Karen Mae L. Fernan February 01‚ 2013 BS Chemistry 3 Homework 6A 1. Assume that diesel fuel is C14H30 and that gasoline is octane. a. Calculate the amount of energy (heat) – in kcal - each releases per gram when combusted. b. Compare each as fuel for trucks. c. Why do so many large trucks have diesel engines? Gasoline: C8H18 C8H18 (l) + 252O2 (g) 8CO2 (g) + 9H2O (g) Standard Bond energies: H-C | 99 kcal/mol | C-C | 83 kcal/mol | O=O | 119 kcal/mol

nuclear warfare age and gave the world an idea of what radiation can do to your body if it is used in the wrong ways. Before the attack on Japan‚ the United States learned of new developments in science that could change the age of modern warfare. The uranium atom was a major factor in the development of atomic bomb when German physicists learned it was possible to split them in half to produce bombs

GENERAL AND ENVIRONMENTAL IMPACTS OF NUCLEAR BOMBS According to the movie‚ TRINITY AND BEYOND: THE ATOMIC BOMB MOVIE‚ on July the sixteenth year 1945‚ at a site called "Trinity"‚ a plutonium bomb ’ was piled and taken up the top of a tower. This plutonium bomb ’ was exploded thereby generating a very high measure of flash light and a fireball that radiated through 0.6 kilometers (0.37 miles) in 2 seconds. The detonative energy or power was equivalent to 18.6 kilotons of TNT. This fume grew up

Tehran. The work centered on a five megawatt research reactor supplied by the United States‚ which began operation in 1967 (Etemad‚ 1987). Iranian scientists and engineers also conducted research on the nuclear fuel cycle‚ the exploration of uranium mining and ore processing‚ and designed plans for a new nuclear research center at Isfahan (Etemad‚ 1987). By the mid-1970s‚ according to Etemad‚ Iran’s nuclear energy program had expanded‚ with the goal of producing roughly 23‚000 megawatts of electrical

vegetation were all contaminated‚ and ultimately‚ millions of human lives were also affected. The smelting process in Kabwe was unregulated when it was a hotspot for coal mines‚ so the concentration of lead in the soil and water today is a reminder of the mining era in Kabwe. The wildlife in Zambia is very unique‚ you can find hippos‚ rhinos‚ elephants‚ lions and many more different type of animals only found in savannas. One example of a food web in the savanna is the acacia tree‚ which is a primary producer

NUCLEAR ENERGY AND SAFETY Consumption of energy is increasing nowadays so nuclear energy has very importance for energy needs. Nuclear energy is produced naturally and in man-made operations under human control and it is a thriving global industry. A total of 435 nuclear power plants are operating around the world in 30 countries. Also ‚ nuclear energy has some advantages Nuclear energy has the lowest impact than fossil fuel energy on environment because nuclear plants don ’t emit

Almost every country stood by and watched as the bombs made by the simple process of fission of two atomic particles produced enough power to destroy

1. War in Iraq – effecting the oil crisis: Nowadays the war in Iraq has been effecting the oil price in a negative way. Because of the war‚ the oil price has risen dramatically. When the war just started (2003-2004)‚ an oil bar was $24‚- a barrel. It went up to $143‚- in 2011 and nowadays the price fell down to $122‚80 which is still almost 5 times the price it was before the war. The rise of the oil price has been a disaster for all the people around the world because the benzene/gas prices
