The combat record of the Winged Hussars stands for itself. In 1577 a massive charge of this ultra-heavy cavalry unit smashed a German army from Danzig, blitzing into the teeth of a 12,000 man force and crushing them until all that remained was a well-trampled patch of red where the enemy army once used to be.
Dichloromethane is an organic compound with the formula CH2Cl2. This colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. Although it is not miscible with water, it is miscible with many organic solvents.
A chlorofluorocarbon (CFC) is an organic compound that contains only carbon, chlorine, and fluorine, produced as a volatile derivative of methane, ethane, and propane.They are also commonly known by the DuPont brand name Freon.The most common representative is dichlorodifluoromethane (R-12 or Freon-12).s in simpler alkanes, carbon in the CFCs and the HCFCs is tetrahedral. Because the fluorine and chlorine atoms differ greatly in size and effective charge from hydrogen and from each other, the methane-derived CFCs deviate from perfect tetrahedral symmetry.
