Two Types Of Mixtures A Heterogenous Mixture

Everything is made up of matter . Matter can either be a solid (example: gold), a liquid (example: hydrogen) or a gas (example: Hydrogen). Matter can be classified as either a mixture or a pure substance or a mixture. There are two types of mixtures a homogenous mixture and a heterogenous mixture. A homogenous mixture is a mixture that has been thoroughly combined and has been turned into a solution. A heterogenous is a mixture in which the particles has not been thoroughly combined. All mixtures can be separated to get the back to its original form - a pure substance. A pure substance is a type of substance that is made up of only one type of atom or one type of molecule. Examples of a pure substance can be oxygen gas, water , nitrogen gas, sugar and salt. Matter can also be classified as a mixture. A mixture is two or more substances combined to create a new substance an example of mixture would be oil and vinegar, Gatorade, coffee and salad. The metals that were used in the lab were , brass , copper, iron, and aluminum. Brass is not a pure substance because it is an alloy consisting of copper(cu) and zinc (zn). Copper is a pure substance and it is on the periodic table under the symbol Cu. Iron is also a pure substance and on the periodic table as Fe. Aluminum is another pure
Chemical property is when during a reaction the chemical composition has changed. Chemical properties cannot be observed by viewing or touching the sample of the material. Example of chemical properties are toxicity, which is when you determine how much of that substance can ruin plants, animals, organs or other organisms. Another example of a chemical property is heat of combustion, which means how much energy is released when the substance is burned with oxygen . More examples of chemical properties are flammability, reactivity with other chemicals , chemical stability and oxidation
