Pre-Lab Discussion An empirical formula is a formula for a chemical compound found by direct laboratory examination. Laboratory procedures allow the chemist to find the simplest whole number ratio of elements within the compound. In order to find the true molecular formula‚ the chemist also needs to know the compound’s molecular mass. The general procedure is to use laboratory techniques to determine the mass of each element in the compound. In this lab‚ we will react a known quantity of magnesium

Karthik Keni William Reckner Philosophy 22 30 November 2010 Kant: Formulas of Universal Law and Humanity Kant’s philosophy was based around the theory that we have a moral unconditional obligation and duty that he calls the “Categorical Imperative.” He believes that an action must be done with a motive of this moral obligation‚ and if not done with this intention then the action would hold no moral value. Under this umbrella of the “Categorical Imperative” he presents three formulations that he

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--------->

Deriving the Credit Card Debt Formula We will approximate a formula to calculate our account balance over time 10000 + 10000*(.12/12) assuming we have a $10‚000 balance on the card. We will assume a 12% APR‚ and will also assume that we are only paying 2% of our monthly balance. This is because credit cards ask you to only pay 2% of your debt at a time so that you keep your balance high and they get more interest from you! Month 1: 10000 + 10000*(.12/12) This is our original $10000 we borrowed

Formula Sheet (Including the stuff not on the real formula sheet) From Gauss’ Law Flux perpendicular r to E is equal to zero. Flux entering a surface is negative. Flux leaving a surface is positive. The flux entering a surface is the same as the flux leaving it.

Peter Singer‚ believes that people who are wealthy‚ and live a luxurious lifestyle should donate their money to overseas aid organizations‚ and although Singer believes “the formula is simple”‚ I disagree. When Singer states that giving away money is an easy thing task‚ I believe that even for the prosperous it is not. Not for the fact that they don’t have the money‚ but for the fact that the need for food and medicine is far too great‚ and dispersed around the world that not everyone would receive

Unknown 8-28-12 Finding the Prosperity by Feeding Monkeys In the short story‚” Finding Prosperity by Feeding Monkeys”‚ by Harold Taw‚ Taw explains a moral about the importance of family‚ and how some people will break whatever rules to respect their family. Taw states that a Buddhist monk told his parents that he [Taw] would bring great prosperity to the family if he fed a monkey on his birthday every year for the rest of his life. Every year Taw made a point to feed a monkey on his birthday
