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.
What else can I help you with?
What does the big 2 mean in 2co2?
nnkn
What the big in 2CO2 mean?
'Big what???' 2CO2 The prefix '2' means two molar ratios. The 'C' is one atom of carbon The 'O' is oxxygen The suffix '2' , which should be written subscript, indicates that there are two atoms of oxygen.
What half reaction is 2co o2 - 2co2?
The half reaction for the given chemical equation 2CO + O2 -> 2CO2 is: 2CO -> 2CO2 (in acidic medium) 2CO -> 2CO2 + 2H2O + 2e- (in basic medium)
How many oxygen atoms are there in the formula 2CO2?
There are 4 oxygen atoms in the formula 2CO2. Each CO2 molecule contains 2 oxygen atoms, so when you have 2 CO2 molecules, you get a total of 4 oxygen atoms.
What are the reactants of alcoholic fermentation?
C6H12O6+zymase+yeast---> 2 C2H5OH+2CO2+ENERGY
What is the chemical equation combustion of ethanol?
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
What are the stoichiometric coefficients for the combustion of ethanol?
The balanced chemical equation for the combustion of ethanol is C2H5OH + 3O2 -> 2CO2 + 3H2O. Therefore, the stoichiometric coefficients are 1 for ethanol, 3 for oxygen, 2 for carbon dioxide, and 3 for water.
The coefficient in 2 in 2CO2 means that there are?
two carbon atoms and two oxygen atoms present
Balanced equation for the combustion of ch3ch2oh plus o2--co2 plus H2O?
CH3CH2OH + 3O2 --> 2CO2 + 3H2O Reactants: 6 H; 2 C; 7 O. Products: 6 H; 2 C; 7 O
Write a balanced symbol equation for the complete combustion of ethanol?
It is: C2H5OH+3O2 ----> 2CO2+3H2O
What is the balanced chemical equation for the burning of ethanol?
C2H5OH +3O2 gives 2CO2 +3H2O ...it burns with ablue flame in air
What is the reaction about alcohol lamp?
2c2h5oh + 7o2 --> 2co2 + 3h2o
