  • sulfur dioxide

    sulfur dioxide also sulphur dioxide in british english is the chemical compound with the formula s o 2.it is a toxic gas responsible for the smell of burnt matches.it is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of fossil fuels contaminated with sulfur compounds.

  • iodine

    iodine is the fourth halogen, being a member of group 17 in the periodic table, below fluorine, chlorine, and bromine; it is the heaviest stable member of its group the scarce and fugitive fifth halogen, the radioactive astatine, is not well-studied due to its expense and inaccessibility in large quantities, but appears to show various unusual properties due to relativistic effects .

  • gunpowder

    gunpowder, also known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. it consists of a mixture of sulfur s , charcoal c , and potassium nitrate saltpeter, kno 3 . the sulfur and charcoal act as fuels while the saltpeter is an oxidizer.

  • lead

    lead ii oxide gives a mixed oxide on further oxidation, pb 3 o 4. it is described as lead ii,iv oxide, or structurally 2pbo·pbo 2, and is the best-known mixed valence lead compound. lead dioxide is a strong oxidizing agent, capable of oxidizing hydrochloric acid to chlorine gas.

  • lead paint

    lead paint or lead-based paint is paint containing lead.as pigment, lead ii chromate pb cr o 4, 'chrome yellow' , lead ii,iv oxide, pb 3 o 4, 'red lead' , and lead ii carbonate pb c o 3, 'white lead' are the most common forms. lead is added to paint to accelerate drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion.

  • crystal

    a crystal or crystalline solid is a solid material whose constituents such as atoms, molecules, or ions are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. in addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.

  • phosphorus

    phosphorus is a chemical element with the symbol p and atomic number 15. elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on earth.it has a concentration in the earth's crust of about one gram per kilogram compare copper at about 0.06 grams .

  • copper toxicity
