Question: Carbon Dioxide? What atoms form carbon dioxide? Thanks for the help.

Answer: Carbon and oxygen. Carbon dioxide = CO(2)

Question: How does carbon dioxide affect our atmosphere? Doesn't carbon dioxide warm the atmosphere? Without carbon dioxide and other greenhouse gases, the atmosphere would be much colder than it is now, right?

Answer: Yes. Carbon Dioxide traps solar radiation. Without a little of it, the Earth would be too cold for habitation. Too much, and it gets too hot.

Question: How does oxygen change to carbon dioxide in the blood? When oxygen is breathed in and carbon dioxide is breathed out, how is the oxygen changed to carbon dioxide? Or where does the carbon dioxide come from?

Answer: You breathe in oxygen, which your blood delivers to your cells so necessary chemical reactions can occur. Your cells then dump waste from the chemical reaction as carbon dioxide into your blood, which you breathe out.

Question: How do you know when carbon dioxide is produced in a chemical reaction? I did a science experiment (chalk and hydrochloric acid), and it bubbled and carbon dioxide was produced (the teacher said it was carbon dioxide) but I have to do a science experiment and I have to say HOW I know that CARBON DIOXIDE was produced. I have no idea, because she never explained how to tell what was produced. Please help! Thank you! Thank you!

Answer: There are many test 1. YOu will hear hissing sound on evolution of carbon dioxide with brisk effervescence (bubbling) in the test tube. 2. you can pass the gas evolved through freshly prepared lime water. if it is carbon dioxide then it will turn milky because of formation of insoluble calcium carbonate. Ca(OH)2 + CO2 -------> CaCO3 + H20 3. if you keep a moist blue limtus paper over the test tube, it will turn red as carbon dioxide is acidic in nature.

Question: How can carbon dioxide be trapped into a dead body? I'm doing a carbon cycle project and in my project someone dies from carbon dioxide poisoning and then is cremated. So I'm trying to figure out where the carbon would go and my teacher would only give me a couple hints; carbon dioxide can not burn and something about it being trapped in the body. So if you could just tell me how it could be trapped then I think I can figure out the rest. Thanks!

Answer: I'm not too sure, but this is my best educated guess: Once dead, all activity in your body stops. So bacteria in your gut and chest cavity produce enough gas (methane, hydrogen sulfide and CARBON DIOXIDE) that make a dead body "bloat". Hope that helps!

Question: How to measure carbon dioxide? and what plant absorbs the most carbon dioxide? Besides using a Fyrite device, is there any way to measure carbon dioxide levels? If using a Fyrite device is the only way to do this, what's the basic idea behind how they work? And...do you know which types of plants absorb the most carbon dioxide, or photosynthesizes the most efficiently? Thanks!

Answer: One method is a gas train of flasks. One flask contains an aqueous solution of sodium hydroxide of a known concentration. Air is bubbled through the sodium hydroxide for a given amount of time. The concentration of the sodium hydroxide is determined by tritration. The data is inserted into a formula and the result is the amount of carbon dioxide present in the air. I don't have the reference books available to be more specific. Plants that are highly efficient photosynthesizers are the C-4 plants such as sugar cane and corn so they would likely be most efficient absorbing carbon dioxide.

Question: What effect would increased carbon dioxide have on plants? One of the most dramatic environment changes today is the increase in carbon-dioxide levels in the atmosphere. We usually hear about it in connection with global warming, but that's not the only issue. What effect would increased carbon dioxide have on plants? If more trees are planted, would this stand to have any effect atmospheric levels?

Answer: Just a guess, but I would say they could grow larger, faster, quicker, etc. Plants take in carbon-dioxide and release oxygen.

Question: How many pounds of carbon dioxide would be formed when burning one pound of carbon? Carbon has an atomic weight of 12. Oxygen has an atomic weight of 16. When an atom of carbon (weighing 12 atomic units) combines with two atoms of oxygen (each weighing 16 atomic units), as in C + O2 = CO2 the carbon dioxide that forms weighs 44 atomic units. When 12 pounds of carbon burns, it combines with 32 pounds of oxygen to form 44 pounds of carbon dioxide. How many pounds of carbon dioxide would be formed from burning one pound of carbon?

Answer: You got all the data already... 44/12 = 3.666667 lb

Question: How is carbon dioxide level increased in commercial glasshouse production? In commercial glasshouse production, the level of carbon dioxide is elevated to increase production. How could this be done?

