A ___________ means that 2 or more substances have combined, yet the 2 substances retain their chemical identity?
See your post above.
A mixture means that 2 or more substances have combined, yet the 2 substances retain their chemical identity.
A term that describes the situation where two or more substances have combined, yet each substance retains its chemical identity, is called a physical mixture. To understand this concept, you need to have a basic knowledge of chemical compounds and mixtures.
First, it's important to differentiate between chemical compounds and mixtures. Chemical compounds are substances that are made up of two or more different elements chemically bonded together. They have a specific chemical formula and properties that are unique to the compound. On the other hand, mixtures are combinations of two or more substances that are physically blended together but not chemically bonded. Each component of the mixture retains its individual properties.
In the case of a physical mixture, two or more substances are combined, but they do not undergo a chemical reaction. This means that the atoms or molecules of the substances do not rearrange themselves to form new substances. Instead, they are simply mixed together and can be separated by physical means.
For example, if you mix iron filings and sulfur powder, they will form a physical mixture called iron-sulfur mixture. While they can be blended into a single homogeneous mixture, the iron and sulfur retain their individual identities. You can easily separate the iron filings from sulfur powder using a magnet, as iron is magnetic while sulfur is not.
To summarize, a physical mixture is a combination of two or more substances where each component retains its chemical identity, and they can be separated by physical methods.
