Data taken over time reveal an increase in CO2 in the atmosphere. The large increase in the combustion of hydrocarbons since the Industrial Revolution is often cited as a reason for the increasing levels of CO2. However, an increase in water vapor has not been observed during the same period. Remembering the general equation for the combustion of a hydrocarbon, does the difference in these two trends disprove any connection between human activities and global warming? Explain your reasoning.
Please note that NO3 has an odd number of electrons. But you must decide where the missing electron will be. Does the central atom violate the octet rule or do the oxygen atoms? Use formal charges to decide.
