acquainted the different instruments used to measure specific gravity and report measurements and calculations accurately. The materials used in this experiment are: pycnometer‚ Leach pycnometer‚ Baumme Hydrometer and Mohr Westphal balance. Specific Gravity of each material are then calculated using the values obtained. Guide Questions: 1. Differentiate specific gravity and density. Specific gravity is the ratio of a material’s density with that of water at 4 °C where it is most dense and is taken to

Laboratory safety regulations 1) Corrosive acids and alkali must be treated carefully‚ and be sure not to splash on clothes‚ skin and eyes. While diluting strong sulfuric acid‚ the acid should be poured slowly into the water with stirring‚ but not water into the acid. 2）It’s not allowed to handle solid drugs with the hand directly.

equilibrium. Most ocean surface waters are supersaturated in aragonite‚ and deep waters are under-saturated due to the decrease of CO32- and increase of Ksp* with depth. As the ocean becomes more acidic‚ the value of Ω will decrease. Experimental measurements show that a decrease in Ω or [CO32-] makes it more difficult for calcifying organisms such as corals to produce CaCO3(s)

weapon. It is not to be confused with ballistics - which is the study of a projectile in motion. Bullet Comparisons – The inner surface of the barrel of a gun leaves its markings on a bullet passing through it. The gun barrel is produced from a solid bar of steel that has been hollowed by drilling. The microscopic drill marks left on the barrel’s inner surface are randomly irregular and impart uniqueness to each one. The manufacture of a barrel requires the additional step of impressing its

The objective of this experiment was to learn the process of recrystallization and how this process removes the impurities from a pure solid compound. The methods used to achieve this objective were also hot vacuum filtration in order to remove suspended solid impurities‚ and isolating the pure acetanilide. In the next lab‚ percent recovered was obtained through weighing the acetanilide sample as well as comparing its melting point range. In this experiment‚ the sample‚ acetanilide was weighted

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous
