I read the article “Tattoo Ink”. This reading had many chemical similarities to the type of things that we are learning about in class. A solid liquid is suspended into a liquid carrier, which could include various elements in the ink. This can be classified as a mixture, which we are learning about in class. When the needle hits the skin, the ink expands in your body to help create the image. When it expands, you are able to see the different mixtures because they show different colors. This shows a form of separation, which we are also learning about in class.

Crude oil is a thick, dark brown substance that can be found in the Earth’s crust. Crude oil is made up of various hydrocarbons. In order to separate the hydrocarbons, they must use distillation. All of the different hydrocarbons have different boiling points, which allows them to separate with heat. If one of the hydrocarbons has a low vaporizing point, it will evaporate to the top of the beaker, cool, and condense. The lower the boiling point, the lower it will evaporate in the beaker. Asphalt, diesel fuel, gasoline, kerosene, and many other resources can be used by the distillation of crude oil.

Jack,

Good posts. Looks like you understand the material. 5 stars x 2. MW

A kilogram is a metric measurement used for mass. This article is all about the first unit that we are doing in Honors Chemistry. It is about units of measurement, and what they are used for. There is a kilogram standard that had become defected, about 50 micrograms to light, and what would a standard be if it weren’t exact? The BIPM is making a decision on whether to redefine the kilogram, a decision that is going to be made in 2011. This relates to our class because in Unit One, we are using things like kilograms, micrograms, ect. to weigh various objects. We are also using different units such as meters, liters, and seconds.

Jack, Looks good. 5 stars. MW

In the year of 1504, Chinese scientists and astronomers recorded a "guest star". This guest star was seen in the Taurus constellation, or the Bull. The star was brighter than any other star in the sky, it progressively became brighter as the days went on. We now know that this was an explosion, or a supernova. When the explosion occurred, the star released chemicals into space. This is where we got the first 26 elements on the Periodic Table. The elements travel in space, and eventually will end up on planets like Earth. This article has many relations in what we are doing in class. We are learning about the elements in the Periodic Table, and this article shows how the first 26 were formed (helium, carbon, iron, manganese, ect.). Also, the article discusses chemical bonds in the element, which we are discussing in class as well.

Jack, Well obviously the stuff from that star didn't make our earth but it maybe will make planets many years from now. Good thoughts. 5 stars! MW

The sun is a mass of incandescent gas, a giant molecular furnace!

Do you know what a "molearchy" is? It has been scientifically proven that a molearchy is a type of government in which moles are in complete control; under this government Mole Day is celebrated three times a year and chemistry is the only scientific subject taught in school. Also, are you aware of what Avagadro ate in the summer? Watermolens. Alright, enough with the dibble dabble. Time for some history. I thought that it was interesting that Avagadro received no recognition for his discoveries during his lifetime. Just two years after he died, Stanislao Cannizzaro showed the use of his theory with impressive experimental results. I'd be pretty bummed if I was not recognized for making one of the biggest scientific discoveries...EVER. But, Avagadro di not do it all on his own. He based his work on the findings of Joseph Gay-Lussac, who discovered that all the gases when subjected to an equal rise in temperature expand by the same amount. I also found it interesting that Avagadro's favorite type of music was "Rock n' Mole".

Jack, Good piece of writing. Very funny! 5 moletastic stars. MW

I read the article about exploding dust. This has many relations to some of our experiments that we do in class. The dust does not need much to be set off, so much as static can trigger the explosion. When the first explosion ignites, the dust from other parts of the factory is disturbed and mixes with the oxygen in the air and causes an even larger explosion. I feel that this relates to our chemistry class because we are working with many explosions, and all of them need something to ignite the reactant. In this situation, the dust mixed with the oxygen is the reactant, and the previous explosion ignites it. Also the dust and the oxygen is a heterogeneous mixture because the cloud can be seen through, that is a characteristic of a heterogeneous mixture.

Jack, Right it's like a chain reaction - pretty scary if you think about it. 5 cloudy stars! MW

Because of my super genius intelligence, I already knew a couple of things about helium filled balloons. I knew that helium is the gas that can change the pitch of your voice, and also that a helium filled balloon will shrink faster than a air filled balloon. I also knew that sulfur hexaflouride gas would make your voice lower. To both your and my surprise, there were some facts that I had yet to know before reading the article. For example, I didn't know that the gasping reflex is set off by a build up of carbon dioxide gas in your bloodstream. Also, I didn't know that impurities in the tank of helium can cause serious injury or even death if you breathe it in. Another thing that I found surprising was the fact that a balloon filled with sulfur hexaflouride will increase in size instead of decrease.

Jack, Good job. I hope your super genius intelligence got even more super! 5 helios. MW

FIRST OF ALL, LETS POINT OUT THE THINGS I ALREADY KNEW ABOUT THIS ARTICLE. I DID HAVE THE COMMON KNOWLEDGE ABOUT HOW MOTION DETECTORS ARE USED. THEY ARE USED TO DETECT MOTION, AND THEY ARE ALSO USED AS A SECURITY SYSTEM. ALSO, I KNEW THAT THERE ARE MANY DIFFERENT TYPES OF MOTION DETECTORS. ANOTHER THING THAT HAS ALREADY BEEN BROUGHT TO MY ATTENTION IS THE FACT THAT A GERMAN PHYSICIST NAMED HEINRICH HERTZ. I WILL SADLY ADMIT... THERE WERE A COUPLE NEW THINGS THAT I LEARNED BY READING THIS ARTICLE. FOR EXAMPLE, I DIDNT KNOW THAT SOME MOTION DETECTORS USE A LIGHT SOURCE AIMED AT A PHOTO SENSOR. ALSO, I DID NOT KNOW THAT HIGH-FREQUENCY WAVES SHOULD BE ABLE TO EJECT ELECTRONS. FINALLY, I HAD NO IDEA THAT ALBERT EINSTEIN WON THE NOBEL PEACE AWARD IN 1921. AHHHHHHHH!!!!!!!!!!! (NOW I'M YELLING)

JACK!!!! STOP YELLING! btw Albert Einstein did not win the Noble Peace prize. He won the Noble prize in Physics! 4.9999999 stars.
