Acid Rain is a type of air pollution‚ which is formed when oxides of sulfur and nitrogen combine with atmospheric moisture to yield sulfuric and nitric acids‚ which may then be carried long distances from a source before they are deposited by rain. This pollution may also take the form of snow‚ fog‚ or a dry form of precipitation. Acid rain is currently a subject of great controversy because of widespread environmental damage‚ for which it has been blamed‚ including eroding structures‚ injuring crops

The acid-fast stain is performed on samples to demonstrate the characteristic of acid fastness in certain bacteria. Acid fastness is a characteristic that is shared by just a few organisms‚ so staining to determine if organisms possess this trait is useful in microbial identification schemes. The Ziehl-Neelsen method has endured as a reliable and effective way to demonstrate the acid-fast bacteria. Materials: 18-20 nutrient hour agar slant culture of Staphyloccus aureus 4 day old nutrient

Abstract The objective of this experiment was to observe multi-step purification of benzoic acid after performing the extraction from a mixture containing benzoic acid‚ cellulose‚ and methyl orange. Recrystallization was done to remove impurities from the sample. The amount of BA recovered during recrystallization is much less than the extracted amount of BA. The difference between the pure and impure samples was observed by comparison of melting points. It was found that impure samples will have

top. Sheep would quite often wander off the path of safety and become entangled in dense brush or slip into small gulleys and the crook enabled the shepherd to reach out for the sheep and draw it out of harm and back to the safety of the flock. Psalm 23 can be regarded as a psalm of high praise of God. It is one of the shortest psalms‚ but it gets its point across very directly and clearly. It makes use of the extended metaphor which is a metaphor that develops at length and includes several points

Characteristics and Properties of Amino Acids Introduction: Each amino acid has at least one amine and one acid functional group as the name implies. The different properties result from variations in the structures of different R groups. The R group is often referred to as the amino acid side chain. Amino acids have special common names‚ however‚ a three letter abbreviation for the name is used most of the time. A second abbreviation ‚ single letter‚ is used in long protein structures.Consult
