O=O refers to an O2 molecule; 2 oxygen atoms double-bound together. It's the oxygen we breath.
Written like this: O=C=O
it might be intended as a crude representation of carbon dioxide.
The level of carbon dioxide in the air.
I assume you mean CH2=C=CH2 or 1,2-propadiene. The molecule has two equally electronegative substituents attached to the central carbon, so no it is not polar. If it was CH2=C=O, then yes it would be polar, because the oxygen atom pulling the electron cloud toward itself, thus making it slightly negative which make he molecule polar.
The structural formula for carbon dioxide is O=C=O, where the carbon atom is double-bonded to two oxygen atoms.
C + O ==> COKeq = [CO]/[C][O]
A C-O bond is slightly shorter than a C-C bond (143 pm vs. 154 pm respectively for single bonds).For double bonds the trend is the same, with C=O bond being 121 pm, and a C=C bond being 134 pm.See the Web Links to the left for the source.
If you mean 3c = 214, then c = 68

O is Oxygen C is Carbon N is Nitrogen H is Hydogen Is that what you mean?
Synthesis E + C > C E + E > C
2+21=23 or 3+15=18 ok . ans:h-c-d-d-g-g 45+585*=474 552++
The "c" in E=mc2 stands for the speed of light, which is approximately 299,792 kilometers per second. This equation, proposed by Albert Einstein in his theory of special relativity, relates energy (E) to mass (m) and the speed of light (c).
Are you sure about the letter "o"? 60 equals seconds in a minute and minutes in an hour.
c is any constant value
0 Degrees Centigrade/Celsius equals 32 Degrees Fahrenheit
b divided by 2
if you mean 6-5c=-29:c=7
