Mixtures and Pure Substances: Mixtures are physical combinations of two or more compounds or/and elements and are classified into. If it is a mixture, classify it as homogeneous or heterogeneous. A sample of wine consists of water, sugar, some amount of ethyl alcohol, and grape juice. Still, despite the differences in types, theres still a lot of chemistry in common. Answer: Pure substance:Table Sugar, Neon, Tungsten (W) Mixture:Beer, Chlorine bleach, Mixture: amixture is a substance which consist of two or more elements or com. A specific example is beta-damascenone. 2.36998061 : 2.37 Explain. Physical: A platinum ring becomes dull because of continued abrasion., Sugar dissolves in water. These are often charred oak barrels from the bourbon production industry, as regulations surrounding the production of bourbon dictate that barrels can only be used once. {"appState":{"pageLoadApiCallsStatus":true},"articleState":{"article":{"headers":{"creationTime":"2016-03-26T21:48:26+00:00","modifiedTime":"2021-07-21T21:47:43+00:00","timestamp":"2022-09-14T18:18:28+00:00"},"data":{"breadcrumbs":[{"name":"Academics & The Arts","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33662"},"slug":"academics-the-arts","categoryId":33662},{"name":"Science","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33756"},"slug":"science","categoryId":33756},{"name":"Chemistry","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33762"},"slug":"chemistry","categoryId":33762}],"title":"How to Distinguish Pure Substances and Mixtures","strippedTitle":"how to distinguish pure substances and mixtures","slug":"how-to-distinguish-pure-substances-and-mixtures","canonicalUrl":"","seo":{"metaDescription":"You can classify matter as a pure substance, or as a mixture.
