Laboratory Write-Up
The game in which we participated simulates the early efforts of scientists because they had very little to work with. They too had to guess the size and shape of the atom. In 1911, Rutherford conducted a series of experiments in which he bombarded a piece of gold foil with positively charged alpha particles emitted by radioactive material. Most of the particles passed through the foil undisturbed, suggesting that the foil was made up mostly of empty space rather than of a sheet of solid atoms. Some alpha particles, however, "bounced back," indicating the presence of solid matter. Atomic particles, Rutherford's work showed, consisted primarily of empty space surrounding a well-defined central core called a nucleus. The game portrays the marbles as the alpha beams that bounce off the foam cores. The foam cores represent the nucleus, and the empty space shows how little space the nucleus actually takes up. The game we played can be different than what Rutherford experimented with is because the nucleus is much smaller than actually in the game. The foam wasn’t even in proportion with the size of the space used for the game.
Early, atomic scientists actually did not have the opportunity of just peeking under the board to see the shape. They had to go with the results that they had. That’s why it was so important for them to be precise because if they did anything wrong then this would invalidate their research. They needed to be real precise because they were not as fortunate as scientists today who have technology to back them up. Scientists today do not necessarily have the opportunity to just peak under the board to obtain results.
¨Father forgive us for living (Shakur, 1). Tupac speaks from the african american point of view, as in a world where african americans are discriminated, simply living is a crime In ¨Untitled 1,¨ by Tupac Shakur, the theme is how African Americans have been discriminated by other races and even self-discriminated and how that needs to be changed. Tupac examines the struggles of African Americans, and talks about how they have been discriminated for a very long time and how it has caused sorrow. That being said, he remains hopeful towards the future, and wants to inspire children to spark change.
It was able to make him aware of the injustice around him. It allowed him the tools to detest the system of slavery, which without, his story would not be atypical. White slave owners understood that with education the black man would not take an inch, but an ell. This is exactly what Douglass did, utilizing this resource to unclasp the grip of slavery and spread his knowledge. Literacy inherently in the beginning of its story with Douglass, was scattered into pieces. He configured these pieces into his understanding of a weapon his masters detested. Douglass through comprehension unsheathed the manifestation of literacy, but found it sharp enough to cut even himself. Ultimately smelting his weapon, he harnessed its full potential, reforming his tool into a key. This key was able to open the door to Douglas’s life beyond even the long unraveling whip of suffrage. Frederick Douglass through his story used knowledge, as
In "Energy Story" uses an explanation of atoms and tells us the parts of an atom and its structure. In the text it
Through all his family and education issues, he standup himself to become a well-known hip-hop artist according to his history background. From all his released a couple albums and then was offered to be some movies. He make some songs and music videos with them that made it big on the Billboard charts. For example, in this movies and albums called, “Power respect Juice” (1992), “Bullet”(1996), “Gang Related” (1997), “ all eyez on me”(1996),”Greatest Hits”(1998), and “Until the end of time”(2001), according to all these released, he won prizes from music and artist industry, people can recognized him. Tupac was became rich and famous and he is not showing off his own style. This showed that this is him and who he really is. People following his beliefs because he treated people equally and judged people equally. This is a big difference from him and other hip-hop artists. He has a lot of self-values that people are influenced about
In the same fashion that Elvis defined Rock ‘n’ Roll; Tupac Shakur defined the hip-hop music scene, as we know it today. What made Tupac (also known as 2Pac, or Makaveli) so special were his enormous talent, his on screen friendly looks, and the sense that he was “real” and talked the talk, while walking the walk. Tupac was born on June 16, 1971, Tupac Amaru Shakur. He was named after Tupac Amaru, the Inca Indian that was sentenced to death by the Spaniards. He was originally from Brooklyn, New York. Tupac spent a lot of time moving around as he was growing up. He was the son of a Black Panther activist Afeni Shakur and Billy Garland. Tupac moved from Harlem, to Baltimore, to Oakland. The constant moving caused Tupac to fit into his new communities by joining gangs, and his lengthy rap sheet was created even before his profalic entry into music and film. He was arrested eight times before even turning twenty (MTV.com).
This experiment's purpose is to calculate small values (molecular and atomic size) in different phases, such as a gas, liquid, and solid by using practical methods. If the molar mass is known, one can estimate the atomic size through practical measuring techniques with little experimental error. This experiment consists of measuring a block of a solid element (Copper and Zinc), measuring the volume of the lead pellets, and measuring the amount of carbon dioxide gas in a balloon. These experiments will allow one to estimate the atomic or molecular size by using doable measurements and calculations.
