You mean balance it?
2C2H6 + 7O2 -> 4CO2 + 6H2O
6c2h6+21o2=12co2+18h2o
The reaction is:CaCO3------------CaO + CO2
Both oxidation and reduction
7/2O2+C2H6->2CO2+3H2O Mole ratio of C2H6:CO2=1:2 No.of mole of CO2=2mol
C8h18
No its a combustion reaction, not a double replacement
6c2h6+21o2=12co2+18h2o
c2h5oh+h2o
2h2s+o2-->2h2o+co2

C3h8 + 5o2 --> 3co2 + 4h2o
NO. There is no chlorine on the reactant side, so it cannot be balanced.
The reaction is:CaCO3------------CaO + CO2
6CO2 + 6H20 +energy yields C6H12O6 + 6O2. This is the equation for photosynthesis.
No because you have an extra H. Sodium hydroxide is NaOH.
Both oxidation and reduction
Na2CO3 + H2SO4 -----> Na2SO4 + H2O + CO2
