Cobalt(II) Oxygen adduct complex Inorganic 461 lab 2-29-2012 Abstract This experiment uses Co(salen) as a model compound illustrating the uptake of oxygen in hemoglobin. SalenH2 was prepared as the intermediate‚ and reacted with hydrated cobalt to prepare Co(salen). Using Co(salen) the oxygen up-take was tested. The synthesis of SalenH2 produced 0.65 g. The percent yield of salenH2 was 116% on the filter paper and 105% after transferring salenH2 to a vial. The melting point of salenH2‚ was

Impact of carbon footprint assessment for the economic sector of domestic as per household usage Carbon dioxide is a greenhouse gas - it traps the sun’s heat and keeps the earth warm. Too much CO2 in the air leads to climate change‚ also known as global warming. Other greenhouse gases‚ such as methane‚ also contribute to climate change. Countries and organizations count these as part of their carbon emissions. But for individuals the most important carbon emission is carbon dioxide. It’s well

Dracca became aware that one of its competitors‚ TrendBaby‚ Inc.‚ was soliciting information from one of Dracca’s employees‚ Bob Shumaster. Shumaster was apparently detailing product assembly information that was unique to Dracca and explaining to TrendBaby how this assembly strategy saved Dracca thousands of dollars each month. Dracca discovered that TrendBaby actually hired Shumaster to provide this information‚ and that Shumaster was using Dracca company computers to relay the proprietary information

Carbon is a part of your daily life Alice Cui E10M Carbon plays an essential role in people’s daily life. The cosmetics we use‚ the food additives we consume in snacks‚ the diamond we wear on our ring‚ the oil we use to fuel our cars‚ and even the DNA in our body are made up of carbon. The reason carbon exist in so many substances is its electron configuration. Carbon has 4 valence electrons and that means it can lose or gain electron to form stable structure easily. In this essay‚ I am going to

Carbon Monoxide Carbon Monoxide (CO) Carbon monoxide is a colorless‚ odorless‚ tasteless and toxic gas produced as a by-product of combustion. Any fuel burning appliance‚ vehicle‚ tool or other device has the potential to produce dangerous levels of carbon monoxide gas. Examples of carbon monoxide producing devices commonly in use around the home include: • Fuel fired furnaces (non-electric) • Gas water heaters • Fireplaces and woodstoves • Gas stoves • Gas dryers • Charcoal grills
