... Carbon monoxide is a colorless and odorless asphyxiant that combines with the hemoglobin in the bloodstream causing a decrease the amount of oxygen delivered to the tissues. This can lead to dizziness, loss of consciousness and in some cases—death. In the United States, 75% of CO emissions come from ...

Carbon Farming
... “Carbon farming” is an umbrella term for agricultural practices that aim to remove more greenhouse gases (GHGs) from the atmosphere than they emit. Through the process of photosynthesis, agricultural crops pull carbon dioxide from the atmosphere and then lock that carbon above ground (through crop r ...

... 1. A 15.40-g sample of a finely-divided mixture of only Fe2S3 and FeS was reacted with excess H2 at elevated temperatures. If the weight percent of Fe2S3 in this mixture is 57.4%, then calculate the total mass in grams of Fe that can be produced. Assume the only other product of these reactions is H ...

... Most organic compounds have a low volatility –they do not readily evaporate. However, low-molecular-weight, nonpolar molecules have the greatest vapor pressures of organic compounds. ---Think nail polish remover or gasoline---. The partitioning of an organic compound between liquid and vapor is ofte ...
