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 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.
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.
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.
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.
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 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.
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.
How are liquid gold and solid gold alike?
Liquid gold and solid gold are both forms of pure gold. The difference is their physical state - liquid gold is molten gold at a high temperature, while solid gold is cooled and solidified gold at room temperature. Both forms have the same chemical composition and properties as pure gold.
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.
What property of pure substance is similar to solution?
Both pure substances and solutions have specific physical and chemical properties that are unique to their composition. Both can exist in different phases (solid, liquid, gas) and exhibit properties such as boiling point, freezing point, density, and solubility that are characteristic of their chemical makeup. Additionally, both pure substances and solutions can undergo physical changes such as melting, boiling, and dissolving without changing their chemical composition.
