The ignition mixture in “alumina thermite” process consists of a mixture of:(A) Magnesium powder and BaO2 or KClO3. ... Hint: The alumina thermite process uses a metal powder and a metal oxide, heating them to ignition where they undergo a highly exothermic, oxidation-reduction reaction. ...

In such instances, the ignition occurs without the presence of an external ignition source: It is solely attributable to the self-heating process of the material. It is not to be confused with the term autoignition (see next Subsection). The spontaneous ignition process is due to either ...
Under double catalysis of heating and MnO2, persulfate anions could fastly combine with MnO2 with formation of metastable [Mn(IV)-O-O-SO3]II, then rapidly decompose to sulfate radicals, and then desorb in form of sulfate anions [17]. Higher PDS concentration provided more precursors for this...

Alkenes are electron rich species due to the presence of C=C bond which can behave as a weak nucleophile. Answer and Explanation: Out of the options given, only alkenes can readily react with a solution of Potassium permanganate according to the rea...
3.8.4.2.1Aqueous potassium permanganate oxidations Oxidative cleavage is a procedure often employed to degrade large compounds or to introduce different functionality into complex molecules. A number of reagents have been used for this purpose with generally good success.1–4 ...
the extent of crystallinity, was ascertained via Raman Spectroscopy, and stability of material was observed through Thermo gravimetric analyses (TGA) by using a thermo-gravimetric analyzer (Perkin Elmer Pyris 1, Champaign, IL, USA). The temperature was increased from 20 to 500 °C at a heating...
