mixture in Science Grade 7?
Mixture A mixture occurs when two or more pure substances are combined. A mixture can either be homogeneous or heterogeneous. An example of a homogeneous mixture would be sugar water. When sugar is added to water, it dissolves completely throughout the water. … An example of a heterogeneous mixture is sand and water.
What is homogenous and heterogenous mixture?
There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.
What is the difference between homogenous and homogeneous?
To summarise, Earlier, homogenous was used as a scientific term, mainly in biology, but now it is almost obsolete, being replaced by homologous. Whereas, homogeneous is a common word, very much in use and means having similar or comparable characteristics.
