The production of cement results in significant GHG emissions. The emissions are caused by the decomposition of calcium carbonate (limestone) to calcium oxide (lime) and carbon dioxide. This process known as calcination, is carried out in kilns. Therefore, additional GHGs are emitted as a result of heating the kilns. A large cement manufacturer uses a mix of coal, natural gas, and biomass in its boiler. This mix produces the following amounts of GHGs per Million BTUs of energy: • 250 lbs CO2/MMBtu • 5 lbs CH4/MMBtu • 0.36 lbs N2O/MMBtu Process carbon emissions from the calcination process produce 925 lbs of carbon dioxide per metric ton of cement. In addition, the plant uses 1.7 Million BTUs of energy per metric ton of cement. If the plant produces 180,000 metric tons of cement annually, how many metric tons of CO2e does it emit?

A sample of unknown gas was heated to 125°C in a round bottom flask at standard pressure (1.00 atm), and its weight in a 100 ml round bottom flask was taken to be 30.098g. The round bottom flask weighs 30.0g. The gas was determined to be pure so that it can only be composed of a single element (N2, O2, F2, He, Ne, Ar, P2, S2, Cl2). Identify the gas.
