can someone help me with carbon dioxide?

non polar  \nit's linear in shape ,so the magnet moment equals zero \nthe lone pairs around the two O atoms \nevery O atom has 2 lone pairs\nthe central atom is C atom

You need to first balance the equation.\n\n2CO + O2 --> 2CO2\n\nUsing this you find the answer to be D.

The reactants I believe are sunlight and carbon dioxide and the products are oxygen and water, I'm not 100% postive.

Sorry freak...not nitrogen...frozen carbon dioxide is commonly referred to as "dry ice". And no way is it water in any sense.\n\nThanks Roscoe.

CO is not a powerful enough reducing agent to reduce CaO.\nPerhaps the questioner meant carbon dioxide?\nIn which case the equilibrium is simple:\n\nCaO + CO2 <-----> CaCO3

There are several theories as to what the best method for dealing with excess carbon dioxide in the atmosphere. The one that I like the best is to turn it into rock. Yes, rock. Ever seen the Grand Canyon? It is made up of carbonate rocks. Through "relatively" simple chemical reactions, scientists can mix carbon dioxide gas with catalysts and form it into rock. Another option is to seed the ocean with powdered iron to stimulate the growth of photosynthetic (use CO2 and give off oxygen)plankton. This is an incredibly powerful method, but is also risky because we don't really understand how this will affect the food chain of the oceans. \nLastly, there is a place in Canada that is pumping carbon dioxide into the chambers left over from oil drilling. The CO2 is compressed into a "supercritical" state, where it behaves like a dense liquid. As a bonus, the CO2 helps to "push out" the oil, making the pumping more efficient. Thousands of tons of carbon dioxide have already been sequestered at just this facility. There are also huge bodies of water underground, where millions of more tons of CO2 can be sequestered.For more info, search for "carbon dioxide sequestration", as that is a common scientinfic term for what you want to do.

Don't listen to the above post. CO2 is not flammable, and you are not necessarily asking for it to be pressurized. The cheapest way to get bottled CO2 is to catch the products of a combustion. I would try to suck the smoke of burning coal into a bottle. Another way is to make your own carbonic acid by blowing air from your lungs into watter. Of course using these cheap methods you'll never get a good sample (eg, humans breathe out about 20% CO2). Perhaps there is a way to get rid of all the gasses?\n\nActually, there are "air sponges" that absorb certain gasses. If you could pump air though enough of these filters to take out all the gasses you don't want, you could be left with pure CO2.

I really don't know and as much as i don't know, i hope this helps.\n\nhttp://physics.nist.gov/PhysRefData/CO2/Html/chap1.html

Argh! I wanted to say H20. But never mind, try CO2 or CaCO3

probably carbon dioxide mostly

96% Carbon Dioxide\n4% Nitrogen\n\n(closer to 3.5% nitrogen with assorted other gasses making up the last 0.5%)

Carbonic acid - H2CO3\n\n:)

Start with the Ca then balance the number of PO4 ions, then balance the Oxygen and the hydrogens should balance themselves out.  Its just trial and error. Monkey with it until it works.

Well, oxygen is used for respiration, and carbon dioxide is only used for photosynthesis. Respiration should occur throughout the day for survival (duh), and photosynthesis can only occur when sunlight is present. So, the ans should be (c)

Simple one will be \nSunlight + Carbon dioxide (CO2) + Water (H2O)--> Glucose (C6H12O6) + Oxygen (O2).\nor \n6CO2 +12 H2O (light energy and chlorophyll) ---> C6H12O6 + 6O2\nRemember to use subscript whenever necessary.

CO2 is carried through the blood in the body to the lungs to be exhalated.
