ABSTRACT The common ion effect involves how the solubility of a salt changes when some ion that is common to both added substance and the salt in question is introduced. The presence of a common ion hinders the ionization of a weak acid or a weak base hence this is known as the common ion effect. Simply put‚ the effect

In the bottle rocket lab‚ our rocket was able to achieve lift off after filling it with water and compressed air. We estimated that our rocket went thirteen and one half meters into the air for an awesome six seconds. When we launched our rocket‚ it followed a parabolic arch from the launch pad to the landing area. As our rocket was flying through the air‚ it maintained its stability through the air due to the fins that were on the side of the rocket which helped to push the air in an even streamlined

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 air molecules
