A compound is a substance
A compound is a substance created by when two or more chemical elements are bound together. There are so many examples of a compound that are used on regular basis including sodium chloride (NaCl, a common salt use at every place), sodium chloride (Na2CO3, commonly found in manufacturing paper, soap, glass, and photography). Types of compoundsThe type of bonds holding together in a compound can vary i.e. covalent bonds and ionic bonds. Therefore, there are a lot of changes in the chemical properties and structures producing different types of compounds. But typically the elements are present in a fixed ratio whether it is available in any compound. There are some examples of the compound mentioned below that help to understand you in a good manner.Examples of CompoundsA few examples of compounds are given below.Pure water - It is a compound made from two elements, i.e., hydrogen and oxygen. In which each molecule of water contains 2 hydrogen atoms bonded to a single oxygen atom. In simple words, the ratio of hydrogen to oxygen in water is 2:1. Pure Methane - This compound is also made up of two elements- carbon and hydrogen in the ratio of 4:1.Pure table salt - The two elements present in pure table salt are sodium and chlorine. However, these two elements share an equal ratio, i.e., 1:1.Pure Glucose - This is the compound that is made from three elements, i.e., carbon, hydrogen, and oxygen. Hydrogen shares a double ratio than carbon and oxygen - 2:1:1. What is a Mixture? A mixture is a substance composed of two or more matter that can be separated with the help of physical methods. There are some examples of the mixtures that are present around you like a solution of water and salt, sugar and water, different gases, air in the atmosphere and many more. Below are some other examples of a mixture.
