Separating a Mixture of Compounds Exp. No. 2 name Chemistry 145 February 2‚ 2014 I. Purpose The purpose of this experiment was to separate this mixture into components‚ determine the mass and percentage of each component. In addition to test the accuracy of an alternative method of subtraction to find the mass of the sodium chloride directly. Start with a mixture of sand (SiO2)‚ sodium chloride (NaCl)‚ and ammonium chloride (NH4Cl)‚ and use these separation processes: sublimation filtration

NEWTON’S SECOND LAW OF MOTION Abstract This study’s objectives are first to verify the direct proportionality of acceleration and net force if the mass of the body is constant and then to verify the inverse proportionality of acceleration and mass if the net force is constant. With the use of‚ mainly‚ the dynamics cart and the weight hanger‚ certain variables such as the mass on the cart and the mass on the hanger which is the net force were manipulated‚ controlled or changed in order to illustrate

Experiment 9- Thin Lenses Introduction Experiment 9 introduced us to the concept of thin lenses. We were asked to determine the focal lengths of two converging lenses and one diverging lens. The following equations were used to calculate the focal lengths: 1/p + 1/q = 1/f where p is equal to the distance of the object from the lens and q is equal to the image length from the lens‚ and f is the focal point and 1/converging F+ 1/diverging F = 1/combined. The focal point is positive for converging

Chemical and Physical Processes of Digestion exercise T 8 he digestive system is a physiological marvel‚ composed of finely orchestrated chemical and physical activities. The food we ingest must be broken down to its molecular form for us to get the nutrients we need‚ and digestion involves a complex sequence of mechanical and chemical processes designed to achieve this goal as efficiently as possible. As food passes through the gastrointestinal tract‚ it is progressively broken down
