Chemistry in Photography Background A photograph is an image made by a photo-chemical reaction which records the impression of light on a surface coated with silver atoms. The reaction is possible due to the light-sensitive properties of silver halide crystals. Equation form for silver halides: Ag + + e - Ag Species produced include: Ag2+‚ Ag2o‚ Ag3+‚ Ag3o‚ Ag4+‚ Ag4o In 1556‚ the alchemist Fabricius was the first to discover that light can photochemically react with these crystals to

SHAMINMENISHA How Water Rockets Work A water rocket works using the same principles as other rockets. There are three main forces in action: thrust (Fapp)‚ drag (Ffr) and weight (w=mg). The water‚ which is forced out by the difference between internal and atmospheric pressure‚ is a reaction mass that provides the thrust. All rockets have a reaction mass‚ which can vary from hot gasses that are expelled when a fuel is burnt (in the Space Shuttle’s SRB’s for example) to water in a water rocket. The
