SELECTED REDOX REACTIONS RESULTS AND DISCUSSION Oxidation-Reduction reaction also known as redox reaction is a process in which there’s a net movement of electrons between reacting species. These types of reactions involve two separate elementary reactions: one that loses electrons and another that gains the electrons that was lost. Gaining of electrons is referred to as Reduction reaction (the species that undergoes reduction is called as oxidizing agent) while losing of electrons is called

ASSIGNMENT in DOMESTIC TOURISM and GEOGRAPHY *Rehabilitation of EDSA* *Reclamation of Manila Bay* Submitted by: NAEG‚ Nelian N. III-CTM Submitted to: Prof. Arnold Germina Reaction Paper Rehabilitation of EDSA: The rehabilitation of EDSA is one of the nicest ideas to ease the traffic in Metro Manila especially it is a major highway and almost everybody use it. In contrast to that‚ Pres. Aquino is right to suspend it and make further study about it. Surely‚ it will take time to

My Reaction Paper This is my reaction paper on a movie that I watched entitled “The Wizards Of Waverly Place: The Movie”. Wizards of Waverly Place: The Movie follows the Russo family as they embark on a vacation to the Caribbean resort where Jerry and Theresa first met. Alex‚ upset that she was forced to accompany her family on the trip‚ conjures a spell that erases her parents’ fateful first meeting and puts the Russo family’s very existence in peril. In order to reverse the spell‚ Alex

association of molecules of a solvent with molecules or ions of a solute. As ions dissolve in a solvent they spread out and become surrounded by solvent molecules. Example: As an ionic compound dissolves‚ such as NaCl‚ the ions become surrounded by the solvent‚ say H2O(water) molecules. The ions are said to be ’solvated’ as they become surrounded by the solvent‚ similar to a hoard of bees surrounding a nest. The solvation process helps stabilize the ions in solution and prevents cations and anions from
