Explain why burning biodiesel fuel has a differen impact pn atmospheric CO2 concentrations than does burning fossil fuels?

∙ 12y ago
Biodiesel contains carbon that was recently present in the atmosphere rather than fossil-fuel
carbon that was in the atmosphere long ago and has been sequestered beneath Earth's surface.
Hence the burning of biodiesel does not contribute to a net increase in the amount of carbon
dioxide currently circulating in the atmosphere, whereas the burning of fossil fuel does contribute
to a net increase in the concentration of carbon dioxide in the atmosphere.

If you performed a melting point experiment in the laboratory and on the top of the mountain would your results differ explain?
Yes because the atmospheric pressure at mountain is lower, therefore m.p becomes lower
How does the kinetic-molecular theory explain why atmospheric pressure is greater at lower altitudes than at higher altitudes?
The kinetic-molecular theory explains that there is more pressure at lower altitudes because there are more obstacles for the gas molecules to run into and create more pressure. They collide with the walls of their container as well as other molecules. And at higher altitudes, there is more space for the gas molecules to travel and not bump into things therefore not as much pressure is created. Also, some extra info: the atmosphere is denser closer to the Earth's surface because the weight of atmospheric gases at any elevation compresses the gases below.
What do plate tectonics help explain?
They explain the cause of earthquakes on Earth.
Explain meaning of annual range of temperature?
explain the temperature annual range
Explain why a helium weather balloon expands as it rises in the air Assume that the temperature remains constant?
When the helium balloon starts gaining height, the pressure decreases and as the gas molecules are very freely movable (higher than the normal). They move apart from each other in the mean while they make the balloon to expand. The decrease in atmospheric pressure relative to pressure inside the balloon causes it to expand.
Which is not a process that has been proposed to explain the formation of precipitation?
the atmospheric subduction process
Ash and carbon dioxide coming from the volcano contributes to atmospheric cooling, True or false?
False
State and explain how the boiling point of water will change if the atmospheric pressure falls?
Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
Use trade winds in a sentence?
explain how atmospheric pressure over the pacific ocean might affect how trade winds blow.
Which atmospheric gases do photosynthesis and cellular respiration help keep constant?
explain how photosynthesis maintain the composition of air?
Explain the functional importance of the partial vacuum that exists in the intrapleural space?
If not present (and the intra-alveolar pressure equaled atmospheric pressure) the lungs would collapse.
Pros and cons of using biodiesel?
Biodiesel has been controversial. I've include 4 links that explain the issues with biodiesel and biofuels in general. First, the pros 1. It works. A mix of diesel and biodiesel may be necessary on some cars. It can be used in buses and trains. Use of biodiesel has been increasing. 2. We have a limited supply of fossil fuels. The ability to "grow our energy" extends the lifetime of our natural resources. 3. Biodiesel burns cleaner than regular diesel, based on particulates from tail-pipe emissions (see wikipedia link on environmental problems). 4. We must import oil, and this creates a dependence on other countries. It would be devastating to our economy if any country cut us off from this supply. So, biodiesel adds to our energy security. 5. Adding to the supply of fuels should help moderate prices of these fuels by making them less scarce commodities. 6. Biodiesel is good for farmers around the world. It is an additional crop they can grow. Now, the cons, 1. Converting crops into biofuels will mean that less of there will be less available produce to feed people. This drives up the price of food. One crop in particular is soybeans, which is used as animal feedstock. So as soybeans become more valuable to make fuels, meat prices will increase. 2. Biodiesel (or more generally biofuels) means that there will be extensive deforestation in tropical areas such as the Amazon rainforest to grow sugar cane and soybeans for biofuels. This will have a large impact on environment and CO2 emissions. CO2 pollution is linked to global warming. Thus some environmentalists are calling biodiesel a worse alternative than natural diesel. 3. The increase in palm oil farms in Asia has lead to use of pesticides and contamination of drinking water supplies. (see wikipedia link) 4. Biodiesel is not a cleaner fuel to burn. It produces 10% more nitrogen oxide tail pipe emissions than diesel. (see Wikipedia link on environmental issues). 5. Promoters of biofuels have created a false impression of an easy solution to energy needs. Due to all the problems they cause, these fuels can not satisfy our needs. I suggest that you read through the links provided. Perhaps there are more pros and cons. Certainly, the question of whether biodiesel burns cleaner is a difficult one. Good luck! :) Biodiesel is less pollutive. It is safer to handle :( It is more expensive at the moment Not approved by all auto dealers
What is a METEORTOlogist?
A meteorologist is an individual with specialized education who uses scientific principles to explain, understand, observe or forecast the earth's atmospheric phenomena (such as weather) and/or how the atmosphere affects the earth and life on the planet.
If you performed a melting point experiment in the laboratory and on the top of the mountain would your results differ explain?
Yes because the atmospheric pressure at mountain is lower, therefore m.p becomes lower
If you boil water at the top of a mountain would you expect it to boil at 100 degree Celsius explain?
Yes. In general, higher altitudes mean lower atmospheric pressure. Lower atmospheric pressure means lower boiling points.
How you will you explain pressure belts and winds diagram?
The Coriolis effect explains this phenomenon clearly. Pressure belts and wind belts differ in patterns depending on certain atmospheric factors like temperature.
Can you explain the procedure used to find the rate law?
Basically, you compare two initial concentrations of the reactants. Initially you start off with the variables x and y. To find x, you take a set of concentrations where the base of y's that are being compared are the same. That way, everything cancels out just leaving the x to solve. Then the same process can be done to solve y. Then there you have it. RATE LAW!
