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.
it means there are 2 molecules of O (oxygen) in the compound CO2
The "2" in CO2 indicates that each molecule of carbon dioxide (CO2) contains two oxygen atoms bonded to one carbon atom.
calcium carbonate--> calcium oxide + carbon dioxide CaCO3 (s) --> CaO (s) + CO2 (g) the little letters represent the state symbols, (s) = solid, (g) = gas Its balanced
The balanced chemical equation for the reaction CH4 + 2O2 → CO2 + 2H2O shows that 1 molecule of CH4 reacts with 2 molecules of O2 to produce 1 molecule of CO2 and 2 molecules of H2O. This equation ensures that the number of atoms of each element is the same on both sides of the reaction arrow.

Blood with co2...
I dont know NH4, but CO2 is:1 Ch4 + 2 O2 = 1 CO2 + 2 H2ONH4 + CO2 = CN + 2H2O
Squared
it means there are 2 molecules of O (oxygen) in the compound CO2
You mean balance it? 2C2H6 + 7O2 -> 4CO2 + 6H2O
All guns leak a little bit when you put Co2 in the gun. its normal
This reaction is:2 CO2 = 2 CO + O2
2 Mg + CO2 = 2 MgO + C The reaction is possible only at high temperature.
do u mean CO2?
alcohol, CO2 and 2 ATP
Unbalanced CH4 + O2 = H2O + CO2 Balanced CH4 + 2O2 = 2H20 + CO2
