Carbon-13

the common elements is Carbon (C). Carbon is essential for life and other important areas of the world. Carbon is a non-metal, that is in a solid state at room temperature. There are many different unique properties that help Carbon do what it needs to do. Carbon is the sixth most abundant element on Earth, and used in the daily lives as oil or coal. The origin of the name is Latin, coming from the word Carbo. Carbon was date discovered is not known specifically but has been known since ancient times.…

Diagram 1 ¶: The diagram of the atom Carbon-12 represents an ion and an isotope. Carbon-12 has six protons and six neutrons in its nucleus, as shown on the diagram. Outside of the nucleus, this atom has five electrons. The protons are shown in the color orange, neutrons are in the color blue, and electrons in the color teal. The scientific principle subatomic particles says they are smaller than the atom itself, meaning protons with a positive charge, neutrons with a neutral charge, and…

In conclusion, we reported the synthesis of fused and isolated triazoles based on thieno[2,3-d]pyrimidines. The synthesized 1,2,4-triazolo compounds were screened for their anticancer activity at a concentration of 10 μΜ against a panel of 60 cell lines derived from nine different types of cancers, and also screened for their PDE 5 inhibitory activity. The possibility of combining 1,2,4-triazolo moiety to thieno[2,3-d]pyrimidines should open new opportunities for the rational design of…

In the IR spectrum, RM-10-1i, peaks that are present correspond to the functional groups in 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone. These functional groups are sp2 hybridized carbons at 3031 cm-1, sp3 hybridized carbons at 2981 cm-1, a carbonyl at 1735 cm-1, aromatic carbon-carbon stretching at 1660 cm-1, an ester carbon-oxygen stretching at 1144 cm-1, and alkene carbon-hydrogen stretching at 698 cm-1. There was no alcohol present in this spectra, indication that all of the catalyst was…

Why is Apollo 13 Considered a Successful Failure? "Houston, we've had a problem..." Apollo 13 was to land on the moon. An explosion on Apollo 13 forced it to have to circle the moon without landing. Around five and a half minutes after Apollo 13 took off, John Swigert, Fred Haise and James Lovell felt a vibration. Then the center engine shut down. This caused the remaining four engines to burn longer than what they had planned. The S-IVB third stage had to burn longer to put Apollo 13 into…

Success is the accomplishment of an aim or purpose. The purpose of Apollo 13 was to land on the moon and return safely. Granted Apollo 13 did not land on the moon due to an oxygen tank exploding, they returned the astronauts home safely, which should be the biggest goal or accomplishment. Apollo 13 was a success after it returned in one piece. A failure is the lack of success. To fully succeed the crew needed to touch down on the moon, and return home. After having technical difficulties,…

Directed by Ron Howard, the movie Apollo 13 recounts a mission, following the moon landing, where everything went wrong. Tom Hanks starred as Jim Lovell, the commander of the Apollo 13. Bill Paxton plays Fred Haise, the lunar module pilot. Kevin Bacon played Jack Swigert, the third member of the crew who was originally on the backup crew. Jack Swigert got moved up thanks to Ken Mattingly, played Gary Sinise, predicted to get the measles. This movie takes place in 1970, close to a year after…

Apollo 13, also known as (AS-508), was suppose to be the third mission to land on the moon. The crew on the spacecraft consisted of Fred W. Haise, Jr., lunar Module Pilot, John J. Swigert, Jr., command module pilot, and James A. Lovell, Jr., commander. Launched at 2:13 p.m. on April 11, 1970 from the launched from complex 39A at Kennedy Space Center. The Apollo 13 mission was planned to launched and land on the moon and return back to Earth. Unfortunately, after about 56 hours into their…

spewed its precious cargo out into the void. With all oxygen depleted, the last fuel cell flickered out. The crew of spaceflight Apollo 13 was left stranded with no power, no oxygen, and no way to return--205,000 miles from home. Immediately, Houston sprang into a frenzy of action. It was clear that entirely new solutions needed to be rapidly found, tested, and executed if the astronauts were to survive. The most pressing problem was power. The command module was running on backup power, but it…

To go far and beyond as past Apollo missions were the plans for the Apollo 13 mission, but with a sudden change of plans they only had one mission left, get back home safe and alive. They launched on April 11, 1970, orbiting around the moon and back to earth for five days, twenty-two hours, fifty-four minutes, and forty-one seconds, and landed back to Earth in the Pacific Ocean on April 17 1970. On the mission, the crew composed of James A. Lovell Jr. as commander, Charles M. Duke Jr. as Lunar…
