Why is hydrogen important as a future clean energy source? A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air). ...
All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportion of oxygen atoms. Although the st...
"Of 118 elements, the last thing I read was that 97% of our body's weight is just four elements," Steven Townsend, an organic chemist at Vanderbilt University, told Live Science. Those four elements areoxygen, carbon, hydrogen and nitrogen. So what, exactly, do these elements do?
A substance which cannot be decomposed into different kinds of matter by any means at present employed; as, the elements of water are oxygen and hydrogen. Element One of the ultimate parts which are variously combined in anything; as, letters are the elements of written language; hence, also...
Understanding Elements of DNA DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). It ...
Contrary to the lyrics of a popular ‘90s song that charted at No.1 for 15 (!) weeks,hydrogenis all around you. Being one of the key elements of water (H2O - with hydrogen present in duplicate), accessing this plentiful element is far easier than trying to drill for oil. ...
A chemistry major explores the complex ways the elements on the periodic table combine. Those elements can produce table salt, a combination of sodium and chloride, water, a combination of hydrogen and oxygen, and myriad other, more complicated compounds. In classroom- and laboratory-based coursewo...
Hydrogen is the simplest chemical element, or type of atom. It consists of just one proton and one electron. It is also the most abundant element, making up around 75% of the known matter in the universe. Vast amounts of hydrogen exist in water and living things. ...
