How can the carbon dioxide content of the atmosphere hundreds of years ago be determined today and what substances have been blamed for the loss of ozone in the atmosphere?

Solutions

Expert Solution

The concentration of carbon dioxide in the atmosphere hundreds of years ago can be determined by measuring the bubbles of air which have been trapped in the ice sheets of Greenland and antarctic. These evaluations indicate that in the past, the concentration of carbon dioxide in the atmosphere was approximately 270 ppm v. This was long before the emergence of industries which have caused a big variations in the concentration of this gas in the recent past. Low concentration of CO2 several hundred years ago enhanced Antarctic glaciation as well as the evolution of C4 plants. Also, an evaluation of fossil leaves based can be used to evaluate the concentration of carbon dioxide in the past.

The substances that have been blamed for the loss of ozone layer in the atmosphere include Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS). They are made up of combination of chlorine, fluorine, or bromine and carbon.

The amount of carbon dioxide in a gaseous mixture of CO2 and CO can be determined by passing the gas into an aqueous solution that contains an excess of Ba(OH)2, The CO2 reacts, yielding a precipitate of BaCO3, but eh CO does not react. This method was used to analyze the equilibrium compostion of the gas obtained when 1.77 g of CO2 reacted with 2.0 g of graphite in a 1.000 L container at 1100 K. The analysis yielded 3.41...

Public concern about the increase in carbon dioxide (CO2) in the atmosphere has led to numerous proposals to sequester or eliminate CO2. An inventor believes he has developed a new catalyst that can make the following gas phase reaction proceed with 40% conversion of CO2: CO2(g) + H2(g) > H2O(g) + CH4(g) The source of H2 for the reaction would be from the electrolysis of water using electricity generated from solar cells. Assume that 1.5 mole of CO2 enter the...
