In the balanced chemical equation, below, determine what the coefficient and the subscript represent in 6H2O.
Choose ALL the answers that are correct.
4 C02 + 6 H20 arrow 2 C2H6+702
In the chemical equation 4 CO2 + 6 H2O arrow 2 C2H6 + 7O2, the coefficient and subscript represent the following:
- The coefficient 6 represents the number of water molecules (H2O) in the equation.
- The subscript 2 represents the number of ethane molecules (C2H6) in the equation.
In the balanced chemical equation, 4 CO2 + 6 H2O arrow 2 C2H6 + 7 O2, the coefficient and the subscript in 6H2O have different meanings.
1. Coefficient: The coefficient represents the number of molecules or formula units of a compound participating in the chemical reaction. In this case, the coefficient 6 in front of H2O indicates that there are 6 molecules of water participating in the reaction.
2. Subscript: The subscript represents the number of atoms of an element within a compound. In this case, the subscript 2 in H2O indicates that there are 2 atoms of hydrogen and 1 atom of oxygen in each water molecule.
Therefore, in 6H2O, the coefficient 6 represents the number of water molecules, and the subscript 2 represents the number of hydrogen atoms within each water molecule.
In the balanced chemical equation 4 CO2 + 6 H2O arrow 2 C2H6 + 7O2, the coefficient and the subscript represent the following:
1. Coefficient (6): The coefficient represents the number of moles or molecules of a compound or element present in the reaction. In this case, it represents the quantity of water (H2O) molecules.
2. Subscript (2): The subscript represents the number of atoms of the element within a molecule. In this case, it represents the number of carbon atoms in the ethane molecule (C2H6).
