Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties‚ the dichromate ion (Cr2O72–) is the specified oxidant in Methods

Communicating Consumer Behavior - An Exercise Using Personal Consumption Journals In consumer behavior‚ it is vital that upon completion of the course students have acquired a sound understanding of how consumers search for‚ purchase‚ and use products and services. Furthermore‚ students should also be exposed to the social and psychological influences on these behaviors. Finally‚ to have garnered the most benefit‚ students should understand how to integrate the theoretical concepts into their real

If a plant makes 30 grams of glucose (C6H12O6)‚ how many moles of glucose has it produced? 0.17 moles The health of bones depends upon a good supply of calcium. If a person consumes 0.06 g of calcium‚ how many moles of calcium did he consume

Soda Consumption There are many studies today that show a link between obesity and regular soda consumption. Our study is about how regular pop consumption is more popular with young‚ nonwhite‚ low-income Americans. “Half of Americans aged 18 to 29 say they drink regular soda‚ making them the most likely to do so across not only age groups‚ but also across all major demographic and socioeconomic groups.” (galloppoll.com) Two groups known in America most likely to be obese according to studies

The power consumption for sending (or receiving) a single message in a mobile phone Abstract: We measure overall SMS‚ Whatapps and Wechat for the power consumption of a single message. These results are validated by overall power measurements of two other devices: the Battery Doctor and Battery Detective. We discuss the significance of the power drawn by the various length and time of texting messages‚ and identify the most promising areas to focus on for further improvements of power management
