Mixture – is a combination of two substances in such a way that no chemical reaction occurs between the components and you can separate them again. A mixture is a material system made up of two or more different substances which are mixed but are not combined chemically. The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation.

Examples of Mixtures sand and water salt and water sugar and salt
Elements are chemically the simplest substances and hence cannot be broken down using chemical methods. Elements can only be changed into other elements using nuclear methods. An element is a type of matter composed of atoms that all have exactly the same positive charge on their nuclei. In other words, all atoms of an element have the same
Examples of Elements
aluminum, selenium, zinc, magnesium, carbon, mercury, gold, arsenic, lead and sodium.

Compound is a chemical species that is formed when two or more atoms join together chemically, with covalent or ionic bonds. A compound is a substance formed when two or more chemical elements are chemically bonded together.
Chemical compounds can be broadly classified into two categories, namely, organic compounds and inorganic compounds.

Organic compounds are complex compounds of carbon in which one or more atoms of carbon are covalently linked to atoms of other elements, such as hydrogen, nitrogen, and oxygen. Hydrocarbons are organic compounds that are made up of carbon and hydrogen atoms only.

Hydrocarbons are further classified into alkanes, alkenes, alkynes, and aromatic hydrocarbons....

Engineering Overview

...Engineering Overview The Field Engineers apply the theories and principles of science and mathematics to research and develop economical solutions to technical problems. Their work is the link between perceived social needs and commercial applications. Engineers design products, machinery to build those products, plants in which those products are made, and the systems that ensure the quality of the products and the efficiency of the workforce and manufacturing process. Engineers design, plan, and supervise the construction of buildings, highways, and transit systems. They develop and implement improved ways to extract, process, and use raw materials, such as petroleum and natural gas. They develop new materials that both improve the performance of products and take advantage of advances in technology. They harness the power of the sun, the Earth, atoms, and electricity for use in supplying the Nation's power needs, and create millions of products using power. They analyze the impact of the products they develop or the systems they design on the environment and on people using them. Engineering knowledge is applied to improving many things, including the quality of healthcare, the safety of food products, and the operation of financial systems. Engineers consider many factors when developing a new product. For example, in developing an industrial robot, engineers determine precisely what function the robot needs to perform; design and test the robot's components; fit the...
