An engine emits about 5lbs of Carbon atoms in the form of Carbon dioxoide molecules for every gallon of gas it consumes. The average American car is driven about 12,000 miles per year. Using this information, check the statement that the average American car releases its own weight in carbon into the atmosphere each year. What are some assumptions that you can make to solve this problem?
For every 5lb of the car's weight = 1 gallon of gas
the average weight of a car = 4000lbs
the average miles per gallon = 23.6
With this information, you can use conversions to determine how many gallons of gas that car requires to go 12000 miles.
As of the writing of this text, EPA standards limit atmospheric ozone levels in urban environments to 84 ppb. How many moles of ozone would there be in the air above Los Angeles County (an area about 4000 square miles; consider a height of 100 m above the ground) if ozone was at this concentration?

Photochemical smog is a type of air pollution in the troposphere of our planet produced when sunlight acts upon motor vehicle exhaust gases to form harmful substances such as ozone (O3). For example, nitrogen dioxide (NO2) reacts with atmospheric oxygen (O2) in the presence of light to produce ozone (O3) and nitrogen monoxide (NO).arrow_forwardWhat emissions from human activities lead to ozone depletion?

- 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_forward4.
