1. Is A Soft Drink A Mixture

A carbonated soft drink is a 'homogeneous' mixture, which is a combination of substances that has uniform composition and properties; a mixture that is uniform throughout. Claire Bonnet 0 2 years ago Cincinnati, OH. Aug 25, 2011 Is uranium a substance or mixture? A carbonated soft drink a mixture homogeneous if under pressur and no. Is white sugar a pure substance or mixture?

Concrete is a mixture of lime, water, cement, sand and rocks. When these components are mixed together, the cement solidifies, forming a solid mixture. Although the hardening of the cement can be considered a chemical reaction, the actual mixture is held together by a physical force, and these components are still not chemically bonded. Alloys are also considered as mixtures. Alloys are homogeneous mixtures of two or more kinds of metal. Brass is a mixture of 70 percent copper and 30 percent zinc.

Bronze is 90 percent copper and 10 percent tin. Alloying metals is like dissolving one metal into another in order to improve its properties.

It is just like dissolving salt in water, which is why alloys are considered to be a mixture rather than a compound. Another example of solid mixtures are precious stones like amethyst, topaz, opal and garnet. These stones are a combination of silicon dioxide and different kinds of metals.
