What is the redox series of metals and redox pairs?
The redox series of metals is a list of metals arranged in order of their tendency to lose or gain electrons in a chemical reaction. This series helps predict the direction of redox reactions and the relative strength of reducing and oxidizing agents. Redox pairs, on the other hand, are a pair of substances involved in a redox reaction, where one substance is oxidized and the other is reduced. The redox pairs are essential in understanding the transfer of electrons between substances in a chemical reaction.
-
How can one recognize redox pairs in a redox reaction?
Redox pairs in a redox reaction can be recognized by identifying the species that undergo oxidation and reduction. The species that is oxidized is the reducing agent and the species that is reduced is the oxidizing agent. These two species form a redox pair. Additionally, redox pairs can be identified by looking for changes in oxidation states of the elements involved in the reaction. The species that increases in oxidation state is being oxidized and the species that decreases in oxidation state is being reduced, forming a redox pair.

What is redox chemistry?
Redox chemistry is a branch of chemistry that deals with the transfer of electrons between chemical species. The term "redox" is derived from the words "reduction" and "oxidation," which are two types of chemical reactions that involve the transfer of electrons. In a reduction reaction, a chemical species gains electrons, while in an oxidation reaction, a chemical species loses electrons. Redox chemistry is important in many natural processes, such as respiration and photosynthesis, as well as in industrial processes like metal extraction and corrosion.
-
What are redox couples?
Redox couples are pairs of two chemical species that are involved in a redox reaction. One species in the pair undergoes oxidation (loses electrons) while the other undergoes reduction (gains electrons). These couples are essential in maintaining the balance of electrons in chemical reactions. Examples of redox couples include Fe2+/Fe3+ and NADH/NAD+.

Novel Concepts for Iron- and Manganese-catalyzed Homogenous Redox Transformations
Transition metal catalysis plays a crucial role in the development of new chemical transformations, which can be broadly applied in organic synthesis, medicinal chemistry, synthesis of biologically relevant molecules, pharmaceuticals and other related fields.In recent years, the need for application of sustainable methods is significantly growing due to the necessity of waste-free transformations.Plenty of industrially run processes still apply classical procedures, which often lead to production of tons of waste as a consequence of multistep synthesis.Thus, development of novel catalytic systems which would afford complex molecular structures via straightforward processes is still desired.Hence, metal-catalyzed transformations play a crucial role in the development of new synthetic strategies, as they can easily lead to the reduction of synthetic steps and, ipso facto, reduction of waste leading to atom-economic transformations.Application of transition metals particularly in homogenous catalysis was initiated by industrial processes such as carbonylation of alkenes and alkynes by metal carbonyls, production of polyethylene and polypropylene by the Ziegler-Natta catalysts or conversion of ethylene into acetaldehyde in the Wacker’s process.This breakthrough inspired investigation of other synthetic reactions, which could be catalyzed by transition metals.Soon after, the field was dominated by application of catalysts containing precious-metal centers leading to the facile synthesis of higher molecules.Significant role of transition metals in chemistry was highlighted by Nobel prizes in 2001 (K.B. Sharpless, W. S. Knowles, R. Noyori) for metal-catalyzed enantioselective hydrogenation and oxidation reactions, in 2005 (R.Schrock, R. Grubbs, Y. Chauvin) for application of transition metals in metathesis and in 2010 (R.F. Heck, A. Suzuki, E. Negishi) for application of Pd-based systems in cross-coupling reactions, which with enormous impact modernized organic synthesis in research laboratories and in industry.However, the application of late and noble metal catalytic systems exhibits crucial drawbacks.Noble metals are expensive, due to their low abundance in the earth crust (Figure 1)[4] and related challenges in their extraction.Moreover, they are toxic and lead to formation of toxic waste. Taking into account the huge impact of catalysis nowadays and how it can influence our life and environment, modern chemical society focuses on finding more economically and environmentally friendly methods.As an alternative, implementation of base metal catalysis gained a lot of attention as it can lead to most cost-effective and more environmentally friendly protocols.Moreover, base metals can demonstrate similar reactivity as noble metals or exhibit new features, leading to other interesting transformations.

Digital Protest and Activism in Public Education : Reactions to Neoliberal Restructuring in Israel
Digital protest and activism in reaction to the consequences of neoliberalism in public education have become a global phenomenon in the second decade of the 21st century, emerging in countries such as the US, UK, France, and Israel.Teachers, parents, and other stakeholders in education are increasingly using digital media in their protest and activism efforts, yet these efforts have hardly been investigated to date.This book addresses this gap and employs an empirical exploration of the way in which Internet-based protest activity concerning public education issues is constructed, mobilised, and carried out.In doing so it provides key insights for the study of educational politics in the digital age.It shows how digital media is used by teachers and parents to create a bottom-up politics, spanning a common divide in the study of education politics between the macro (policymaking) and the micro (school) levels.The authors propose a novel taxonomy of uses of social media by digital activists, and argue that Internet-based social mobilisations develop different patterns of use of social media, based on the lived experience of their members and potential supporters.Finally, the book situates the rise of digital activism in education within the neoliberal restructuring of national education systems and the rise of neoliberal discourse of competition, budget discipline, and measurable achievements.The authors highlight three cases of Internet-based mobilisations in Israel, in which teachers and parents successfully affected public education policy. By providing a case-study driven analysis of digital protest and activism in education, this book will prove an invaluable text for researchers, leaders and practitioners in the field of education policy and comparative education.

What are redox reactions?
Redox reactions, short for reduction-oxidation reactions, are chemical reactions in which one substance loses electrons (oxidation) while another substance gains those electrons (reduction). This transfer of electrons between the reactants leads to changes in the oxidation states of the elements involved. Redox reactions are essential for various biological processes, such as cellular respiration and photosynthesis, as well as in industrial processes like metal extraction and corrosion.
-
What is the difference between a redox reaction and a non-redox reaction?
A redox reaction involves the transfer of electrons between reactants, resulting in changes in oxidation states of the elements involved. In contrast, a non-redox reaction does not involve the transfer of electrons between reactants and does not result in changes in oxidation states. Redox reactions are characterized by the presence of both oxidation and reduction half-reactions, while non-redox reactions do not have distinct oxidation and reduction components.
-
Are these redox reactions possible?
Yes, redox reactions are possible if there is a transfer of electrons between the reactants. In a redox reaction, one substance loses electrons (oxidation) while another gains electrons (reduction). This transfer of electrons results in a change in the oxidation states of the elements involved. If the reactants have the potential to undergo these electron transfers, then the redox reactions are possible.
-
Is this redox reaction correct?
Without knowing the specific redox reaction in question, it is difficult to determine if it is correct. However, in general, a redox reaction is correct if the oxidation numbers of the elements involved are balanced on both sides of the equation and if the total charge is conserved. Additionally, the number of atoms of each element should be the same on both sides of the equation. It is important to carefully balance the redox reaction to ensure that it accurately represents the transfer of electrons between the reactants and products.
