There Is Concern That the Combustion of Fossil Fuels Like

question 16

Multiple Choice

There is concern that the combustion of fossil fuels like coal and petroleum contributes to climate change by adding carbon dioxide to the atmosphere. Electric cars are being promoted as a way to address this situation by reducing the use of gasoline. Yet most electricity is produced by coal-fired power plants. Several factors need to be considered in determining whether electric cars actually are helpful in this regard. One is the environmental values of these fuels. Estimate the environmental value of coal compared to gasoline from the following information. The environmental value is defined as the amount of energy obtained per mole of carbon dioxide produced, so a larger environmental value is better. Substance
