What are the characteristic of pure substances?
The characteristics of pure substances are:fixed melting pointfixed boiling pointsfixed valencyfixed densitystability
What is a homogeneous mixture of two or more pure substances called?
solution
Compare and Contrast and How are a substance and a solution similar How are they different?
Substances and solutions are similar in that they both refer to forms of matter. However, a substance is a pure form of matter with consistent properties, while a solution is a homogeneous mixture composed of two or more substances. Solutions contain solutes dissolved in a solvent, whereas substances exist independently without being mixed with other components.
What is a pure substance that cannot be broken down into similar substances?
An element is a pure substance that cannot be broken down into simpler substances by chemical means.
What is a impure solution?
An impure solution is a mixture in which one or more substances are dissolved in a solvent. These substances are typically impurities that are not completely dissolved, leading to a solution that is not chemically pure.
Are pure substances homogeneous in appearance?
Yes, pure substances are generally homogeneous in appearance, meaning they have consistent properties throughout. This is because pure substances are composed of only one type of molecule or atom, leading to uniform characteristics such as color, texture, and composition.
Is juice an example of a molecule?
No it's a solution made from compounds derived from pure substances
Is sugar pure water a pure substance or a mixture?
cake
Is diamond a solution?
Diamond is not a solution in the typical sense. It is a crystalline form of carbon, not a homogeneous mixture of substances like a solution.
Is gold a solution?
No, gold is not a solution. Gold is a pure element and not a mixture of substances dissolved in a solvent.
Why these pure substances come up into mixtures?
Pure substances come up into mixtures because different substances can combine physically without undergoing a chemical reaction. These mixtures can be either homogeneous (uniform composition) or heterogeneous (non-uniform composition) depending on the interactions between the pure substances. Mixing pure substances allows for the creation of new materials with unique properties and characteristics.
What does it mean to say that a solution is homogeneous?
Homogeneous means that a material is the same throughout. Samples taken from any part of the material will be identical to one another. Elements and compounds are homogeneous pure substances. Solutions are homogeneous mixtures.
