Which methods of producing electricity require chemical reactions?
Nuclear. The rest are mechanical.
Which part of an atom plays a major role in chemical reactions?
Chemical reactions are a result of valence electron transfer and/or sharing. Valence electrons are located in the outer-most orbitals of the reactant elements. In a sense, though, you could say protons are also involved in chemical reactions. Although an element will never donate, accept, or share protons in a CHEMICAL reaction, they are part of the determination in an elements reactivity. Reactions that do involve protons are termed "nuclear reactions," and are not chemical reactions…
What effects do alternative methods of producing electricity have on the environment?
There are various effects on the environment: hydro-electric dams flood large patches of river, often removing fertile land and even towns and villages. They may alter the spawning habitat for fish. tidal barrages may affect fish movements, and may cause a silt buildup. wind farms are producing complaints from neighbours for their background noise. all alternative, that is, renewable methods of producing electricity mean that less carbon dioxide is put into the atmosphere from the…
What is unit process?
Unit process includes all the treatment methods in which the removal of contaminants is brought about by chemical or biological reactions. it is considered as a secondary treatment . while Unit Operation involves only the methods in which physical forces predominates. it is considered as primary treatment.
What are some renewable and non-renewable methods of producing electricity?
Renewable methods would be to use technology such as solar panels, dams, wind turbines and others to generate electricity from renewable resources such as the water and the Sun. Non-renewable methods would be to burn fossil fuels such as coal. However, renewable sources of energy are definitely much better as the run forever and there is no need to burn it, which produces greenhouse gases such as carbon dioxide.
What are contribution of chemistry to food production?
- all additives for foods are chemical products - cooking involve chemical reactions - preservation of foods involve frequently chemical procedures - agrochemistry is an important branch of chemistry - pesticides are chemical products - fertilizers are chemical products - industrial production of many foods including drinks are chemical processes - all foods are analyzed by analytical chemistry methods
What scientist studies chemical reactions?
Analytical chemistry is the analysis of material samples to gain an understanding of their chemical composition and structure. Analytical chemistry incorporates standardized experimental methods in chemistry. These methods may be used in all subdisciplines of chemistry, excluding purely theoretical chemistry. Biochemistry is the study of the chemicals, chemical reactions and chemical interactions that take place in living organisms. Biochemistry and organic chemistry are closely related, as in medicinal chemistry or neurochemistry. Biochemistry is also associated…
What are the Steps in generating electricity?
There are several methods used to generate electricity. However, the processes usually used to create electricity on a large scale are one of the following: To use the potential energy of water, moving water is made to move a generator. Otherwise, water is heated in different ways - by burning coal, or with nuclear reactions. In this case, the water evaporates, the pressure tends to expand, and moves the generator.
What are the methods of producing emf?
Presently, there are six known methods for producing a voltage or electromotive force (emf). Some of these methods are more widely used than others, and some are used mostly for specific applications. Following is a list of the six known methods of producing a voltage. 1. FRICTION - Voltage produced by rubbing certain materials together. 2. PRESSURE (piezoelectricity) - Voltage produced by squeezing crystals of certain substances. 3. HEAT (thermoelectricity) - Voltage produced by heating…
