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.

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.
Blood with co2...
I dont know NH4, but CO2 is:1 Ch4 + 2 O2 = 1 CO2 + 2 H2ONH4 + CO2 = CN + 2H2O
it means there are 2 molecules of O (oxygen) in the compound CO2
The balanced chemical equation for that reaction is: C2H6 + 7/2 O2 -> 2 CO2 + 3 H2O
Squared
All guns leak a little bit when you put Co2 in the gun. its normal
This reaction is:2 CO2 = 2 CO + O2
The balanced chemical equation for the reaction between magnesium (Mg) and carbon dioxide (CO2) is: 2 Mg + CO2 -> 2 MgO + C
The balanced equation for methane burning in oxygen to form water and carbon dioxide is: CH4 + 2O2 -> 2H2O + CO2
alcohol, CO2 and 2 ATP
The "2" in CO2 indicates that each molecule of carbon dioxide (CO2) contains two oxygen atoms bonded to one carbon atom.
