What advantage does an impure mixture have over pure substance?

∙ 7y ago
Generally an impure material is cheaper than a pure material; the word advantage is not so adequate here - can use pure or impure, this depends on the specific applications.

Why does a pure substance cost more than an impure substance?
It depends on what you're trying to accomplish. Helium is a pure substance. Corn flakes are a mixture. If you're trying to blow up balloons, the pure substance has one huge advantage over the mixture: balloons filled with corn flakes are no fun. But if it's 6 am and you want to eat breakfast, you'd better stick to the mixture.
How do you distinguish a pure substance?
A pure substance will melt over a very narrowtemperature range.An impure substance will melt over a broader, lower temperature range.
If you had a single pure mystery substance and cut it half over and over again until you eventually had two other different mystery substances the original substance would have been a?
mixture
What is the difference between pure and impure substances?
a pure substance is one which only contains one type of atom/molecule and an impure substance is one the has numerous types of atoms/molecules, but the impurites generally dont amount to over 50% of the substance's mass.
What is the differences between a mixture and a pure substance?
1. A mixture contain two or more substances. 2. A mixture can be separated in components by physical procedures.
How do you identify a pure substance?
1. Check the melting point or boiling point of the substance. E.g. it is known that the boiling point of water is 100 degree celcius. It a sample of water boils are 101 degree celcius, the sample is impure. 2. Check if melting or boiling occur over a range of temperatures. E.g. if water boils from 101 to 103 degree celcius, then it is impure because pure water boil exactly at 100 degree celcius. 3. Perform paper chromatography. If the sample has only one spot on the chomatogram then it is pure substance.
What are ways to separate a mixture?
If you want to separate a mixture, you can: 1) evaporate away a substance and you will most likely have a residue left over 2) you can use a filter 3) check for magnetic particles and take them out I hope this answers your question!
What is a heterogeneous mixture?
A heterogeneous mixture is a mixture when two or more substances are mixed together but aren't chemically combined/joined
What is a mixture?
A substance composed of 2 (two) or more elements (compounds) that are physically mixed together but not chemically combined.For instance:salt and sugar crystalsiron filings and sandoil and water
The main advantage of ECL over TTL?
The main advantage of ECL over TTL is speed.
How do you know if a sample of matter is a mixture?
A substance is scientifically defined as matter the has the same composition and properties throughout, so substances are elements and compounds. Mixtures are not considered substances. However, if we are taking the word substance to simply mean "something" as in everyday (and not purely science-based) use, then one could use the following criteria: A compound is a substance whose smallest unit is made up of atoms of more than one element chemically bonded together, such as carbon dioxide (CO2), water (H2O), sugar (C6H12O6), and ammonia (NH3). A pure sample of a compound will appear the same throughout, and always occurs in specific proportions of its constituents. For example, pure sugar is always composed of molecules of C6H12O6 and always occurs in that proportion--6 atoms of Carbon, 12 atoms of Hydrogen, and 6 atoms of Oxygen. Compounds can only be formed or broken down through a chemical reaction. A mixture is a combination of substances (elements or compounds) can either be homogeneous or heterogeneous. Heterogeneous mixtures do not look the same throughout, so they are easily distinguished from compounds. Homogeneous mixtures (or solutions), like tea, Kool-Aid, blood, brass, and sugar water, are only physically bonded together and can be separated through physical means.
Is Ibuprofen a mixture or pure substance?
Ibuprofen is just a brand name for the actual chemical, an aromatised propanoic acid, which gives the desired pain relief effect. Most commercially available ibuprofen, in painkillers, is often sold in a mixture with paracetamol and caffeine so that the pain relief effects are felt faster. So in answer to your question Ibuprofen itself is a pure substance, but most over-the-counter Ibuprofen tablets etc are sold as mixtures with other pain relievers and caffeine.
