Water is one of the few known substances whose solid form is less dense than the liquid. The plot at the right shows how the volume of water varies with the temperature; the large increase (about 9%) on freezing shows why ice floats on water and why pipes burst when they freeze.The two elements that make up a molecule of water are hydrogen and oxygen; there are two hydrogen atoms and one oxygen atom, resulting in the chemical formula H2O. Hydrogen and oxygen bond together due to the number of electrons in their orbitals.The mRNA. Pfizer's vaccine is the first on the market that consists of actual genetic information from a virus in the form of messenger RNA, or mRNA, a type of molecule whose usual job is toWater (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds.9 Common Chemicals in Tap Water. Chlorine - Chlorine is added to drinking water by many municipal water systems as a purification technique. However, it can be absorbed through physical consumption and through your skin while bathing. Fluoride - Fluoride has been added to tap water for decades to help reduce tooth decay.

What Elements Make up Water? - Reference.com

Seawater, water that makes up the oceans and seas, covering more than 70 percent of Earth 's surface. Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases.Everything is made of atoms. An atom is the smallest particle of an element, like oxygen or hydrogen. Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That's why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.Many things like salts, sugars, acids, bases, and other organic molecules can be dissolved in water. Pollution of ocean water is a major problem in some areas because many toxic substances easily mix with water. Figure 14.4: Ocean water is composed of many substances. The salts include sodium chloride, magnesium chloride, and calcium chloride.What substances make up water ? H2o , hydrogen for every oxygen pure substances. What substances make up an iron pot ? Iron. What is an element ? Elements are pure substances that are made up of one kind of atom. What 2 kinds of atom does water contain ? Oxygen and Hydrogen .

What are the ingredients of Pfizer's covid-19 vaccine

Just iron. Elements are pure substances that are made up of one kind of atom. Pizza is not an element because it is a mixture of many substances. Water is a pure substance, but it contains two kinds of atom: oxygen and hydrogen.Urine is a liquid by-product of metabolism in humans and in many other animals. Urine flows from the kidneys through the ureters to the urinary bladder. Urination results in urine being excreted from the body through the urethra.. Cellular metabolism generates many by-products that are rich in nitrogen and must be cleared from the bloodstream, such as urea, uric acid, and creatinine.1 decade ago. Favorite Answer. Iron, primarily. the metal mostly consists of the pure element. Most cast iron also contains a few percent of carbon and some other impurities, but 95-98% of it is iron. ?So, the substances that make up an iron pot would be : Iron. Beside that, there will probably be alittle bit of carbon and some other impurities substance hope this helps New questions in Health. 1. The body is warm to the touch, yet the room is cool. . No rigor is present. What can you determine about time of death?Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and

Water is a pure substance, but it surely contains two kindsof atom: oxygen and hydrogen. Iron is an element as a result of it's composed of one more or less atom. Gizmo Warm-upAtoms are tiny particles of matter which can be made up of three debris: protons, neutrons, and electrons.

Read the whole lot about it here. Also know, what are the two parts that join in combination to provide water?

In the other hand, water is a compound- two or extra parts (in the case of water, hydrogen and oxygen atoms) chemically bonded in combination to make a brand new substance. If you burn hydrogen in air, two hydrogen atoms mix with one oxygen atom to make H2O.

Beside above, what is water made up of chemically? Water is a chemical compound and polar molecule, which is liquid at usual temperature and drive. It has the chemical components H2O, meaning that one molecule of water is composed of 2 hydrogen atoms and one oxygen atom. Water is found almost in every single place on earth and is required by means of all known existence.

Likewise, people ask, what is a water molecule fabricated from?

Everything is manufactured from atoms. An atom is the smallest particle of a component, like oxygen or hydrogen. Atoms sign up for in combination to shape molecules. A water molecule has 3 atoms: two hydrogen (H) atoms and one oxygen (O) atom.

Can a unmarried oxygen atom exist?

Oxygen can exist as atomic oxygen if no other oxygen atom is around. O2 has a lower energy level than 2 separated atoms of oxygen. Some people will explain it with then fact that oxygen has simplest 6 valence electrons and desires to have Eight electrons in its valence shell.
