Dear sir‚ Importance of STPM In response to your article published on 10th of June I strongly disagree with the writer. Studying for STPM is never a waste of time as what the writer states. Here I would like to express my viewpoint about this matter. 2. I am of opinion that STPM students have better opportunities of applying for local public universities when compared to SPM candidates. Students with STPM qualification can also apply for local private colleges and universities.

September the 11th 2001. Four airliners‚ hijacked to implement acts of terrorism against targets in the United States of America. The product of this: 2900 fatalities and a limitless figure on those traumatized. Over a decade later the wounds inflicted by 9/11 remain raw. It is perhaps one of the most controversial‚ revolutionary and conspiracy ridden events in human history. AL Qaeda is defined as a broad-based militant Islamist organization‚ and is considered to be- by the majority of society-

A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

After I read about the Vietnam Wars I can infer that the Vietnamese people and culture over the centuries have been very proud and have stayed almost the same over the time periods of war and struggles. It all started in 208 B.C. from what I have read. The Vietnamese people were first invaded by China time and time again and continuously being pushed around. Every single time the Chinese invaded Vietnam‚ Vietnam became a territory of the Chinese. Every single time a rebellion would end up sparking

Introduction The purpose of this lab is to determine which pigments in a plant support or effect photosynthesis‚ based on starch production‚ which wavelengths of light are involved in photosynthesis‚ and identify plant pigments found in a plant leaf by means of paper chromatography. Life on Earth is dependent entirely on the energy from the Sun‚ not only to keep the planet at a suitable temperature but also to provide the energy required to sustain life. The energy of the Sun‚ in the form of

RECRYSTALLIZATION Group Medical Technology Organic Chemistry Laboratory ABSTRACT Recrystallization is one of the simplest and most widely used technique for purifying organic solids through the differences in solubility at different temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride
