... These can be subdivided into the following principal methods; 1- Neutralization: The process in which a solution of one reactant, the titrant, is carefully added to a solution of another reactant, and the volume of titrant required for complete reaction is measured. i.e. these are based on reaction ...

... In the electrochemical series, the position of calcium is higher than that of sodium. The order is different from that in the reactivity series. This is because calcium atom loses electrons more readily in cell reactions than in reaction with air, water and dilute acids. ...

... The three classes are ionic, covalent, and metallic. Ionic carbides are formed by the most electropositive metals. These may contain the dicarbide(2 ) ion, C22 , or the true carbide ion C4 . Both types of ionic carbides react with water to produce the appropriate hydrocarbon. Covalent carbides are f ...

Solving Linear Congruences
... Let me summarize what I’ve just shown. I’ve proven that two solutions of the above form are equal mod m if and only if their parameter values are equal mod d. That is, if I let t range over a complete system m of residues mod d, then x0 + t ranges over all possible solutions mod m. To be very speci ...
