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.
impure because they are made of more than 1 substance
A compound can be pure if it consists of only one type of molecule. If a compound contains more than one type of molecule or impurities, then it is considered impure.
A pure substance has a specific density that remains constant regardless of the amount of substance present. An impure substance may have a density that varies depending on the amount and type of impurities present in the substance.
No, a suspension is not a pure substance. It is a mixture of particles dispersed in a liquid, where the particles are not fully dissolved and can be seen with the naked eye.
A pure substance typically has a higher melting point than an impure substance. Impurities disrupt the regular arrangement of particles in the substance, making it more difficult for them to overcome the intermolecular forces and transition from solid to liquid state. This results in a lower melting point for impure substances.
If a substance in a mixture is preponderant--, if the amount far exceeds the amounts of the other substances in the mixture it is usually called an impure substance. Resource: Separation of the Components of a Mixture Lab -Chemistry
impure because they are made of more than 1 substance
A substance might be pure with a single compound or impure with impurities along with principal compounds.
If there is no salt or substance that makes it impure it is a pure mixture
Yes Baking Powder Is A Pure Substance.
A compound can be pure if it consists of only one type of molecule. If a compound contains more than one type of molecule or impurities, then it is considered impure.
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.
A pure substance has a specific density that remains constant regardless of the amount of substance present. An impure substance may have a density that varies depending on the amount and type of impurities present in the substance.
A pure substance is one which contains only that substance and nothing else. An impure substance contains other substances in varying amounts.
A pure substance will melt over a very narrowtemperature range.An impure substance will melt over a broader, lower temperature range.
No, a suspension is not a pure substance. It is a mixture of particles dispersed in a liquid, where the particles are not fully dissolved and can be seen with the naked eye.
yes water is mixture of many impure substances and bacteria.even pure water has some bacterias.
