Formula One In May 2009 Max Mosley‚ then President of the Federation Internationale de l’Automobile (FIA)‚ declared that “the sport could survive without Ferrari.”1 Incensed by such brazen disregard of the team’s influence and further angered by proposed changes to the competition’s format‚ Ferrari announced that it did not intend “to enter its cars in the next Formula One world championship.”1 By June‚ eight of the ten F1 teams had declared their intention to join Ferrari’s breakaway championship

Sean Dowling Julia Phaltankar Mrs. Oakes Chemistry w/ Algebra 10/G February 18‚ 2015 Determining Empirical Formula Lab Introduction: One can find an empirical formula by taking a sample of a compound and dividing the number of moles of one element in the compound by the number of moles of another element in the compound to form a small wholenumber formula. For example‚ in a sample of a made up compound of oxygen and lead‚ one mole of lead has a molar mass of 207.2 g/mole‚ and oxygen

"Why the Fries Tastes Good"‚ Eric Schlosser introduces the readers to the flavor industry. Staying behind the curtains‚ the industry is the backbone to most of the delicious taste in processed foods in America nowadays. With a history dating back to when humans first realized the importance of spice trading‚ the artificial flavor industry has gradually become a growing industry whose members consider their trade an art form. Starting out with an example about how McDonald’s new fries recipes cooked

Empirical Formula B2 Honors 12/18/13 Abstract In this lab‚ to help better understand the concepts of gram atomic masses and empirical formulas‚ we found the gram atomic masses and empirical formula of a binary compound. The two compounds should form a definite whole number ratio by mass. This ratio will also help determine the subscripts of the elements in the empirical formula. Errors in this experiment can stem from measuring wrong or doing equations incorrectly. Procedure First

structure is derived. Firstly it is important to determine the percentage composition of elements to work out the empirical formula. The empirical formula was found to be C10H12O and the mass of the unknown was 148.09 m/z which when calculating the molecular weight of the empirical formula it did equal 148.09 g mol -1. This means that the empirical formula is also the molecular formula. As 12.01x10 carbons +1.008x12 hydrogens + 16= 148.09 09 g mol -1. From this knowledge the unknown molecule must include

Designing & Delivering On-the-Job Training Design Steps The quality of any training effort is based largely on whether it is thought through and planned before any action is taken. A simple five step process‚ representing the basic instructional design principles‚ can help ensure success. Training Location Leaders are expected to have a basic knowledge of these steps and apply them to the training activities they conduct. This does not mean that each time you conduct OJT with an employee some formal
