What the big in 2CO2 mean?
"CO2" stands for carbon dioxide, which is a chemical compound made up of one carbon atom bonded to two oxygen atoms. The "2" in "2CO2" indicates that there are two molecules of carbon dioxide present.
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?
The balanced equation for the combustion of ethanol (C2H5OH) is: C2H5OH + 3O2 → 2CO2 + 3H2O
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?
The balanced chemical equation for the burning of ethanol (C2H5OH) is: C2H5OH + 3O2 → 2CO2 + 3H2O.
What is the reaction about alcohol lamp?
2c2h5oh + 7o2 --> 2co2 + 3h2o
