Good evening everyone! I remember when I was in 4th year high school‚ I’ve practiced my declamation speech for a week‚ and the performance they arrived‚ my speech is entitled- Am I to be blamed? Here are some lines of the speech: “They’re chasing me‚ they’re chasing‚ no they must not catch me‚ I have enough money now‚ yes enough for my starving mother and brothers. Please let me go‚ let me go home before you imprisoned me.” These were the few lines of my declamation piece. And these few lines

TITLE Crime and Dye Lab Special Projects 1 Martin Enem LAB SECTION: BB2 INTRODUCTION Light is usually viewed as a result of the heating of a substance. The higher the temperature at which the substance is heated‚ the greater the vibrations that lead to certain light intensity given off by the molecule. It is this same theory that suggests why steel glows red hot when heated to high enough temperatures. The process of light emissions can also be induces through other means. 1 One

Introduction There are many different factors that can influence the rate of diffusion through a membrane. Chemical kinetics plays a large part in diffusion. In order for a solute to passively diffuse through a membrane‚ it must line up with a pore in the membrane and pass through it (textbook 101). The concentration gradient is also important for diffusion because solutes diffuse from areas of high concentration to areas of low concentration (textbook page 101). There are different factors that

Abstract This study was undertaken to determine the effects of different environments affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency

Abstract This report investigates the absorbance of methylene blue and carmine red using a spectrophotometer to determine the absorption spectra of both solutions. The concentration of the unknown solution of methylene blue was found to be 1.07 x 10-5 M by using the molar extinction coefficient‚ with absorption of 0.547. It was also found that the results concluded confirmed beer’s law with an R2 value of 0.9989. Introduction Spectrophotometry is the quantitative measurement of the absorbance
