26‚ 2010 Experiment No. 2 – Coupled Reactions R.S. Velasco Institute of Chemistry‚ College of Science University of the Philippines‚ Diliman Quezon City‚ Philippines Received Dec. 1‚ 2010 ------------------------------------------------- ------------------------------------------------- ABSTRACT The reaction of carbon dioxide gas to form carbon monoxide and oxygen gas is non-spontaneous (∆G > 0)‚ thus we coupled it with the reaction that has a free energy that is negative

Reminder: These notes are meant to supplement‚ not replace the laboratory manual. SN1 Reaction Notes Background and Application Substitution Nucleophilic First Order (SN1) reactions are one of the most common type of organic reactions. SN1 reactions can be used to make a wide variety of new compounds. In this experiment‚ t-amyl alcohol will be converted by a SN1 mechanism to 2-chloro-2-methylbutane. Safety Precautions Concentrated Hydrochloric Acid is 12M. It will cause visible destruction

Ignition systems are well known in the field of internal combustion engines such as those used in petrol (gasoline) engines used to power the majority of motor vehicles‚ but they are also used in many other applications such as in oil-fired and gas-fired boilers‚ rocket engines and so on.

Conservation Lab Report Purpose: The purpose of the lab was to see how the total mass of the products of a chemical reaction contrast to the total mass of the reactants Hypothesis: The hypothesis for both experiment which involved iron( III ) Nitrate and sodium hydroxide for the first experiment and antacid tablet in water was that the mass would increase by a small amount since during the reaction the product will gain additional energy and mass. Apparatus and Materials: Eye protection test tube two

Ball mill is mainly composed of a barrel body‚ lining plate‚ gear and other main components. Mill liners are of high wear resistance and also the replacement of mill liner of ball mill is very important. Because of the working condition and strength requirements of ball mill‚ the routine maintenance is very important. Repair for ball mill is a regular work. Repair work will have a direct impact on energy saving ball mill operation rate and life span. In order to detect the defects and eliminate

Recall the consideration from the philosophy of religion involving replacement of the unregenerate person with a “different person altogether” (cite‚ pp. 139). Does it follow that Jeremias experience a replacement of personal identity with a different person altogether? Epistemically speaking‚ it would seem that Jeremias did not survive a change‚ because although he is aware of the idea ‘homosexuality is immoral and therefore not entitled to having a status equal to heterosexuality’‚ yet rather than

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
