TOPIC: Global warming is one of the most serious environmental problems today as it is caused primarily by the burning of fossil fuels (emissions) and deforestation.
With the possible exception of another world war, a giant asteroid, or an incurable plague, global warming may be the single largest threat to our planet. For decades human factories and cars have spewed billions of tons of greenhouse gases into the atmosphere, and the climate has begun to show some signs of warming. Many see this as a harbinger of what is to come. If we don't curb our greenhouse gas emissions, then low-lying nations could be awash in seawater, rain and drought patterns across the world could change, hurricanes could become more frequent, and El Niños could become more intense. On the other hand, there are those, some of whom are scientists, who believe that global warming will result in little more than warmer winters and increased plant growth. In truth, the future probably fits somewhere between these two scenarios.
Describe in detail how global warming is effecting our temperature, ecosystems, health, our climate and future. Find out when this started happening and how global warming is accelerating. Find out about the rate of the polar ice caps melting. Discuss why politicians say this is not harmful. Discuss the concern of the global community. What is on the horizon to solve this problem?
Calculate the wavelength, in nanometers, of the spectral line produced when an electron in a hydrogen atom undergoes the transition from the energy level n = 7 to the level n = 2.
For every molecule of PM that is produced, one molecule of acrolein is formed. If acrolein is not used to cure cancer, what might happen to the acrolein?
What are the rules for when the molecule goes through the chloronium ion or not. For example a cyclopentane with a double bond. One of the double bonded carbons is bonded to a methyl group.
How many times faster will the reaction occur at 43^circ {rm C} than at 0 ^circ {rm C}? How many times faster will the reaction occur at 43^circ {rm C} than at 0 ^circ {rm C}?
A 0.831-g sample of SO3 is placed in a 1.00-L container and heated to 1100 K. The SO3 decomposes to SO2 and O2: 2SO3(g) 2SO2(g) + O2(g). At equilibrium the total pressure in the container is 1.300 atm. Calculate Kp for the above reaction at 1100..
