Fields in the Natural Science includes Biology, Chemistry, Mathematics, Physics, while Geography, Social Studies, history in the Social Science. The other general subjects are mandatory to both streams such as English, Physical Education and national and foreign language subjects. And it's scored out of 600 for both natural and social stream [5]
Electrochemical engineering is the branch of chemical engineering dealing with the technological applications of electrochemical phenomena, such as electrosynthesis of chemicals, electrowinning and refining of metals, flow batteries and fuel cells, surface modification by electrodeposition, electrochemical separations and corrosion.
English chemist John Daniell (left) and physicist Michael Faraday (right), both credited as founders of electrochemistry. Electrochemistry is the branch of physical chemistry concerned with the relationship between electrical potential difference and identifiable chemical change.
Potentiometry passively measures the potential of a solution between two electrodes, affecting the solution very little in the process. One electrode is called the reference electrode and has a constant potential, while the other one is an indicator electrode whose potential changes with the sample's composition.
In March 2022, Amhara Regional Government Education Bureau sent a team to the agency to request an explanation from the Ministry of Education about grading "errors" in the national examination. 20,000 complaints have been filed against the result of the grade 12 leaving examination, in which the government selects students to join 43 universities across the country.
He also introduced a powerful battery at the annual meeting of the British Association for the Advancement of Science in 1839. Grove's first cell consisted of zinc in diluted sulfuric acid and platinum in concentrated nitric acid, separated by a porous pot. The cell was able to generate about 12 amperes of current at about 1.8 volts. This cell ...
Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions. In electrogenerated chemiluminescence, electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light upon relaxation to a lower-level state.
A platinum cathode electrocatalyst's stability being measured by chemist Xiaoping Wang. An electrocatalyst is a catalyst that participates in electrochemical reactions. ...
