Everyday there is a change in prices of a good due to economic changes. The outcome of any situation determines the price of a good. There are three types of elasticity of demand that each good has, which are elastic, a situation in which the supply and demand for a good or service can vary […]

Objective: In this lab we will analyze alum by two techniques in order to verify its identity.  The melting point and the mole ratio of hydrated water to anhydrous aluminum potassium sulfate will be determined. Lab Procedure: Use a mortar and pestle to crush alum. Pack the alum in capillary tube, and then fasten it […]

Lab objective: In this experiment, the percent composition and empirical formula of silver oxide will be determined. Silver oxide will be heated until it decomposes to silver metal and oxygen, and the percent calculation and empirical formula can be calculated based on combining the ratios of silver and oxygen in the reaction. Summary of lab […]

India is among the top 5 producer of the most of the commodities in addition to being a major consumer of bullion and energy products. Agriculture contributes more than 23% to be GDP of Indian economy. It employees around 57% of the labor force on a total of 185 million hectares of land.Agriculture sector is […]

Introduction This laboratory exercise is dedicated to studying forced convection, a crucial aspect of heat transfer. Understanding the importance and impact of forced convection on heat transfer problems is a crucial learning objective in the field. One of the key aspects of forced convection is the convection heat transfer coefficient (denoted as h), which is […]

Objective: To separate the components of unsweetened, grape flavored Kool-Aid. Procedure: Using two syringes, inject different concentrations of alcohol to extract red and blue dyes, and artificial flavoring. Data: Conclusion: Different dyes are shown when separated by different concentrations of isopropyl alcohol. Discussion of Theory: Chromatography, resolution and selectivity played major roles in making the […]

Introduction A bending moment is an internal force that is induced in a restrained structural element when external forces are applied. Failure by bending will occur when loading is sufficient to introduce bending stress greater than the yield stress of the material. Bending stress increases proportionally with bending moment. It is possible that failure by […]

The objective of financial reporting is to deliver essential fiscal data concerning the company that is reporting. This information proves invaluable for both existing and potential investors, creditors, and other credit providers as it aids in informed decision-making when providing capital. Precise assessment, impartiality, and prompt disclosure of an organization’s financial standing can support appropriate […]

Problem Statement Miguel Vasquez, a new product manager for a biotechnology company, was handed with some competitive intelligence from another competing firm. The said information, handed to him by his boss, contained proprietary and confidential information that can give a competitive advantage to the firm. This information was obviously obtained using an illegal tap into […]

Calcium is a mineral which is essential to the human body. In fact 1. 5% of the human body is made up of calcium, and not just the obvious uses such as bone and teeth formation but it is also a vital factor in many enzyme reactions, for example blood clotting. It also partakes in […]

The objective of the experiment was to prepare Benzilic acid by multistep synthesis starting with benzaldehyde. In this setup however, product of the first step, Benzoin, is provided thereby omitting the first step involving the conversion of benzaldehyde. For this experiment, the microscale techniques of reflux, crystallization, and melting-point determination were used. Utilizing these techniques […]

In the United States, there is a growing issue of obesity and overweight individuals. The prevalence of these conditions continues to rise annually. According to Anonymous (2011), approximately 33.9% of American adults are considered obese, while 34.4% are categorized as overweight but not obese. Consequently, more people are actively seeking alternative methods to shed pounds. […]

Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation, which involves mixing an alkyl or acyl halide with a Lewis acid, or acylation, which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because […]

AIMS /OBJECTIVES To understand the reactions of manganese To prepare Mn(acac)3 and calculate percentage yield To calculate the percentage of Mn and acetyl acetone and the empirical formula THEORY Manganese is a first row transition metal that has a tremendous variety of oxidation states that appear in its compounds. The oxidation numbers range from Mn […]

Investigatory Project Presented to the Department of Science and Technology By: Coleen Sioson October 2012 A. Experiment Description In this investigatory project, we will use eggshells as an alternative ingredient in chalk production. The study is very efficient in these days because many people are in need of chalk especially the teachers because they use […]

Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five-carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. […]

What evidence do you have to prove cellular respiration occurred in beans? Explain. The evidence you have is the color change that occurs in the beakers of beans. This occurs because of the use of bromothymol blue indicator that turns yellow when in acidic conditions, turns green when in neutral conditions and turns blue when […]

Research Design and Mythology The research design and methodology of the paper will be a qualitative style of research combined with statistical data. The author will use secondary data to gather the five methods of research: observations, interviews, survey forms, focus groups and internal data. The hope is to combine these methods and research findings […]

The eco-column lab serves as a valuable learning tool by allowing you to create and observe your own miniature world, demonstrating its similarities to the real world. It resembles the real world with communities of organisms and their environment. Additionally, it operates as a closed system where waste produced by one species must be utilized […]
