Redox reactions (Redox terminology‚ galvanic cells‚ standard electrode potentials‚ strength of oxidizing/reducing agents‚ corrosion and protection against it) Oxidation is defined as the loss of electrons and reduction is defined as the gain of electrons. Oxidizing agents‚ such as oxygen are defined as substances which accept electrons; reducing agents are substances which donate electrons. Redox reactions are: a) The reactions of metals with non-metals 2Na+Cl2→2Na+Cl- b) The reactions

Kate Steele 10-4-13 Per. 6 The Plague DBQ 1995 Beginning in the mid-fourteenth century‚ a plague swept the world like no other. It struck in a series of waves that continued into the eighteenth century. The first wave was estimated to have killed twenty-five million people‚ about a third of the Western Europe population at that time. Throughout the different outbreaks‚ the plague‚ also known as the Bubonic Plague or the Black Death‚ caused people to react in several ways. Some people believed

REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

1850s DBQ Between 1850 and 1861‚ underlying issues and events brought about discord and tension in the United States. These issues revolved around the radically different views on morality‚ from the North’s views to the South’s. The tensions stemmed from views and understandings of the Constitution’s purpose and uses being in opposition to the viewpoint of the other territory. The tensions caused by the differing beliefs were slowly built up since the American Revolution. Slavery‚ being an established

REACTION PAPER on GOD IS DEAD The lines‚ “God is dead. God remains dead. And we have killed him‚” can be true in literal sense. Subjectively‚ the lines presented are very agnostic and atheistic. Those are against my will and belief as a Roman Catholic faithful. The three shorter mentioned lines are three important points to be clarified about. The first line says‚ God is dead is true in literal sense. In the Scriptures‚ it written that Jesus became man and so he died as a human. Yes‚ I believe

Redox Reactions Reactions involving oxidation and reduction processes are very important in our everyday world. They make batteries work and cause metals to corrode (or help to prevent their corrosion). They enable us to obtain heat by burning fuels--in factories and in our bodies. Many redox reactions are complex. However‚ combustion and synthesis (from elements) are two ordinary examples which require very little description. Just a little more involved are the displacement reactions‚ with

Chemical Reactions Chemical reactions happen in almost everything around us. Reactions are very important in everyday life‚ and science. Chemical reactions are the changing of substances to other substances by the breaking of bonds in reactants and the formation of new bonds in products. There are different types of chemical reactions such as combination reaction‚ decomposition reaction‚ single-replacement reaction‚ double-replacement reaction‚ and combustion reaction. Combination
