Mixtures Fixed boiling points Working scientifically Test your knowledge Key points Most materials that we use are mixtures , and just a few are pure elements or pure compounds. 1: Mixtures are useful when you want to combine elements of multiple materials into one product. Chemical compounds are very different from mixtures: The elements in a chemical compound can only be separated by destroying the compound. Air. Sometimes the individual pure substances are more important than the mixture. Mixtures with uniform compositions are also called homogeneous mixtures; non-uniform composition mixtures are called heterogeneous mixtures. It is actually the physical combination of two or more substances that are able to retain the identities while they are mixed in form of solutions, suspensions or colloids. Has a strong pungent smell and is used to kill clothes moths and fabric pests. (Answer: It is a mixture because the sand and the water stay separate. To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase.

In simplest terms, a chemical change (or chemical reaction) occurs when two substances are mixed together and transform into a third substance. Heterogenous mixtures can be separated using following methods: filtration (seeping) solids are retained on the sieve, drain or filter; this process can be observed by straining pasta on asieve; sedimentation gravitating of solid substances to the bottom under the influence of gravity; it is used in sewage treatment plants; decantation pouring off the liquid, leaving the sediment behind; it can be observed during draining off potatoes after being boiled or poring off the tea or coffee and leaving the leaves or coffee grounds behind; Homogenous mixtures can be separated using following methods: vaporizationevaporationvaporization heating up the liquid mixture and the solid dissolved in it to evaporate the liquid; this process is used in the preparation of jam, while in countries with awarm climate it is the effect of evaporation of sea water and the formation of rock salt deposits; crystallizationcrystallizationcrystallization this technique allows the separation of solid crystals from the solution; Before watching the movie Separating the mixture of sulphur and iron, formulate aresearch question and hypotheses. This distribution is merely proportional, and the majority substance acquires the name of solvent while the minority is called solute.
