The advantages and disadvantages of chemical energy depend on the ways in which energy is stored and released during a chemical reaction. Chemical energy is the force that powers everything in the world, from the human body to vehicles on the road.Know More
According to Health Research Funding, chemical energy is defined as the energy stored within chemical bonds released through exothermic reactions. There are several energy sources that can be used to create a chemical reaction. These range from crude oil, coal, wood and other combustible material. One of the main advantages of using chemical energy is that it is the most abundant source of energy available. Chemical energy is also easily combustible, which makes it great for powering engines and vehicles.
The main disadvantage of chemical energy is that it has adverse effects on the environment. Burnt crude oil emits carbon dioxide into the atmosphere, which contributes to global warming. Chemical energy is also harmful to human health due to the pollution released as a byproduct of the chemical reactions. It is for this reason that scientists are looking for renewable energy sources that are more efficient and less harmful than chemical energy. Current alternatives to chemical energy include solar energy and wind energy.Learn more about Chemistry
The molecules of one reactant are combined with those of another reactant to form a new substance during a chemical reaction. As the chemical bonds are broken, the positions of electrons change, resulting in a product with properties that are different from the properties of the reactants. Various temperatures and catalysts are needed for different chemical reactions to occur.Full Answer >
An element or compound that enters into a chemical reaction is called a reagent, while the elements or compounds that result from a chemical reaction are called products. Reagents can be further defined as reactants, catalysts or solvents.Full Answer >
Respiration is a chemical reaction that can be expressed by the equation C6H12O6 plus 6O2 yields 6CO2 and 6H2O. This generally states that glucose and oxygen yield carbon dioxide and water. An aerobic reaction of this nature releases approximately 3,000 kilojoules per mole of material in the reaction.Full Answer >
There are a few telltale signs that can help indicate that a chemical reaction has taken place; these include the creation of one or more new substances and a noticeable energy change from the reaction site. However, telling whether a chemical reaction has actually taken place is not always very easy to observe.Full Answer >
