forming a continuous series of holes

Standard Deviation for continuous series - In this series too deviations may be taken either from the actual mean or from standard mean. The calculations will be simplified if the deviation are taken from assumed me..

. Hydrocarbons and their major sub groups form a homologous series of organic compounds. As an illustrative example, the simplest of all hydrocarbons is methane whose molecular formula is CH 4 . This molecule consists of a single carbon atom linked to four hydrogen atoms by sing..

Silver salt method is used for determining the molecular masses of carboxylic acids. This method is based on the fact that they form insoluble silver salts, which upon heating decompose to leave a residue of metallic silve..

Alkenes undergo hydration (addition of water across C=C bond) in the presence of dilute H 2 SO 4 to produce alcohols. The alkyl hydrogen sulphate is formed which on hydrolysis with hot water gives alcoho..

Alkanes, alkenes, alkynes, alcohols, aldehydes, carboxylic acids etc. form separate homologous series..

A series of the form a + (a + d)r + (a + 2d)r 2 + ... is called an Arithmetic-Geometric series. In the series if we put d = 0 we get GP and if we put r = 1, we get an A..

Radioactive Decay Series - The emission of a or b - particles from a radioactive element results in the function of new element called daughter element. If the daughter element still has unstable nucleus, it further disintegrates by emitting a or b - particle and produces a new daughter e..

Characteristics of Electrochemical Series - 1) Reactive metals are placed on top (e.g., Li) and they have a great tendency to get oxidized. Non-reactive metals like Ag and Au. 2) Any metal above hydrogen can displace it from dilute acids. Example: Any metal which is above another can disp..

Electrochemical Series of Metals - Different metals get ionised at different rates. For e.g., metals like sodium when exposed to air combine almost instantly with the oxygen present therein (sodium atom gives up an electron almost as soon as it is in contact with oxygen). On the other han..
