Coupled Reactions ABSTRACT A way to drive a non-spontaneous reaction forward is by coupling it with another reaction that is highly spontaneous‚ resulting to a spontaneous overall reaction. In this study‚ since the extraction of C(s) from CO2(s) is a non-spontaneous process‚ it was coupled with the oxide formation reaction of Mg‚ a reaction with high spontaneity‚ so that the process of the extraction of C(s) would proceed. The reactions and products which were a mix of black and white

experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color will get

My beliefs on the meaning of life in religion and interpretation of such things.<br><br>In approaching the question of ’the meaning of life’ we have to examine the nature of meaning itself. Meaning‚ is by definition the point‚ or the intended goal. Consider the point of humans and the universe as seen from monotheistic religion. If life and the universe is some sort of toy or form of entertainment for some greater being‚ his point‚ his own entertainment‚ would then be the meaning of humans and the

A light-emitting diode (LED) is a semiconductor light source.[6] LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Appearing as practical electronic components in 1962‚[7] early LEDs emitted low-intensity red light‚ but modern versions are available across the visible‚ ultraviolet‚ and infrared wavelengths‚ with very high brightness. When a light-emitting diode is switched on‚ electrons are able to recombine with holes within the device‚ releasing energy

The government has been trying to address the “big issue” of obesity for the past decade‚ and suggests that Britain is bursting as its seams. Referring to the size of its people I assume and not the British flood defences being breached. Another year and I’ve been introduced to yet another anti-obesity campaign. However obesity has been a problem for many years and is still increasing‚ so one must think that the numerous anti-obesity campaigns aren’t being effective‚ I mean surely it’s not as if

Martin Gottfried’s portrayal of American drivers in "Rambos of the Road" is only partially accurate (Gottfried‚ 2005‚ p.474-476). I have had experiences with both considerate motorists as well as aggressive motorists. This article looks at the angry drivers without even considering the more passive ones. In Gottfried’s conclusion he states‚ "It seems to me that it is a new America we see on the road now. It has the mentality of a hoodlum and the backbone of a coward" (Gottfried‚ 2005‚ p.476). Though

------------------------------------------------- ABSTRACT ------------------------------------------------- The copper reaction experiment was demonstrated by adding the reagents like 16M HNO3‚ Distilled water‚ 6M NaOH‚ 6M H2SO4‚ Acetone‚ Zinc metal and Methanol into the beaker with the copper wire. The experiment was also demonstrated to observe how copper reacts while different reagents were being added. It was also demonstrated to practice the common laboratory techniques such as methods
