Laboratory 3. Empirical Formula Of An Oxide This experiment will demonstrate the law of conservation of mass‚ and more specifically‚ how the law can be used to experimentally determine the empirical formula of our intended product‚ magnesium oxide. In this experiment we will learn how to: 1. heat a sample in a crucible with a Bunsen burner. 2. use the method of weight by difference to determine mass quantities. 3. convert grams to moles. 4. determine the simplest ratio between two

Determination of the Formula of Magnesium Oxide. Introduction: Magnesium is a mental‚ it is known to react with oxygen. Magnesium reacts vigorously when heated in the presence of air‚ which is why we have chosen high heat in our method to facilitate combustion. This oxidation reaction produces magnesium oxide gaining oxygen from the air. When sharing of electrons occur a chemical bond is made and the atoms combine to form a molecule. So‚ the predicted molecular formula: Mg + O2--------->

INDOOR AIR QUALITY (PUBLIC AWARENESS) Indoor air is often considered safe and free from pollutants. But most people have the greatest contact with toxic pollutants not outside but inside their homes and offices. The modern consumer products like air fresheners‚ cleaning compounds‚ moth repellants‚ cigarettes‚ toilet disinfectants or deodorizers are the most common sources that laden the indoor air with toxic pollutants without anyone even suspecting them or their potential.

programming. Commercial organizations use mathematics in accounting‚ inventory management‚ marketing‚ sales forecasting‚ and financial analysis. In Academia‚ "Business Mathematics" includes mathematics courses taken at an undergraduate level by business students. These courses are slightly less difficult and do not always go into the same depth as other mathematics courses for people majoring in mathematics or science fields. The two most common math courses taken in this form are Business Calculus and Business

When comparing the similarities and differences between virtue theory‚ utilitarianism‚ and deontology we find that they all deal with how one judge’s morality and ethics. These theories all include judging in different aspects‚ whether it is in the moment‚ what happens after‚ or over a lifetime. The ethics and morality behind these theories all deal with what is right‚ or what is best for the present‚ then separate paths as the theories work toward the future. With virtue ethics a person strives

In this passage from Jon Krauaker’s Into Thin Air‚ Jon Krauaker does not display the sense of accomplishment that one would expect from achieving such a difficult endeavor. He really displays a sense of grief and dissatisfaction from what he had accomplished. For taking a risk as life threatening as this‚ in Krauaker’s eyes‚ he couldn’t possibly be proud of what he had done when so many men had lost their lives during the same excursion that he journeyed on. Throughout this novel‚ Jon Krauaker

important considerations when assessing students’ threats made at schools. In recent articles‚ M. Reddy et al. (2001) presented four approaches to assessing the risk of school violence. Three commonly used approaches was submitted with an alternative 4th approach suggesting a more logical alternative approach that should be taken more into consideration when assessing threats in school violence. The 1st approach is Behavioral profiling- assessing students behavior‚ physical‚ demographics‚ personality
