- What is the biological importance of stratospheric ozone? Explain.arrow_forwardHow does hydraulic fracturing differ from previously used techniques for the recovery of natural gas from the earth?arrow_forwardMass of CO2 formed early = 1.2 x 106 g The world burns approximately 3.8×1012 kg of fossil fuel per year. The previous two statements were either given or solved for in part a of the question. The following is the question asked in part b. The current concentration of carbon dioxide in the atmosphere is approximately 376 ppm (by volume). By what percentage does the concentration increase each year due to fossil fuel combustion? Approximate the average properties of the entire atmosphere by assuming that the atmosphere extends from sea level to 15 km and that it has an average pressure of 381 torr and average temperature of 275 K. Assume Earth is a perfect sphere with a radius of 6371 km. Express your answer to two significant figures and include the appropriate units.arrow_forward
- In the atmosphere, is it more common to find two oxygen molecule to joined together than find a single atom of oxygen. Why? What would that molecule look like? What would this molecule be called?arrow_forwardWhy is the composition of the atmosphere is not uniform?arrow_forwardIn February I travel 100 miles everyday In June I travel 5 miles a week. My car gets 28 miles per gallon. Please show steps Using your cars miles per gallon and the miles you drive in 1 week calculate the liters of carbon dioxide you produce when using your car. Compare your miles in February (pre-covid) versus June (post-covid). Assume that your engine combusts at 1.00 atm and 25.0 celsius. Assume that your gasoline is 100% octane (C8H18). You will also need to balance the combustion reaction that occurs in your car engine. You will need to use PV=nRTarrow_forward
- If a small volume of a particular liquid was to react with the oxygen in the atmosphere, which container would allow for the reaction to occur the most quickly?arrow_forwardWhat is an ionic atmosphere?arrow_forwardGiven the following reaction of Ca(s) in HCl(aq): Ca(s) + 2 HCl(aq) --> CaCl2(aq) + H2(g) If 32.7g of calcium solid are placed in this reaction and at the end of the experiment, hydrogen gas is produced at 25.000C and with a pressure of 790. mmHg. Calculate the volume of hydrogen gas produced.arrow_forward