Tupac Shakur (2pac) was known as one of those rappers that has made a difference in the black community during the 90’s. All his music talked about the reality of black lives and the struggle of being black not only for black men but also for black women. His songs gave hope to African Americans, and to help them see that black was/is beautiful. Even though Tupac has many hit songs and albums, Keep Ya Head Up has been one of the best songs that Tupac has ever recorded! “The blacker the berry the sweeter the juice the darker the flesh the deeper the roots”.
Determining the Relative Atomic Mass of Lithium An experiment has been carried out to determine the relative atomic mass of Lithium by using two different types of methods The first method that was carried out was to determine the volume of Hydrogen produced. In this experiment a fixed amount of Lithium was used, in my case it was 0.11g. At the end of this experiment, the volume of Hydrogen gas I collected was 185cm³. Then using the solution of lithium hydroxide made from experiment one, I used it in the titrating experiment, to find out the total volume of Hydrochloric acid used to titrate the lithium hydroxide. RESULTS TABLE Experiment Initial Volume ( cm³) Final Volume ( cm³) Total volume Of HCl used ( cm³) Rough 0.2 30.3 30.1 1 6.3 35.8 29.5 2 2.7 32.0 29.3 Average 29.6 CONCLUSION Method 1 [IMAGE]2Li (s) + 2H20(l) LiOH(aq) + H2(g) Number of moles of Hydrogen. Volume of hydrogen gas was 185 cm³. Weight of Lithium was 0.11g. N = __V__ _185_ = 0.0077 MOLES 24000 24000 Number of moles of Lithium.
The Meaning of the Word "Mass" The word Mass comes from the words ‘Ist Missa Est’ which is Latin and
Rap artist tell their life story through rap. Not only do they tell their story, but they also have a moral to their story. Tupac was one of the greatest rappers of all time. He was murdered at the age of 25. He is still, even in death, one of the most influential artists in the lives of urban people. Tupac told his life, from the beginning to the end, in his music. He was in a gang, he did drugs, and he was also known as a “thug.” If peop...
In the essay “Learning to Read and Write,” Frederick Douglass illustrates how he successfully overcome the tremendous difficulties to become literate. He also explains the injustice between slavers and slaveholders. Douglass believes that education is the key to freedom for slavers. Similarly, many of us regard education as the path to achieve a career from a job.
That is not the only hardships he faced; in fact his mom was in jail while she was pregnant with him. He was originally named Lesane Parish Crooks. Later his mother had his name changed to Tupac Amaru Shakur which means shining serpent ("Tupac Shakur." Bio.com. 1). His mind was shaped by his mother 's twisted ideas, while also being exposed to her struggle with drug abuse. Which can obviously be seen took impacted him later on in
An atom, by definition, is the smallest part of any substance. The atom has three main components that make it up: protons, neutrons, and electrons. The protons and neutrons are within the nucleus in the center of the atom. The electrons revolve around the nucleus in many orbitals. These orbitals consist of many different shapes, including circular, spiral, and many others. Protons are positively charged and electrons are negatively charged. Protons and electrons both have charge of equal magnitude (i.e. 1.602x10-19 coulombs). Neutrons have a neutral charge, and they, along with protons, are the majority of mass in an atom. Electron mass, though, is negligible. When an atom has a neutral charge, it is stable.
Tupac Amaru Shakur was an African-American rapper, poet, and record producer during the 1990’s. In his adolescent years, he attended the Baltimore School for the Arts where he took acting and dance classes, like ballet. He was taught radical politics by his mother, which helped him develop ideas about topics he would later use in his many works. At an early age, Tupac had seen the injustices of the real world. His mother was a former Black Panther activist who turned to substance abuse during Tupac’s childhood. Aside from that, he and his mother also moved many times while they lived together in New York City. While Tupac was in Baltimore, he discovered rap; not long after, he and his mother moved to the West Coast where he joined the rap group
The Atomic Theory began in roughly 400BC with Democritus in Ancient Greece and is universally believed to be correct today. Democritus who was born in 460 BC and died 370 BC and is known as the father of modern science. Democritus proclaimed that everything is made up of atoms. He continued his theory to say that atoms will always be in motion, between atoms there is empty space, atoms are unbreakable, there are an infinite number of atoms all different sizes and shapes. He also said that iron atoms are solid and strong and have hooks to lock them together, water atoms are smooth and slippery, salt atoms have sharp jagged edges because of its taste and air atoms are light and spiralling.
