Water pollution is the contamination of water bodies (e. g. lakes, rivers, oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also …
Importance of Surfactant Introduction Surfactant is an essential component for the respiratory system to function properly. Knowing the physiology of surfactant in the alveoli is important to know when learning the structure of the air sacs and how they work. This experiment is designed to …
A waste is considered toxic or hazardous if it threatens the health of the people and the destruction of the environment. The waste may be in any form and may be considered toxic even upon its storage. A more distinct characteristic of a toxic waste …
Aaron Wong History and Development of the Periodic Table Period 11 The most basic arrangement of the periodic table was in 1649. By this time, many elements have been known but the first scientific discovery of an element was in 1649. Hennig Brand discovered phosphorus, …
CHAPTER I INTRODUCTION 1. 1 Background Food is one of human sources of calorie, protein, fats, and nutrition. Yet, because of the highly nutritious content, food is susceptible to growth of microorganisms. By the presence of microorganisms in food, the food is more likely to …
Introduction The purpose of this experiment is to demonstrate an example of how to determine the unknown molarity of hydrochloric acid by titration with a base (sodium hydroxide). Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown …
The leaves are the part of a plant where most photosynthesis takes place. Key: 1. Waxy cuticle: this gives the leaf a waterproof layer, which lets in light. 2. Upper epidermis: provides an upper surface. 3. Palisade cells: contain chloroplasts. 4. Spongy mesophyll: collection of …
My aim in this experiment is to see how well an enzyme (phosphatase in this case) reacts under a controlled temperature but a varying pH. Enzymes are known to be effected by pH and temperature. Both of these change how quickly the enzyme can process …
Importance of colloidal dispersion in pharmacy Pharmaceutical Applications of colloids: Colloids are extensively used for modifying the properties of pharmaceutical agents. The most common property that is affected is the solubility of a drug. However, colloidal forms of many drugs exhibits substantially different properties when …
The experiment conducted, isolation of eugenol from cloves, is the extraction of the essential oil. To perform this experiment cloves and water were mixed together and heated by a heating mantle in a round-bottom flask. A direct stem distillation took place, and the oil product …

Conjugation
The word "conjugation" is derived from a Latin word that means "to link together". In organic chemistry terms, it is used to describe the situation that occurs when π systems (e.g. double bonds) are "linked together". An "isolated" π (pi) system exists only between a single pair of adjacent atoms (e.g. C=C)
Kinetic energy
Kinetic energy is the energy associated with objects in motion. Potential energy is the type of energy associated with an object's potential to do work. Chemical energy is the type of energy released from the breakdown of chemical bonds and can be harnessed for metabolic processes.
Physics
Chemical physics is concerned with the application of the concepts and theories of physics to the analysis of chemical systems and their physical behaviour. While also at the interface between physics and chemistry, it is distinct from physical chemistry.
