Melting

The objective of this experiment was to identify an unknown sample by preforming classification tests such as: Bisulfite test, Schiff’s test, and Idoform test. Also, to confirm the identity of the unknown by melting point, IR spectroscopy, and 1H NMR. For the solubility test, 1 mL of deionized water was placed in a test tube. A few drops of the of the unknown was added to the test tube and mixed with a pipette. After a few minutes, the unknown was determined to be insoluble. Next, the Schiff’s…

accumulation is the amount of measured snowfall, the same is true in geology but they see it as accumulated snowfall annually on a glacier. The total amount of of ice that glacier looses annually is called ablation and it takes into account the aspects of melting, sublimation, iceberg calving…

A situation when I compared three samples is when I was trying to figure out what method of melting ice would work the best. During the winter it gets very icy and slippery on my driveway and walkways. I knew that something had to be done, because the last time my mother visited she slipped and fell and hurt her arm. I was on a mission to figure out what would be the best method to melt the ice. I was not sure what would be the best method to melt the ice quickly, so I have decided to test and…

The guiding question is that which changes are examples of a chemical change and which are examples of a physical change? Our claim is that 100ml water mixed with salt paraffin wax melting are examples of physical change. While magnesium strip heated, sodium hydroxide and copper chloride mixed and hydrochloric acid added to sodium bicarbonate are chemical change. For task 1, we measure 100ml of water, weigh 5g of table salt and mix the 5g of salt and 100ml of water. Stir until change is seen.…

The United States of America is a melting pot of many different cultures, races, and ethnicities. The US has always retained its diversity in its citizens and simply having diversity is one of the factors that the United States prides itself in. According to information from the Census Bureau of the United States of America, as of 2015, there are approximately 321,418,820 people residing in this country. Of those 3 hundred-million plus people, there are more than five races among them all.…

for being beneficial for nations that are divided ethnically, racially, or ideologically. (enfranchise) Canada is established as a nation for being a melting pot, allowing the population to keep their own individuality. Their division in the power through their government is favored for parliamentarianism because of their nation being a melting pot. Race, ethnicity, and geography all make up Canada’s culture. The culture of Canada is dependent on these factors, and these factors are what…

effects of emissions, and pollution are killing the earth. One of the scares I remember reading about was focused on the icebergs melting and raising the sea level. People were raising awareness that the ice was melting off little by little each year and if they continued the world would be submerged under water due to global warming. Is it true that the ice is melting? Undoubtedly, but will they melt off enough to flood the earth by no means, in the book of Genesis God makes a promise with the…

CONTENTS RESEARCH QUESTION How does the length of carbon chains, specifically those related to alkanols, namely ethanol 1- propanol and 1- butanol, affect the heat of combustion? AIM To investigate how the length of carbon chains affect the heat of combustion and enthalpy, in order to determine which fuel would be the safest and most efficient to take on a camping trip. HYPOTHESIS If the number of carbon atoms in an alkanol is increased, then the alkanol containing the longest carbon…

Assimilation vs. Pluralism When observing how cultural groups come together as well as how they react with each other, two concepts can be used to understand how these groups will meld. These two concepts are assimilation and pluralism. While they are mostly contrary processes, they are not necessary exclusive to each other. These two process may occur at the same time within the same nations. Some groups may experience assimilation, while the other experience pluralism. Both process are were…

This burning is creating what is called the greenhouse effect. This is where gases cause the earth’s temperature to rise melting the ice on Earth. I agree with this information. There are hundreds of thousands of cars on the road. The majority produce fumes and carbon dioxide from their exhausts. These gases go up into the atmosphere creating the greenhouse effect which is…
