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

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

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

A chemical reaction is a process in which the identity of at least one substance changes. A chemical equation represents the total chemical change that occurs in a chemical reaction using symbols and chemical formulas for the substances involved. Reactants are the substances that are changed and products are the substances that are

own words‚ discuss the difference between adverse selection and moral hazard. Provide your own example for each problem. Adverse selection and moral hazard are both examples of market failure situation due to hidden information from the buyer or seller in a market. In adverse selection‚ hidden information is usually present before an agreement is made; where as‚ in moral hazard‚ hidden information is revealed after an agreement has been made. Adverse selection refers to a situation in which

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

Clinical Depression - is the most frequently encountered mental illness. Clinical depression is now considered a physical condition in which there is a fault in the brain chemistry. It may afflict up to 5% or more of the population. Symptoms of depression include a distinct change in mood accompanied with an extreme feeling of hopelessness. Other symptoms

endothermic reaction happened everywhere around us. Basically exothermic and endothermic reaction is transfer energy to the surroundings and take in energy from the surroundings (BBC GCSE bitesize). If the reaction forward ，then is exothermic.If the reaction is the backwards ‚then is endothermic. When a reaction take place‚ the energy started to transfer from different object to the surroundings or take away energy from the surroundings. When temperature started to change.

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test
