Periodicity of Chemical Properties 4. Which element is a commonly found element which forms a green gas in its elemental state? This gas is extremely toxic and can be fatal at concentrations of less than 1000 ppm. This element forms an interesting allotrope called Buckminster fullerene. Which clement is Ruckminster fullerene composed of and how did this allotrope get its name? 6. Many gemstones are composed of aluminum compounds. When this element is present in trace amounts in beryl or...

In a certain chemical processing plant a liquid chemical element is used in a manufacturing process Said chemical element is stored in three different tanks. A level sensor in each tank generates a voltage at HIGH level when the level of liquid in the tank falls below 25%. Design the complete circuit to monitor the level of the chemical element that lights an alarm when the level of at least two tanks drops below 25%. Implement the solution using the...

Name and write the chemical formula for 3 toxic organic compounds and classify them accordingly. Briefly explain what they are used for in society. Include at least one that is not pesticides, Methoxychlor,Hexachlorobenzene,Toxaphenes,Cyclopentadienes,Endrin,Aldrin,Dieldrin,Heptachlor,Chlordane,Dechlorane (these are used in the lesson) Note that a chemical formula refers to a specific chemical or compound, a substance with molecules that are all the same (unless they are isomers, don't worry about that). For example, "PCBs" or "dioxins" are small classes of compounds - each...

The toxic, highly unstable element derium (chemical symbol De) is discovered and is found to have a body-centered cubic unit cell. The radius of a derium atom is 86.906pm and the density of solid derium is 133.8g/cm3 at 25.0°C. a) Calculate the length (in pm) of an edge of the bcc unit cell for derium. 1) b) Calculate the molar mass (in g/mol) of derium. c) As for any cubic unit cell, part of the derium unit cell is empty...

(15 points): Phosgene (COC2) is a highly toxic gas that was used as a chemical warfare agent in World War l. Although it is now banned for that purpose by international agreement, phosgene is still produced for industrial uses (where it must be handled very carefully!) It forms at high temperatures from a mixture of carbon monoxide and chlorine gases: 2. CoB)+ Cl2(8)COCI2(8) Kc 4.95 at 600. K If 7.5 atm worth of each reactant are pumped into a 5.00x103...
