The chromium acts as a chemical fixing agent in the CCA. Although it has little to no preserving properties, it helps to bind other chemicals through chemical complexes to the wood's first few layers of living, structured cells. ]]> 2016-11-07 16:17:21 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/135829147 midorilenyard https://padlet.com/midorilenyard/o31v4711vsqv/wish/136452314         Arsenic poisoning is caused my high levels of arsenic in the body. Small amounts of arsenic are found in soil, water and air. Due to the amount of arsenic in all these very abundant places plants take it up when they are growing, therefore arsenic is also found in our food. The main source of arsenic poisoning is from food or drinking water. Some effects that long-term exposure to high levels of arsenic are  higher rates of skin cancer, bladder cancer, heart disease and can play a role in the development of diabeates, vascular cancer, and heart disease. In the western world the use of arsenic is rare, but in some places of the world, arsenic is still a popular pesticide, like in Asia.

Arsenic compounds have been known since the times of Ancient Greece and Rome. During that time the main use of arsenic was in the form of arsenic sulfide. The first people to recognize arsenic were alchemists, who were trying to find ways to turn  iron, copper, and others metals into gold in pursuit of eternal life. The way that Albertus Mangus discovered arsenic was by heating a vey common compound of arsenic , orpiment(As2S3), with soap. The result of this experiment was an almost pure form of arsenic.]]> 2016-11-12 20:23:09 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/137153344 midorilenyard https://padlet.com/midorilenyard/o31v4711vsqv/wish/137239418 2016-11-13 23:45:35 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/137239418 midorilenyard https://padlet.com/midorilenyard/o31v4711vsqv/wish/137241622      Arsenic by itself is a very, very dangerous substance it is even deadly. it was given the name "the silent killer" because it won't leave any evidence if you were to kill someone with it. Arsenic is in places like water, rice, soil and is used to feed livestock, but over exposure to arsenic is unsafe and can lead to forms of cancer and death. A very simple form of arsenic was developed during WWII and was a colorless, odorless, gas ,but was not used due to its high flammability. Although arsine was not used during WWII it was the base of other chemical gases that were soon weaponizied. One more great danger that arsenic can cause to your body is black foot disease. Black foot disease was an epidemic during the early 20th centuries. it was confined to the southwestern coast of Twain  and peaked during 1956 to 1960.]]> 2016-11-14 00:17:08 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/137241622 midorilenyard https://padlet.com/midorilenyard/o31v4711vsqv/wish/137243317 2016-11-14 00:37:37 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/137243317 midorilenyard https://padlet.com/midorilenyard/o31v4711vsqv/wish/137261825 Arsenic is very important for many different reasons. ne reason that arsenic is important is because we, as humans, use it to prevent unwanted critters from wandering into our homes. Another reason that arsenic is important is because we have been using and depending on it for centuries. Although arsenic is important for many positive reasons, a negative reason that arsenic is important is due to arsenic poisoning. ]]> 2016-11-14 03:59:12 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/137261825 midorilenyard https://padlet.com/midorilenyard/o31v4711vsqv/wish/137263405 The group of the pirncetogen includes nitrogen, phosphorus, arsenic, antimony, bismuth, ununpentium.  What makes all of these elements alike is the ability to form stable compounds, due to their likelihood to form double and triple covalent bonds. All these elements are also solids at room temperature, except for nitrogen(which is a gas at room tempature).]]> 2016-11-14 04:16:48 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/137263405 midorilenyard https://padlet.com/midorilenyard/o31v4711vsqv/wish/137265299 2016-11-14 04:38:03 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/137265299 midorilenyard https://padlet.com/midorilenyard/o31v4711vsqv/wish/137266496 2016-11-14 04:56:03 UTC https://padlet.com/midorilenyard/o31v4711vsqv/wish/137266496
