(polyethylene). For example‚ ethene can react with water to form ethanol‚ with a H3PO4 catalyst at 300oC. Ethene can react with oxygen in the presence of an Ag catalyst and at 250oC‚ to form ethylene oxide‚ which is further treated with dilute acid solution to form ethylene glycol. Ethene can also react with oxygen‚ with a copper chloride catalyst and at 150oC‚ to form vinyl chloride (chloro-ethene) Identify that ethylene serves as a monomer from which polymers are made Ethylene is the monomer which

Engineering lettering Pencil Techniques * The best pencils for lettering on most surfaces are the H‚ F‚ and HB grades. * Hold your pencil in the position shown. It should make approximately a 60o angle with the paper. Pencil Lead Designation Freehand Lettering * Developing good lettering is a personal skill which takes practice. Letters must be formed properly. * They must be open shaped very legible. Clear communication is essential to avoid mistakes and reduce waste.

Jhavon Crenshaw Professor Madden English Composition 30 September 2012 Sound Engineering As a future audio engineer‚ it is in my best interest to learn the techniques of audio production. For editing sound you need the proper equipment‚ whether it is software or hardware. In order to give sound a little flavor you will need to know about mixing. Mastering is what ultimately completes the sound. Equipment‚ mixing‚ and mastering are the most important steps in audio production. The majority

Solution: i. Establishment of estimated growth rate in earnings and dividends. XYZ Company’s current EPS is $4.75. It was $3.90 a year ago. The company pays out 35% of its earnings as dividends‚ and the stock sells for $45. a. Calculate the past growth rate in earnings. b. Calculate the next expected dividend. Assume that the past growth rate will continue Answer: If payout ratio is constant‚ then dividend growth rate will be same as earnings growth rate. a) dividend growth rate over
