Assuming you mean 2FeO3+3C ---> 4Fe+3CO2, yes, it is balanced.
CH4 + 2O2 --> CO2 + 2(H2O), the products are CO2 and H2O
this is an exotermic reaction
3H2C2O4 + 2K2MnO4 = 6CO2 + 2K2O + Mn2O3 + 3H2O
your equation is wrong. it should be c6h12o6 + 6 o2 --> 6 co2 + 6h2o The products contain 18 oxygen atoms (so do the reactants)
Propane is burned to provide the heat in many cooking grills. The chemical reaction for this process is shown in the equation below. C3H8 + 5O2 ? 3 CO2 + 4H2O + energy What are the products in this chemical reaction? 3CO2 + 4H2O + energy
It is balanced.
2
Yes. Except that the word is equals, not eqauls.
6c2h6+21o2=12co2+18h2o
Yes
The balanced equation is: CH4 + 2 O2 → CO2 + 2 H2O
CO2 is not an equation, so it cannot be balanced. It is a chemical formula.
C5h8 + 7o2 -> 5co2 + 4h2o
C5h8 + 7o2 --> 5co2 + 4h2o
NO. There is no chlorine on the reactant side, so it cannot be balanced.
6CO2 + 6H20 +energy yields C6H12O6 + 6O2. This is the equation for photosynthesis.
2C3H4O7 + O2 -> 6CO2 + 4H2O
