Empirical and Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical

Language is central to every single culture on Earth. Not only is it the human race’s main method of communication‚ it also is the only truly accurate way to record the human experience with integrity. Therefore‚ language shows most everything about who we are‚ from one’s homeland to education and everything in between. For instance‚ in Firoozeh Dumas’ The ‘F Word‚’ a young Iranian girl is judged for who she is without any of her contemporaries taking a moment to figure out why. By not having a

Firoozeh Dumas and Mawi Asgedom both tell their experiences of coming to America. While both Dumas and Asgedom discuss valuable stories of coming to America‚ they use different strategies to convey their perspectives. In “Funny in Farsi” Dumas focuses on her experience in America‚ she explains how so many people asked her questions. She also tries to entertain the reader while explaining her story. Dumas uses an Idiom to tell her encounter with two boys. They wanted to know curse words in Dumas’ language

Lab report: Viscosity of Liquids Introduction This experiment focuses on measurements of different trials of various concentrations. The collected data is used to compare and contrast to the ideal binary solutions and their components. The Ostwald viscometer is a useful laboratory equipment to measure the viscosities of many binary solutions. Background Molecules have the ability to slide around each other‚ result in a flow. Such a flow has a resistance called viscosity. Microscopically

environmental temperature. Acid hydrolysis was carried out through reflux boiling for 20 minutes with 10ml 0f 1.5M concentrations of diluted sulphuric acid. Reducing sugars concentrations were determined by spectrophotometry using the 3‚ 5 dinitrosalicylic acid (DNS) method. The first sample was operated as blank for zero. The stock solution was prepared in order to find the unknown concentration of carbohydrate cereals powder‚ jam (total sugar content) and jams (reducing sugar content). The absorbance

In this project one of the methods of digital forensic investigation is discussed which is memory imaging analysis. The analysis of volatile memory image is chosen over the Live Response approach of investigation.

of unknown volatile liquid under known temperature and pressure. Introduction Molar mass or gram molar mass is the mass of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of the gas is found under known temperature and pressure. Method/procedure

Alex Dumas Alex Dumas is one of the least credited generals of the French army in the French revolution. What makes him further significant was his unfair odds of obtaining such a status; he was the black son of a slave woman and nobleman. Because of his conditions‚ Dumas was able to have an understanding of virtually all perspectives of the French Revolution. It is important to study the life of Dumas to become aware of racial discrimination as well as how it can be overcome. Dumas was
