The History of the Atom Hypothesis according to Aristotle (350 BC): All matter consists of the elements earth‚ air‚ fire‚ and water. Experiment: A tree grows from the earth as water is added. The tree is then set on fire in an effort to form new elements. 1. What kind of results would be observed from this experiment? Fire‚ ash (earth)‚ smoke (air) 2. Would these observations support or reject the hypothesis? Explain. Support. No elements have been produced that are something other than

A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes can

This type of reaction is an oxidation-reduction (or redox) reaction. This reaction is also [anabolic/catabolic] and [endergonic/exergonic]. In redox reactions‚ electrons (and associated H ions) are transferred from one compound or element to another. If one compound or element loses electrons and becomes oxidized‚ another must gain electrons and become reduced. For example‚ in photosynthesis‚ water becomes [oxidized/reduced] (to O2) and the electrons (and associated

AK/ADMS 4541 Advanced Corporate Finance Winter 2013 Mid-Term Exam Answer Key Question 1 (35 marks) a.) b.) (8 marks) (4 marks) Calculating the EOQ. EOQ = SQRT(2 * F * T / H) = (2 * 80 * 200‚000 / 1.00)0.5 EOQ = 5‚656.85 kg (4 marks) Calculating the EOQ savings. Total cost = (F * T/Q) + (H * Q / 2) = (80 * 200‚000 / 10‚000) + (1.00 * 10‚000/2) Total Cost @10‚000 kg = $6‚600 Total Cost EOQ = (F * T / Q) + (H * Q / 2) where Q = 5‚656.85 kg = (80 * 200‚000 / 5‚656.85) + (1.00 * 5‚656.85 / 2) = $5‚656
