The Reactivity Series of Metals
="col">Reactivity and Reactions Potassium K Very reactive, very rapid with cold water forming the alkah potassium hydroxide and hydrogen gas (which is ignited). 2K + 2H 2 O (l) -------> 2KOH (aq) + H 2 (g) Sodium Na Fast reaction with cold water ..
Comparative Properties of Metals and Non-Metals
. Non-metal exhibit both electrovalency or covalency. Deposition during electrolysis They are always deposited at the cathode. They are always deposited at the anode. Redox reaction These lose electrons and hence get oxidized. These gain electrons and hence get reduced. Redox agents They ..
Solution
(called hydration energy) is released in the third step. This compensates the higher energy needed to remove electron in second step. The net effect is that it has greater tendency to lose electrons in solution than other alkali metals and the reaction: Therefore, lithium is the strongest..

. Thus for each U-235 atom the two Pu-239 atoms are produced. Thus in breeder reactors, the formation of fissionable nuclei is more in comparison to their respective consumption. Fissionable nuclides like U-235 or Pu-239 are also called fissile nuclides. On the other hand, non-fissionable nuclides ..
b) With Metals
Nitric acid behaves differently with different metals at different concentrations. i) With sodium, potassium and calcium the reaction is highly explosive. ii) With magnesium and manganese With magnesium and manganese, cold and extremely dilute (1%) nitric acid, rea..

Explained everything so well and did everything quickly.Amazing tutoring. My most favourite. Helped me a lot! :D
Good teaching skills, an amazing tutoring, would recommend it to everyone - Maadai
This tutor is very good. Tutor help you to understand the concept of the problem rather than just complete the problem.
Great sessions, learned a lot and got lots in and techniqul problem systm is showing me out of the session when i am not ,This is Awesome - Haley
