The substitution reaction was successful but not fully effective. 19. If the data was inconclusive, then comparing various compounds and the unknown based on physical characteristics would be the first step, titrations would also be a good method. 20. To get a better yield, redoing the experiment would require careful attention in the recrystallization steps: amount of solvent used, how hot solvent is, if the mixture cools to room temperature before placing it in an ice
Mansa Musa could have taken a much shorter route and gone straight to Mecca, but instead went out of his way to take a longer route which passed through cities who only got gold through trade of salt. By doing this he could make more people want to come to Mecca to receive abundant, free gold without having to trade salt. Next, in Document C it explains that "Mansa Musa's hajj made the difficult trip north to Taghaza"(Document C). This shows that the hajj of Mansa Musa took a difficult trip to a city, which as explained by Ibn Battuta as "nothing but sand with a salt mine"(Document C). If this place was so bad, and all it had was salt and more salt, why would Mansa Musa take the time to go here?
Treat,mets included things like rest and fresh air. Rather than the usual things people like exorcists or traditional healers would do. (“Hippocrates and His Legacy.”) By Hippocrates using science to prove that diseases are a natural thing, he saved the lives of many and proved that not everything can be cured with magic or witchcraft and that sometimes we need nature and the logic of science to prove that something 's are natural and not supernatural. Thanks to Hippocrates, other societies have been heavily influenced by his work. By using it as inspiration, they have found new things in the field of medicine which have helped our society with many amazing advancements that have saved many lives.
This shows that while society was increasingly more progressive, women were still limited more than men in their rights and responsibilities. Cavendish was more outspoken about the inequalities between men and women because she was a philosopher and woman herself. Colbert, the French finance minister under Louis XIV, wrote that due to the increasing prosperity of the country, France “[established] several academies for both letters and sciences” (Doc 10). This shows how it became increasingly acceptable for people to study science. Colbert seems to support science because it is an indicator of a powerful and prosperous country.
One of the more famous pursuits of exoteric alchemy would be the desire to transmute lower metals (iron, copper, nickel, etc.) into higher, more valuable metals (silver and gold). While this has never been reliably or efficiently accomplished, it was something that many alchemists all over the world sought after and some even claimed to have attained. Typically in order to complete this task, a special object was required that granted the alchemist near supernatural powers: the philosopher's stone. This object has also been referred to as the elixir and may represent man’s complete knowledge, understanding, and master of the natural world.
Without Gutenberg’s printing press, books would not be as common as they are today. Additionally, da Vinci’s advancements in the anatomy of the human body allowed diseases to be treated more efficiently. The curiosity and inquiry of individuals years ago has continued to affect our lives today, based on their advancements in science and technology. Galileo’s discoveries from
If I was in this time, I would have went to California because of the chance. Although many were found out of luck, it would be a 50/50 chance in which I would be able to become a millionaire. Within the passage "A Rush To The West" in the part, "The California Gold Rush" it states, "They also looked in streams. This process, called placer mining, did not take much labor, money, or skill. Miners washed dirt from a stream in a pan, leaving grains of gold in the bottom.
Because Columbus had limited amounts of ships he could not take as many natives as he would have preferred and this could be an indication to why he wrote his letter the way he wrote it. Ultimately having the support of the crown worked in his favor to exploit the land and its people. Columbus’ discovery of this new land led to the Columbian Exchange where animals, plants, and humans were “products” of the New World and transported to the Old World. Another product he came across was gold something he seems to leave out of this document. The way Columbus took advantage of the native people was brutal not only by enslaving them but by colonialism which essentially is a takeover.
Students Name Teachers Name Course Date Birth Mark My reaction about the story is that the story’s final message is very good and it tells about many things that are not clearly good or bad. Nathaniel Hawthorne tells about the scientist Aylmer who is also a philosopher and that is why he always believes on his philosophy. So he uses his scientific research about the things he wants to have. Although he is a very good scientist and philosopher but he does not like his wife Georgiana the way she is. Author’s writing way of telling about Georgiana was very good, but he must have given something about her character as well.
Well first off, we use the same procedures and tools to predict earthquakes as volcanoes. That means all that money is being spent on two different predictions when it can be used for many other things like the military or to pay the dodea workers so we don’t have another government shutdown. The government needs to be more wise where they spend their money. Anyways, it is dumb for the government putting their money into volcanoes already but EARTHQUAKES! That is the meaning of the word dumb.
This supposed superiority to other imprisoned groups meant the often received better treatment. Many Witnesses became personal servants for Nazis, which was a much better option than other prisoners had. The effect this had on likelihood of death is evidenced by the fact that non-German Witnesses had a much higher death rate than German Witnesses. SS chief Hienrich Himmler had admiration for how strongly the Witnesses stuck by their faith. Himmler said SS men needed to have the same “Unshakeable faith” in Adolf Hitler.
I chose to use Cundiff’s work in my paper because his position on euthanasia was very insightful. He gave numerous examples that supported his argument very well. While reading his book I could sense that he did extensive research before writing it. His book has helped me in forming an argument against the use of active euthanasia and physician assisted suicide. David E. Cundiff is author, but he is also a doctor and an editor which gives him great credibility.
While it may not be fair to credit the Aztecs with the use of herbs as a point of superiority, since the biodiversity was much grander in the New World than in Spain, they without a doubt had a greater understanding of their importance in medicine. The Aztecs, under Moctezuma I, had implemented vast botanical gardens dedicated to experimenting with the usage of herbs for medicine, this can perhaps be viewed as one of the first instances of government supported scientific research. This was years before any kingdom in Europe had come up with the same idea. The creation of these gardens with the express intent of scientific research is noteworthy when compared to the Spanish Inquisition’s wholesale attack on medical
Gunpowder is one of the greatest breakthroughs, but whether it has helped or hurt the human race more is debatable. Guns allowed us to make hunting easier when it was essential to hunt to survive. On the other hand, gunpowder has also allowed the creation of huge weapons of mass destruction and has caused billions of deaths worldwide. On the other hand, men waged war before the invention of guns. So it can be said that guns were not the cause of all those deaths, they just made it easier to create destruction and death on a massive scale.
The purpose of this lab was to change pennies from copper to silver to gold, like alchemists have attempted to do in history. Through the data and observations gathered throughout this experiment, it can be concluded that the pennies were not changed into a different element. For example, the density of the penny from 2005; which was the penny that was experimented on to see whether or not it could turn into silver; was 4.62 g/cm3 before the experiment and 4.89 g/cm3 by the end of the experiment. If this copper penny really would have turned into silver, then the density of the penny would be 10.49 g/cm3; which is the density of silver; by the end of the experiment. The penny may have turned silver in color, but this was only because it was plated in the zinc that was added to the beaker of water in the experiment.
