Water is comprised of two parts hydrogen and one part oxygen, giving it the chemical formula H2O. Water is the most common chemical compound found on planet Earth and the most vital compound for the formation and survival of life. Bodies of water have many foreign components within them because water is a solvent that erodes at rock formations.Know More
Water itself is a very simple chemical compound, but it reacts to a wide variety of substances in ways that foster the formation of life. Water is found in many solutions, known as aqueous solutions, such as blood or digestive juices. The components found in a sample of seawater might be a mix of mostly water and mineral components evenly distributed and sparsely populated by biological matter like microbes or the traces of dead animals.
Water is a solvent, allowing it to break down various other substances into aqueous solutions, which has been vital in the formation of life. Life is thought to have first formed in an aqueous solution. The properties of water, such as the way it changes density to be lighter when frozen and how it accumulates in the air as clouds in its gaseous form, are some of the biggest reasons life thrives today.Learn more about Atoms & Molecules
Graphite is a mineral made of loosely bonded sheets of carbon atoms, giving it a slippery texture that makes it a very effective lubricant. This slippery quality also makes graphite a good material for pencil lead because it easily sloughs off onto paper.Full Answer >
An atom is comprised of a central portion called a nucleus that contains protons and neutrons. Electrons orbit the nucleus and are typically found in a one-to-one ratio with protons. Different stable atomic configurations are called elements. Hydrogen is unique in having one proton, one electron and no neutrons.Full Answer >
Plastics are comprised of a combination of elements such as carbon, silicon, nitrogen, oxygen, sulfur, chlorine and hydrogen. Carbon atoms form the backbone of most plastics, except the silicones, which have silicon as their base element. Plastics are polymers.Full Answer >
