(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.

- 2.) It’s a bad day in the lab! Two students are doing experiments. Each is 20 feet away from the professor. At the same time, each of them lets the same amount of a smelly gas into the room. One of them releases ammonia, NH3, and the other releases SO2. NH3 has a pungent odor, and SO2 smells like rotten eggs. The professor has no idea that this has happened, until she smell the first gas. Which chemical will the professor smell first? (NH3 or SO2) . If the professor starts to smell the first gas 42. seconds after the gas is released, how long will it take her to smell the second gas? sec. * Note: It is unsafe practice to work with these chemicals in an open lab.arrow_forwardGiven these two statements, which can be concluded? (1) Apart from adverse environmental effects, toxic air pollution can lead to serious health problems. (2) Reducing air pollution contributes to birth defects, genetic mutations, and cancer. Both statements are incorrect. Only statement 1 is correct. Both statements are correct. Only statement 2 is correct.arrow_forwardThe amount of anthropogenic SO2 emission from Pakistan was 180 kilo tonnes(kt) in 20191.How many grams of SO2 were emitted to the atmosphere?How many grams of Sulfur was emitted to the Atmosphere?Pakistan population was 216.6 million in 2019.

- Some greenhouse gases, such as fluorocarbons (CFCs, HFCs, PFCs, etc.), are human-made. Others, such as water, methane, and carbon dioxide, are naturally produced. Which type of greenhouse gas (human-made or natural) is more difficult to control and eliminate? Which types are easier? In three to five sentences, provide evidence for your argument.arrow_forward(a) What is the difference between chlorofluorocarbonsand hydrofluorocarbons?