Answer: I am not familiar with the term glass house. But if you are referring to greenhouses, CO2 gas from tanks is pumped into the greenhouse to elevate the ambient level. This can increase photosynthesis under certain conditions (enough light, nutrients etc) to a certain extent. It is relative to the organisms involved.

Question: How does the carbon from carbon dioxide in the atmosphere get into the human body? We do not breath carbon dioxide so it is an unacceptable answer, that is rather a waste product. If anyone can offer a more in detail answer such as the processes which occur for the carbon to end up in the human body, that would be great and much thanks in advance!!!

Answer: Carbon based compounds predominate in the moist parts of human and animal bodies, but this carbon does not get in through respiration. We eat carbon compounds in the form of animal and plant materials. The respiratory system breathes in oxygen and breathes out carbon dioxide, along with numerous other gasses. All of the above is very simplified. Take the course in vertebrate physiology.

Question: How much carbon dioxide is released into the atmosphere when you open a can of Coke ? Then, what is the annual global amount of carbon dioxide released from fizzy drinks ? Are fizzy drinks bad for the planet or an ideal way to cool down as the planet gets hotter ?

Answer: Doing an experiment measuring the decrease in the mass of a 500ml coke bottle when you open it (being very careful to not allow any spray of the liquid itself) I reckon on about 2.5g of carbon dioxide in that volume. Some is left dissolved in the liquid, and some is bound up as carbonic acid (a weak acid produced by dissolving carbon dioxide in water). So I'd guess around 5g per half litre, or 10g per litre. That makes it 10x less polluting than driving one kilometre in a Prius or 20x less than an SUV :) So it's not that bad for the planet - there are more important factors!

Question: How did carbon dioxide, water, and nitrogen change during the first periods of Earth? How did the following gases (Carbon dioxide, Water, Nitrogen) change during these times: 1. The Early Earth had no atmosphere or ocean. 2. Then volcanic gases and comets vaporizing on impact with the Earth released gases that became the atmosphere. 3. Originally, the atmosphere was hot and all water was in the form of water vapor. 4. Then, as the Earth cooled, water vapor condensed and fell as rain, covering the Earth in one big ocean until continents formed.

Answer: then there was the first ice age because earth couldnt get exposed to sun. after another million years or so when earth started to get exposed to sun because the dust and smoke and vapours cleared, the ice slowly started to melt. but during that time for the first time there was chemical reaction so hydrozen started to get separated fro oxyzen. so the oxygen was released in the atmosphere.

Question: How much carbon dioxide is emitted into the air by a car in one gallon? Basically i just want to know how much carbon dioxide is spewed into the air after one gallon.

Answer: A gallon of gasoline weighs 6.15 pounds, and the chemical formula is approximately C8H18. If you burn that gasoline completely, you end up with 18.97 pounds of carbon dioxide - 1158 gallons, once it cools down to 70F.

Question: How much carbon dioxide in kilograms is produced upon the complete combustion of 26.9 of propane? Assume that the density of the liquid propane in the tank is 0.621 g/ mL This is a stoich question that I just dont understand! It says to start out by balancing the equation. How do I know what the reaction is between propane and carbon dioxide to even balance the equation & then move on to finding this answer? Please help me. Thank you so much! I really appreciate it!

Answer: just to let you know, the units of the "26.9" didn't come through so you will end up with choices 1 C3H8 & O2 --> 3CO2 & water 1 mole of C3H8 has a mass of 44.10g/mol , and produces 3 moles of CO2 @ 44.01 g/mol = 132.03 grams assuming that you had 26.9 ml of propane: 26.9 ml @ 0.621 g/mol = 16.70 grams of propane 16.70 grams of propane @ 132.03 g CO2 / 44.01 g propane = your first choice 50.1 grams of CO2 aka 0.0501 kg of CO2 assuming that you had 26.9 litres of propane: your 2nd choice 50.1 kilograms of CO2 assuming that you had 26.9 m3 of propane: your 3rd choice 5.01 X10^4 kilograms of CO2 last choice , email me

Question: How does carbon dioxide become trapped in soda to begin with? When fizzing occurs when opening soda, this is carbon dioxide being released from the liguid. But, how does it get their in the first place?

Answer: The carbonation goes into the soda under a higher pressure than you get @ or above sea level. That's why, when you open the bottle, it releases the pressure, and some of the bicarbonate comes out of solution. If you have ever noticed, your Coke is more likely to 'boil over' when you are at a higher elevation. If you opened one while you were is a hyperbaric chamber under pressure, your drink would probably not fizz at all.
