9. The concentration of carbon dioxide in the atmosphere has been increasing since the industrial revolution. In 2001, the concentration was 369 ppm (parts per million) and today (in 2019) it is 413 ppm. Assuming that the mass of the atmosphere is 5.2 x 1018 kg and has an effective molar mass of 29.0 g/mol (~80% N2, 20% O2), how many kg of CO2 have been added to the atmosphere since 2001? Note: 1 ppm = 1 umol per mole...
When carbon is burned in air, it reacts with oxygen to form carbon dioxide. When 27.6 gg of carbon were burned in the presence of 90.3 gg of oxygen, 16.7 gg of oxygen remained unreacted. What mass of carbon dioxide was produced? Express your answer to one decimal place and include the appropriate units.
Concentration of CO2 in the Atmosphere Levels of carbon dioxide (CO2) in the atmosphere are rising rapidly, far above any levels ever before recorded. Levels were around 278 parts per million in 1800, before the Industrial Age, and had never, in the hundreds of thousands of years before that, gone above 300 ppm. Levels are now nearing 400 ppm. Table 1 shows the rapid rise of CO2 concentrations over the last 50 years, also available in CarbonDioxide.1 We can use...

What is the equilibrium concentration of carbon dioxide in water that is in contact with air at 25 °C and 2.72 atm. The mole fraction of CO2 in air is 3.01×10-4. The Henry's law constant for carbon dioxide is 4.48×10-5 M/mmHg. A.2.79×10-5 M B.3.67×10-8 M C.9.26×10-2 M D.0.622 M E.6.72 M
The partial pressure of carbon dioxide in air is approximately 10^-3.42 atm. In temperate regions the pressure of CO2 in gas can be as high as 10^-1.5 atm. For each of these two cases, calculate the mass of carbon dioxide (in grams) in 1.0 m^3 of gas at 25 Celsius.
When methane (CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH4(g)+O2(g)→CO2(g)+H2O(g) This type of reaction is referred to as a complete combustion reaction. What mass of carbon dioxide is produced from the complete combustion of 4.50×10−3 g of methane? Express your answer with the appropriate units.
