Chemical energy is that which is either released or absorbed when a chemical reaction takes place, such as the release of heat and electrical energy from a hydrogen fuel cell. Another example is the heat release derived from burning wood or other organic substances. Burning represents a commonly relied upon chemical reaction used to release the stored energy in a wide variety of biomass fuels ranging from coal and natural gas to oil and other fossil fuel derivatives.Know More
Chemical bonds store energy and the proper chemical reactions will release that stored energy for human use. Most of the stored energy comes from the sun through photosynthesis, a process of absorption and storing of solar energy in organic mass until it is released through burning. The exploitation of biomass fuel, however, does not come without drawbacks because burning them also produces byproducts which are harmful to the environment.
Burning biomass fuel has produced atmospheric carbon dioxide levels that are higher than what have occurred in 600,000 years. This has led scientists to seek out alternative forms of energy-releasing chemical reactions that can provide for human energy needs without the drawbacks of environmental pollution. Some of the new technologies being explored include the development of improved catalysts for splitting water into hydrogen and oxygen, more efficient battery components and methods that can release energy from biomass fuels through chemical reactions other than burning.Learn More
There are 20 amino acids that are active in the human body. In addition to these, there are approximately 250 non-protein-forming amino acids. There are three main types of amino acids that the body processes: essential, nonessential and semi-essential.Full Answer >
Calculate the pH value from the Ka by using the Ka to find the concentrations, or molarity, of the products and reactants when an acid or base is in an aqueous solution. Calculate the pH by taking the -log of the concentration of the H3O.Full Answer >
Inorganic compounds form ionic bonds, have high melting points and are made from either single elements or compounds that do not include carbon and hydrogen. In solutions, they break down into ions that conduct electricity. Organic compounds have a carbon-based structure with covalent bonding and are often volatile in nature. Even in liquid state, they do not conduct electricity unless they are salts formed with inorganic acids and bases.Full Answer >
Enzymes are organic molecular proteins composed of amino acids. At any point in time, when work is taking place within a cell, it is being accomplished by the enzymes. Their purpose is to facilitate swift chemical reactions that allow the cell to break things down or assemble things as necessary. These processes are what allow a cell to grow and reproduce.Full Answer >
