Answer:
To determine if the given chemical equation is carbon balanced, we need to count the number of carbon atoms in the reactants and compare it to the number of carbon atoms in the products.
Reactants:
2 C2H6 -> 4 carbon atoms
Products:
4 CO2 -> 4 carbon atoms
Since the number of carbon atoms on the reactant side is equal to the number of carbon atoms on the product side, we can conclude that the given chemical equation is carbon balanced.
