genuine United States legal tender coins. The purpose of this experiment is to determine the accuracy of the copper and zinc composition percentages in a random sampling of pennies. The penny was dissolved to make aqueous copper ions and four copper dilutions were made from stock solution. Each cuvette sample was measured in a colorimeter and the data was plotted linearly using Beer’s law plot. Mass percent and percent error were found using calculations. Analysis of class data provided further data to

1. SURFACE RUNOFF INTRODUCTION: Runoff means the draining or flowing off of precipitation from a catchment area through a surface channel enters into a stream channel. It is convenient to visualize three main routes of travel; overland flow (air hujan limpahanpermukaan)‚ interflow‚ and ground water flow (air dari punca bawah tanah). 1 Runoff results from rainfall occurrence in a hydrologic catchment. Rainfall-runoff relations are Interflow/subsurface and base flow/groundwater flow

Antibiotic Sensitivity lab A. Define the term selectively toxic. Why is it an important feature of antimicrobial agents? Selective toxicity is the ability of a chemical or drug to kill a microorganism without harming its host. Selective toxicity is important to microbial agents because it enables these agents to inhibit or kill a microorganism by interacting with microbial functions or structures different from those of the host thereby showing little or no effect to the host. B. What

Also nuclear chemistry has some other methods that deals with nuclear medicine called analytic methods which are using radioactive isotopes for biological tracers and using isotopes for dilution. Radiation can have beneficial and harmful effects towards organisms‚ and it normally be applied in the form of dosages. It is said that as the dosages increase the greater the effect the radiation has upon the body‚ effects can be with having good

FACTORS AFFECTING SOLUBILITY There are three main factors that control solubility of a solute. (1) Temperature (2) Nature of solute or solvent (3) Pressure EFFECT OF TEMPERATURE Generally in many cases solubility increases with the rise in temperature and decreases with the fall of temperature but it is not necessary in all cases. However we must follow two behaviours: In endothermic process‚ solubility increases with the increase in temperature and vice versa. For

MATERIAL AND METHODS Stability of cell membrane using pH For the lab experiment for testing the stability of beet cell membranes using pH‚ many materials were used as follows. Obtaining a beet we punch out cores‚ using a cork borer. After washing the cores we put each one inside a separate test tube‚ and added a different pH solution in each one. After 3 minutes in these exposure solutions‚ we took the beet out with a dissecting needle. Then transferred each beet to a separate test tube containing

Blood Cell which is an indicator of the presence of virus. ■ Magnitude of the agglutination depends on quantity of virus. ■ Two fold serial dilution of the suspected virus material in P.B.S is treated with 1% washed R.B.C.s. ■ Virus agglutination can be seen in micro titration plates. ■ Reciprocal of the last virus dilution giving agglutination is Haemagglutination titer (HA titer).
