To describe the transfer of electron for both the aluminium and iron in the reaction: 2 A l ( s ) + F e 2 O 3 ( s ) → 2 F e ( s ) + A l 2 O 3 ( s ) . Concept Introduction: The most common driving forces which create product in chemical reactions are as follows: Formation of a solid. Formation of water. Transfer of electrons. Formation of gas. Oxidation-reduction reaction is known as redox reaction. In these types of reaction one reactant is oxidized and another is reduced. Oxidation: Oxidation is a process in which either 1 or all following changes occurs: Gaining of oxygen atoms. Increasing oxidation number. Loss of hydrogen atom. Loss of electrons. Reduction: Reduction is a process in which either 1 or all following changes occurs: Loss of oxygen atoms. Decreasing oxidation number. Gaining of hydrogen atom. Gaining of electrons.

Potentially Useful Information Spectrochemical Series: | < Br < SCN¯ < Cl° < NO3¯ < F° < OH° < C2O4²¯ ~ H2O < NCS° < NH3 < en < PPH3 く A student has three test tubes containing a metal (M) nitrate solution M(NO3)2 (aq) (where "M" represents a generic transition metal). The student adds aqueous ammonia (NH3) to one test tube, aqueous hydrochloric acid (HCI) to the second tube, and nothing more to the third tube, but forgets to label the tubes. After this, one test tube contains a red solution, one an orange solution, and one a yellow solution. Note: This metal, M, would follow the same rules that we used for Cu(II), Ni(II), and Co(II). The Jahn-Teller Effect does not apply. Complete each statement or answer each question below about the solutions in the three test tubes. The aqua complex causes less splitting of the d orbitals of the metal than the... ammonia complex. O chloro complex.
