For the generation of electricity‚ the increase in electric vehicles will also increase the production of electricity from thermal and nuclear power plants‚ impact on the environment will be negative. The main positive impact of electric cars is friendly to the environment. However‚ a lower cost of electricity generation like nuclear power plants may have an opposite idea to electric car. Therefore‚ we can solve the problem by developing the electric vehicle and the renewable energy at the

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

metals arranged in order of their reactivity based on displacement reactions‚ reduction of their oxides by hydrogen or carbon‚ the relative ease of decomposition of their compounds and reactions with oxygen‚ dilute acids and water. The higher up a metal is in the reactivity series‚ the more reactive it is. In the experiment conducted‚ the three metals‚ magnesium‚ zinc and copper each had to undergo displacement reactions and reactions with water‚ oxygen and dilute acids‚ to arrange them in the order

6/25/2014 Philosophy 201 Reaction to Kant Kant Kant first draws close to differentiating between a moral choice and a prudent choice. A prudent choice is a choice used in good judgment and is rational. Kant has no interest in morality being rational. A law is a law and thou shall obey it. The moral law is absolute. Thou shall not lie‚ means exactly what it says‚ thou shall not lie. No ifs‚ ands or buts about it. There is no reason why a person should lie because it is our duty as moral

Coralde Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion A combustion reaction is a reaction that liberates heat and light. Magnesium is a stable element and reacts violently with evolution of much heat and light. The reason the magnesium burned in carbon dioxide was because it combined with the oxygen in the CO2 leaving elemental carbon behind. CO2(g) C(S) + O2(g)

Each and every one of us has their own reaction about the third State of the Nation Address of President Benigno “NoyNoy” Aquino III. There’s always a negative and positive reaction. We always have comments in every part of the SONA especially the topics and issues that the president have mentioned‚ even the language that the president used. Most of the issues in our country were mentioned by PNoy like the billions wasted by PAGCOR for coffee. I agreed with what PNoy said‚ wondering if the people

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
