(a)
Interpretation:
Website for unhealthy ozone level should be identified.
Concept introduction:
The release of chloro flouro carbon from refrigerator and air conditioner and the pollutants emitted from vehicles enters the atmosphere and reaches to the stratosphere and degrades the environment and results in the depletion of ozone layer and if this ozone is present more than the threshold level in the vicinity of the people living in the area then it causes severe fatal diseases.
(b)
Interpretation:
The area of residence has healthy or unhealthy air should be identified.
Concept introduction:
The industrial area mainly having the bad quality of air due to the emission of various poisonous gases in the atmosphere and thus degrading the quality of air to make it bad enough for breathing.

- In Module #4, we discussed the role of chlorofluorocarbons (CFCs) in catalyzing the destruction of O3 in the stratosphere. One example of a CFC that is known to exasperate formation of the hole in the O3 layer is dichlorodifluoromethane (CF2Cl2). In the year 2000, this chemical reached its peak concentration of 2.2 x 10-11 M in the atmosphere. The destruction of CF2Cl2 can be approximated as a first-order process and the 1996 treaty on CFC emissions has eliminated its release into the atmosphere. Given that the rate constant for destruction of CF2Cl2 in the atmosphere is 0.009 yr-1, how long will it take for the concentration of CF2Cl2 to decline to 0.22 x 10-11 M?arrow_forwardRegarding the combustion of gasoline, 2C8H18 (l) + 25O2 (g) --> 16CO2 (g) + 18H2O (g) How could you reduce carbon dioxide emissions?arrow_forwardQUESTION 4 From the Coursebook: What is a useful marker point for the Global Anthropocene? When glacial sediments are replaced by organic sediments When Carbon Dioxide (CO2) and Methane (CH4) first get recorded in rocks and sediment When Carbon Dioxide (CO2) and Methane (CH4) first appeared in the atmosphere Excess of radioactive isotopes such as 14C and 239Pu in rocks and sedimentsarrow_forward

Octane has a density of 703 kg/m3.1 L = 0.2642 gal 1 lb = 453.592 gAn average tree absorbs 48 pounds of CO2 in one year. How many trees would you need to plant to offset the CO2produced from burning one gallon of octane every day for one year (365 days)?arrow_forwardChlor-alkali plants electrolyze NaCl to produce the commodity chemicals caustic soda and chlorine gas. Industrial waste effluent released into waterways from these plants can contain trace amounts of mercury. Legally, the effluent can contain up to 2.50 x 10-9 mol/L of mercury. Determine the minimum volume of water, in megalitres (ML), that must be added to a 1.14 g sample of mercury to dilute the effluent to acceptable levels. Record only your numerical answer with the correct number of significant digits. You do not need to include units as the units appear for you beside the answer box already.arrow_forward

- 3a) The molecule ethyne (or acetylene), which has the molecular formula C₂H₂, contains two carbon atoms with linear geometry. Construct a model of ethyne by first connecting two black balls with three springs. Use two short sticks and two yellow balls to complete the structure. Sketch a perspective representation (a three dimensional drawing) of the structure.arrow_forwardWetlands can play a significant role in removing fertilizer residues from rain runoff and groundwater; one way they do this is through denitrification, which converts nitrate ions to nitrogen gas: 2NO−3(aq)+5CO(g)+2H+(aq)N2(g)+H2O(l)+5CO2(g) Part a. Suppose 285 g of NO3- flows into a swamp each day. What volume of N2 would be produced each day at 17.0°C and 1.00 atm if the denitrification process were complete?____ L of N2 Part b. Suppose 285 g of NO3- flows into a swamp each day. What volume of CO2 would be produced each day at 17.0°C and 1.00 atm? ____ L of CO2 Part c.
