Question
Chapter 20, Problem 55SCQ
Interpretation Introduction
Interpretation: The sources of given pollutants should be given.
Concept introduction:
Heavy metals: Elements having high atomic weight and the density will be multiple times that of water. The increase in concentration of these metals will lead to severe environmental problems.
Arsenic, chromium, mercury and lead are the top toxic metals known. They are considered to be carcinogens too.
The presence of heavy metals in the environment is due to industrial, agricultural, atmospheric and pharmaceutical sources.

Carbon dioxide emissions associated with a one-night stay in a hotel room are calculated at 29.53 kg of CO2 per room day for an average hotel. The 200 rooms of your hotel are all occupied for two days during a college football game. How much CO2 did the guests and hotel release into the atmosphere?
Why are human activities that release carbon dioxide into the atmosphere causing concern?
The U.S. is one of several countries committed to reaching “net-zero” carbon emissions by 2050. This means that by 2050, all carbon dioxide emissions must be matched by the amount of carbon dioxide removed from the air. Why is it essential for all countries in the world to meet carbon reduction commitments like this

- 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.arrow_forward2: Write all the chemical reactions involved in the thinning of ozone layer from the reaction between chlorofluorocarbon (CFC) and ozone layer(O3).arrow_forwardQuestion 6 Examine the graph below, which shows global emissions of ozone-depleting sub- stances from 1961 to 2014.
