Give to point of difference between mixture and compound
Answers
If you're trying to find a way to remember how to tell compounds from mixtures, just remember that compounds don't have variable composition and mixtures do. For example, water is always composed of two hydrogen atoms and one oxygen atom per molecule. Every particle of water in a sample is identical. Compounds are made of identical molecules. Mixtures, on the other hand, are made of more than one type of particle mixed together so the composition can vary. Rubbing alcohol can be obtained as 70% isopropanol/30% water and as 90% isopropanol/10% water. Any proportion of water and alcohol is possible as they completely dissolve in all proportions. Salts have limited solubility in water, but their proportions can still vary. An an example, the salinity of ocean water varies by location.
