Lettris

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.

boggle

Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !

Look up fulminate in Wiktionary, the free dictionary.

Fulminates are chemical compounds which include the fulminate anion. The fulminate anion is a pseudohalic anion, acting like a halogen with its charge and reactivity. Due to the instability of the anion, they are friction-sensitive explosives. The best known is mercury fulminate which has been used as a primary explosive in detonators. Fulminates can be formed from metals, like silver and mercury, dissolved in nitric acid and reacted with alcohol. The chemical formula for the fulminate anion is O-N+C-. It is largely the presence of the weak single nitrogen-oxygen bond which leads to its instability. Nitrogen very easily forms a stable triple bond to another nitrogen atom, forming gaseous nitrogen.

Historical notes

Fulminates were discovered by Edward Charles Howard in 1800.[1][2][3]. Their use in firearms in a fulminating powder was first demonstrated by a Scottish minister, A. J. Forsyth, in 1807. Joshua Shaw then made the transition to their use in metallic encapsulations, to form a percussion cap, but did not patent his invention until 1822.

In the 1820's the organic chemists Justus Liebig discovered silver fulminate (Ag-CNO) and Friedrich Wöhler discovered silver cyanate (Ag-NCO). The fact that these substances have the same chemical composition led to an acrid dispute, which was not resolved until Jöns Jakob Berzelius came up with the concept of isomers[4].

Compounds

  • Silver fulminate
  • Mercury(II) fulminate
  • Fulminic acid
  • Cyanate - has related OCN- structure
