Melting pot

This experiment will allow us to determine the molar mass of the unknown solute through calculating the difference in freezing point of the pure solvent and the solution with the unknown solute. This lab will show case one of the colligative properties of a solution. This property is dependent upon the number of solute molecules or ions and not the identity or chemical property of the solute. A common example is water which both freezes and melts at 0°C no matter the amount of water or the size…

Salt is a solute, meaning it can dissolve in anything with solvent compounds such as water; it can also create a mixture when a solute and solvent are combined. Salt, rock salt in this case, is supposed to refrain the ice from forming on the roads. So instead of ice, it might be slush. In this project/experiment we will be determining if the mixture of water and salt will cause freezing point depression once frozen-or almost frozen.When it snows, people throw salt on the ground. The reason why…

Summary The study tested if EKG and core temperature would increase when you placed ice (down your back and in your hand) further from your body’s core. The outcome of the study was that your bodies EKG and core temperature decreased when placed further away from your body’s core. The significance of the study is that it shows people that if you place colder objects further from the core of your body, your vital signs are more likely to decrease, furthermore, the study presents an interesting…

color appeared in the reflux condenser, which is the visible liberation of nitrogen oxide gases. A total of 0.10 grams of purified benzil was produced from this reaction which contained a detected melting point of 82°C and a 34 % yield. This seemed to be approximately 10 degrees less than the ideal melting point of 94°C, which could be interpreted as deficiency of purity. The infrared spectroscopy, support this reasoning because shows a peak at 3316.65 cm-1, that appears to be a residues of…

Loung Ung, the author of Lucky Child, was a survivor of the Cambodian Genocide that happened during the period between 1975 and 1979, when more than two million Cambodians were killed by the Khmer Rouge, which counted as nearly 25% of the country’s total population (p. xi). Every aspect of life was monitored and controlled by the Khmer Rouge, who was aiming to clear all their political threats and to create a utopian state (p. xii). Most of the citizens, including Loung and her family members,…

First They Killed My Father Essay The book First They Killed My Father by Loung Ung takes place in Cambodia during the Cambodian Genocide. The Cambodian Genocide is the action of Pol Pot and the Khmer Rouge, who killed many people based on ethnicityt. The main character, Loung Ung, lives in Phnom Penh, the capital of Cambodia. On April 17, 1975, the Khmer Rouge takes over Phnom Penh forcing Loung and her family to flee the capital. Loung's three older siblings are forced to go work at different…

the Armenian Genocide was to slaughter an entire body of people whereas the Cambodian Genocide was meant to restart the country in a new “Year Zero.” The Cambodian Genocide was led by Pol Pot and the Khmer Rouge; while they did not simply want to rid Cambodia of all its people, the actions and ideas of Pol Pot and the Khmer Rouge led to a horrific ending. The goal of the Cambodian Genocide was to turn the country into a communist agrarian utopia (United to End Genocide.) The Khmer Rouge wanted…

Pol Pot: Beast of the Southeast Of all the cruel and horrendous tyrants history has bedeviled upon humanity, Pol Pot is among the most evil and unforgiving. It was under his rule that from 1975 to 1979, millions of innocent lives were snuffed out during an event known as the Cambodian Genocide. The Cambodian Genocide was an effort by the tyrannical government of Cambodia, known as the Khmer Rouge, to establish a perfect communist utopia. They planned to do this by disposing of anyone in the…

Cambodia’s seizure of power from the government of Lon Nol in 1975 and lasted until the Khmer Rouge was overthrown by the Vietnamese in 1978. North Vietnamese forces seized South Vietnam’s capital, Saigon, and by the Khmer Rouge and its leader, Pol Pot, in 1975.” Around 156,000 Cambodians died in the civil war, more than half being civilians. Like the Cambodian Genocide, a student from one of the Freedom Writers tells from their perspective about driving with their African American friends…

Don’t Think I’ve Forgotten:Cambodia’s Lost Rock n’ Roll by John Pirozzi was about Cambodian music, culture and art, and Cambodia’s tragic and disaster past under the Khmer Rouge regime. This movie illustrated how music is a soul of nation that shape Cambodian’s life and tradition itself. In addition, it also portrayed how music, artists and their way of life were affected during the war. There were a lot of interesting facts and details, likes and dislikes and why this movie grasp me in terms of…
