The purpose of this lab was to find the empirical formula for magnesium oxide. To find this formula‚ a strip of Magnesium ribbon was burned in a crucible over a flame from a bunson burner. After the strip caught fire multiple times with the cover on‚ and 10 drops of distilled water were added‚ and the crucible was lightly heated. The crucible was then weighed and the mass recorded. Calculations were performed and the mole ratio of Mg to O was recorded. The results of other lab groups performing

SEMI-FINAL LECTURE NOTE 02 CREATING SIMPLE FORMULAS Formula. A formula is a group of symbols that make a mathematical statement. A formula can be a combination of values (numbers or cell references) and math operators (+‚ -‚ /‚ *‚ =) into an algebraic expression. Excel requires every formula to begin with an equal sign (=). The following table illustrates the mathematical operators learned in school and those represented in Excel 2003. | |School

learned before on how to determine the empirical formula of a compound based on the test and also chemical analysis on it. Hence this experiment is mainly goes around with how to determine the empirical formula of Magnesium Oxide following various tight procedures in order to get the knowledge and apply it onto another compounds. We are investigating the empirical formula of Magnesium Oxide in this experiment. RESEARCH QUESTION: How empirical formula of Magnesium Oxide is obtained by heating Magnesium

Running head: QUADRATIC FUNCTIONS 1 Real World Quadratic Functions Gail Frazier MAT 222 Week 4 Assignment Instructor: Simone Danielson March 6‚ 2014 Real World Quadratic Functions [no notes on this page] -1- QUADRATIC FUNCTIONS 2 Quadratic functions are perhaps the best example of how math concepts can be combined into a single problem. To solve these‚ rules for order of operations‚ solving equations‚ exponents‚ and radicals must be used. Because multiple variables

Melissa Carrithers 9-17-14 Period: 6 Determination of the Empirical Formula of Silver Oxide Purpose: To find the percent composition and empirical formula of silver oxide can then be calculated‚ based on combining the ratios of silver and oxygen in the reaction. Hypothesis: Silver oxide decomposes to silver metal and oxygen when strongly heated. Heating Silver oxide causes the oxygen to be driven off‚ leaving only the silver metal behind. The total mass of the products of a chemical reaction must

Lillian Zhang AP Chemistry 3rd Period Formula of an Unknown Hydrate The purpose of the Formula of an Unknown Hydrate lab is to determine the weight percentage of H2O hydrated to an unknown salt and the empirical formula for the hydrated salt. To do this‚ a massed amount of the hydrate is heated over either a hot plate or Bunsen burner. This causes the water to be removed‚ leaving the anhydrous salt behind in the dish. The mass of the anhydrous salt‚ now with the absence of water‚ is less than

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
