It says that in your molecule, the element in front of the little 2 occur twice. So in CO2, a carbon-atom occurs once, and the oxygen-atom occurs twice.

If you meant to type 2CO + O2 -> 2CO2, then this type of reaction is called synthesis because 2 or more reactants are combining to create one product.
C6H12O6+zymase+yeast---> 2 C2H5OH+2CO2+ENERGY
two carbon atoms and two oxygen atoms present
I believe the balanced chemical equation isC2H5OH+3O2 ---> 2CO2+3H2O the amount of energy relased from the equation is -1409kJ/molhowever I tried to calculate it out myself with a bond energy table i received from my professor and ended up with the number -1283kJ/mol...close enough
how do you draw it.
2 NaHCO3 + H2SO4 --> Na2SO4 + 2CO2 + 2H20
(nh4)2co2
No! Looks like half a combustion reaction and I do not mean the half reaction method. C2H6O + 3O2 -> 2CO2 + 3H2O
Because it will decompose:2[Fe(C2O4)3]3- + γ à 2[Fe(C2O4)2]2- + C2O42- + 2CO2(γ represents a photon)
2c2h5oh + 7o2 --> 2co2 + 3h2o
Four oxygen atoms
