Rate of Reaction
The rate of a reaction is the speed at which a chemical reaction happens. If a reaction has a low rate, that means the molecules combine at a slower speed than a reaction with a high rate. Some reactions take hundreds, maybe even thousands, of years while others can happen in less than one second. If you want to think of a very slow reaction, think about how long it takes plants and ancient fish to become fossils (carbonization). The rate of reaction also depends on the type of molecules that are combining. If there are low concentrations of an essential element or compound, the reaction will be slower.
There is another big idea for rates of reaction called collision...

Energy keeps all living organisms alive, as they need a continual supply of energy to function in order to survive. Some of these processes are continuous such as, metabolism, which is the chemical reactions which occur in the body, these occur by using or releasing energy from chemical substances. Another continuous process which use energy is the transporting of molecules in order for them to break down, and to build new ones. The breakdown of large molecules into their simpler forms to release energy is known as catabolism, for example, when glucose is used in a cell to release energy. And the opposite reaction, is called anabolism. This is when energy is used to build complex structures...

Corrosion is an unavoidable problem that occurs almost everywhere. It can happen when a solid interacts with its environment. Corrosion oxidises metals back to some natural ore. Despite not all corrosion is unwanted, corrosion has become a growing economic concern. Taking an example of what happens in USA, corrosion of metals costs the economy almost $300 billion per year at current prices, which translates to 3-4% of GDP. Besides the economic concern, corrosion may adversely affect the environment. Worse than all those mentioned, corrosion can cause unexpected death from corrosion-related accidents. For example, the sudden collapse caused by corrosion fatigue of the Silver Bridge over the...

What is Stress? Webster defines: It a physical, chemical, or emotional factor that causes’s bodily or mental tension and may be a factor in disease causation. Stress is also feeling that’s created when we react to a particular event. It something we are not aware of, and sometime cannot control. Some would define stress as our reaction to the ups and downs of everyday life. Others might define stress as worry, pressure, tension, etc. Stress is defined as the non-specific response of the body to any demand placed on it, by Dr. Hans Seyle. In other words, anything that causes a "change or a reaction" in your body is called stress.

Ozone layer is a deep layer in the stratosphere, encircling the earth that has large amounts of ozone in it. Ozone is a colourless gas found in the upper atmosphere of the earth that is formed when oxygen molecules absorbs ultraviolet, and undergo a chemical reaction known as photo dissociation or photolysis.
In this process, a single molecule of oxygen breaks down into two oxygen atoms.The free oxygen atom[o],then combines with an oxygen molecule and forms a molecule of ozone.The ozone molecule in turn absorbs ultraviolet rays between 310-200nn[nanometer] wavelength and thereby prevent these harmful...

Fuel cell principle:
Discovered in 1839 by an English physicist, Sir William Grove, the fuel cell principle relies on the simple fact that water could be split into hydrogen and oxygen by sending an electric current through it, a process which is called electrolysis. Therefore, by reversing the procedure you could produce electricity and water. He created a primitive fuel cell and called it a “gas voltaic battery”. After experimenting with his new invention, Grove proved his hypothesis. Fifty years later, scientists Ludwig Mond and Charles Langer invented the term “fuel cell” when they attempted to build a practical model to produce electricity.[i]
A fuel cell is an...

The Earth system consists of the geosphere, atmosphere, hydrosphere and biosphere, and can be regarded as a large-scale example of Le Chatelier's Principle where systemic perturbations are mitigated through complex feedbacks to eventually establish an amended equilibrium. The geosphere impacts the other spheres as it regulates uniformitarianism through volcanism, while also providing the physical interface between the lithosphere and organic subaerial constituents of the earth system in the form of regolith; thereby facilitating biotic subsistence and terrestrial feedback. Considering spatiotemporal impacts of volcanism are inherently interconnected concerning volcanism, a temporal scale...

Yeast is a one-celled, microscopic organism, which is part of the fungi kingdom. Yeasts do not make up a single group (Smith & Smith, 2012). Yeasts use organic material as a means of making energy, which make them chemoorganotrophs (Smith & Smith, 2012). Carbon is procured primarily from hexose sugars, such as fructose and glucose. Yeast need either oxygen for aerobic cellular respiration or for species that are anaerobic, but also have aerobic methods creating energy (Smith & Smith, 2012). There are no species of yeast species that are known to grow only anaerobically. Yeasts thrive in an environment with a slightly acidic...

Gender is a psychological term that refers to the awareness and reaction to the biological term of sex. It also is a term that can construe more than one meaning. Gender is determined by biological, psychological, and sociological factors. Gender consists of three elements: gender role, gender identity, and sexual orientation or preference (Kenyon,...
