3.3. Atomic H/C and O/C ratio The Atomic H/C and O/C for heavy oil obtained from different HDO solvent is presented in Fig. 2. Conversion and removal of unstable acid‚ aldehyde‚ sugar and water might reduce the O/C ratio. The atomic ratio was calculated by the value of water excluded heavy oil‚ since H/C ratio could also decrease‚ despite hydrogenation. Compared with that of bio-oil (0.9)‚ atomic O/C ratio was effectively reduced via HDO reaction (0.2-0.8)‚ H/C ratio reduced 1.0-2.0 (compared with

Phlogiston Theory According to the phlogiston theory‚ propounded in the 17th century‚ every combustible substance consisted of a hypothetical principle of fire known as phlogiston‚ which was liberated through burning‚ and a residue. The word phlogiston was first used early in the 18th century by the German chemist Georg Ernst Stahl. Stahl declared that the rusting of iron was also a form of burning in which phlogiston was freed and the metal reduced to an ash or calx. The theory was superseded

a display of unimaginable power in the form of an atomic bomb being deployed by the United States on Hiroshima‚ Japan. Innocent citizens heard an imaginable thunder‚ that was nothing short of earth-shattering. The decision to drop the atomic bomb on Hiroshima was not taken lightly. The Manhattan Project‚ a top-secret American scientific endeavor‚ worked tirelessly to develop a weapon of unprecedented power. The successful test of the first atomic bomb‚ codenamed "Trinity‚" on July 16‚ 1945‚ marked

what to do to deal with Japan was a tough one. America made the right decision on dropping the atomic bomb on Japan. The atomic bomb was necessary in order to assure the war would end as soon as possible. On August 6th the first atomic bomb was dropped on Hiroshima‚ on august 9th a second one was dropped on Nagasaki‚ and on August 10th Japan declared its intention to surrender. This is clear proof that atomic bomb was an effective way to end the war. Even if it did kill many people it might actually

Flame Tests Atomic Emission and Electron Energy Levels AES‚ or atomic emission spectroscopy‚ is a method which chemically analyzes the particular wavelength of a sample element to identify and determine the abundance of this certain element. The wavelength of the atomic spectral line unveils the identity of the element while the emitted light intensity is proportional to the number of atoms in the element. The flame test is also a very effective way to identify an individual element. The color

“Only after disaster can we be resurrected.“ The atomic bomb was a crucial And an enormous event in history. People’s actions can affect everyone; good or bad. Globally‚ the atom bomb affected everyone socially‚ economically‚ psychologically. To start with‚ it was the only nuclear attack in history and was known as “The Manhattan Project” because they were committed to speeding up the process in which They would build an atomic bomb. They dropped nuclear weapons on Japanese cities of Nagasaki and

then developed alternatives to end the war. These alternatives were to continue the conventional bombings‚ conduct a ground invasion‚ drop the atomic bomb‚ or conduct a demonstration of the atomic bomb to the Japanese (National Park Service‚ 2017). Once these alternatives were developed‚ the risks were analyzed. In the end‚ Truman decided to drop the atomic bomb. On the outside this may seem like a rational decision but the closer you look‚ the more you realize that this decision was skewed by bias

Had the Right to Drop the Atomic Bomb “On the morning of August 6‚ 1945‚ the American B-29 Enola Gay dropped an atomic bomb on the Japanese city of Hiroshima. Three days later another B-29‚ Bock’s Car‚ released one over Nagasaki. Both caused enormous casualties and physical destruction.” (Maddox 1). These disastrous events have weighted upon the American conscience ever since that day in history. Even though there are some people that disagree with the dropping of the atomic bomb‚ President Truman’s
