Chemical reactions have been occurring since the beginning of the world. However, the chemists came to know about them first in the 18th century; that is when they started to study and get their head around them. Processes like fermentation—wherein the sugar is converted into alcohol—have be...
What chemical reactions take place in photography? What happens when chlorine reacts with water? Which of an atom's electrons are involved in chemical reactions? What occurs when an atom loses an electron? Which chemicals change sea water's colour?

摘要: A study of the chemical changes in the composition of the plasma laser mixture which occurs during prolonged operation of a technological cue electron-beam-ionization CO/sub 2/ laser is reported. (AIP)关键词:engineering carbon dioxide lasers laser materials chemical reactions electron beams ...
ionic equations are chemical equations where electrolytes are depicted as dissociated ions. they are frequently employed to illustrate the displacement reactions in aqueous media. some ions participate in these processes, whereas others are not. spectator ions do not react and are generally left out ...
24 、Energy stored in fuel is chemical energy.───储存在燃料中的能量是化学能。 25 、The chemical must then be salted out and allowed to dry.───之后,这化学药品必须加盐分离,晾干。 26 、We need some liquid water, for all those chemical reactions to happen in, we need a source of ...
