6c2h6+21o2=12co2+18h2o
C + h2o = co + h2
You mean balance it? 2C2H6 + 7O2 -> 4CO2 + 6H2O
yes they are balanced
the balanced equation is Na2S2O3 plus H2O2 yields 2NaOH plus H2S2O3 plus O2.
Mg + MgCl2
C2h2+ 2h2 = c2h6
The anwer is 2 (C2H6) + 7(O2) =4 (CO2) + 6 ( H2O) left side : C=4 , H= 12, O=14 right side : C=4 , H= 12, O=14 so they are balanced.
C2H6O + O2 = C2H4O2 + H2O is balanced but not sure if this is what would happen
Me too i don't know
C + h2o = co + h2
No its a combustion reaction, not a double replacement
3H2 + N2 yields 2NH3
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
c2h6 + cl2
You mean balance it? 2C2H6 + 7O2 -> 4CO2 + 6H2O
It is balanced.
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
