water
1) Describe the structure of water and indicate how this structure is responsible for many of the unique properties of this vital compound. Water is a vital compound which possesses many unique properties, based primarily on the structure of the molecule. In order to understand the principles behind water's properties, one must first understand the basic formation of water from its elements as a compound (a group of two or more elements). Water is comprised of two elements: Oxygen and Hydrogen. These two elements bond to form the compound H20. The molecule arranges itself in the bent shape (Fig 1), with a 104.5 degree angle, which allows for the molecule to become polar. The singular oxygen atom becomes slightly negative, and the two hydrogen atoms become slightly positive. This polarity allows for dipole-dipole interactions, or the attraction between the positive and negative end of a water molecule to another water molecule. It is now possible for one to apply this knowledge of a water molecule's structure to its properties. The properties of water include such things as a high surface tension, a low vapor pressure, a high specific heat capacity, a high heat of vaporization, and a high boiling poi
(How is this interpreted through collision theory?) There are many factors that contribute to a reaction's rate, but two of the primary ones are concentration of reactant and particle size. Particles lacking the necessary kinetic energy to react bounce apart when they collide. It must be noted that this graph shows the net change of the reaction mechanism, (a reaction with a various number of elementary reactions). This means that there are unfavorable interactions between the water and the object's surface, consequently making it difficult to wet the surface of the needle. Hydrogen bonding is what defines water's boiling point. Whether an object sinks or floats depends on its properties. Take for instance the reaction a + b "³ ab. Eventually, the product's energy will have a lesser amount of energy; . However, there are other factors contributing to this phenomenon. If the required amount of energy to start this reaction is 2x, the energy must be added from an outside source. Vapor pressure is caused by molecules that escape the surface of a liquid and enter the gas phase. Once started, the boulder will continue on its own until it has no reactant left. With this in mind, there comes into play two repulsing forces: the force exerted by the surface tension and gravity. These factors come into play through a model called collision theory.
