Which material has definite properties and definite chemical composition?
Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
What examples are there for homogeneous solid?
Examples of homogeneous solids include pure metals like gold, iron, and copper, as well as pure crystalline compounds like table salt (sodium chloride) and sugar. These materials have a uniform composition and properties throughout their structure.
What is the homogeneous material with with a variable composition?
An example of a homogeneous material with a variable composition is a solution, where one or more substances are dissolved in another substance. The composition of a solution can vary depending on the amount of solute dissolved in the solvent.
Is air an example of pure substance?
No. Air is not pure substance. Air has all dust and dangerous gases with it. From place to place its composition changes.
What is a pure soild?
A solid is a material that is not Gas or Liquid. "Pure" indicates that has no impurities or other metals. For example, gold can be made so that it is 99.9% pure. Answer: There are a lot of things that can be Solid and not a mixture.
Is a sample of pure solid chromium is homogeneous?
Yes, a sample of pure solid chromium would be considered homogeneous because it consists of a single element (chromium) uniformly distributed throughout the sample. This means that there would be a consistent composition and properties throughout the material, making it homogeneous.
Which is a property of a pure substance uniform composition fixed composition varying composition?
A property of a pure substance is fixed composition. This means that the substance is made up of only one type of molecule or atom throughout, with no variation in its chemical composition.
Which product exhibits the properties of metal and non metal?
The properties of a metal are of follows, a pure chemical composition, a pure chemical composition is a element, or a compound in pure form. As well as a metallic luster (when it is shiny and if melted or filed flat it looks like a mirror. Now pure chemical composition is hard to test with solid metal, but a metallic luster should do the trick usually, and if it is being melted, than you should see that is is a pure chemical composition by looking if parts of it have different melting speeds.
Which is not a property of a pure substance uniform composition varying composition fixed composition?
The property that is not characteristic of a pure substance is "varying composition." A pure substance has a fixed composition, meaning it has a consistent and definite chemical makeup throughout. In contrast, substances with varying composition are mixtures, which can contain different amounts and types of components.
What are 2 pure substances?
A pure substance is a homogeneous chemical substance which means its composition is constant and its properties are consistent too. Some examples of this kind of substances are water, baking soda and sucrose.
Which is not a property of a pure substance fixed composition uniform composition varying composition?
A pure substance has a fixed composition and uniform composition, meaning it consists of only one type of particle and its properties do not change regardless of the sample size. Therefore, varying composition is not a property of a pure substance, as it implies the presence of multiple substances or mixtures.
What solid homogeneous inorganic substance has a specific chemical composition and atomic structure?
This question has a bit of ambiguity. Any material with a particular chemical makeup and an orderly arrangement of atoms is called a crystal. However, restricting the question to inorganic solid materials, probably means the best answer is mineral.
