Choose ALL the answers that are correct.
4CO2 + 6H2O → 2 C2H6 + 7O2
A. The 2 subscript represents 2 water molecules.
B. The 6 coefficient represents 6 molecules of water.
C. The 2 subscript represents 2 atoms in each water molecule.
D. The 6 coefficient represents 6 atoms in each water molecule.
A. The 2 subscript represents 2 water molecules.
B. The 6 coefficient represents 6 molecules of water.
B. The 6 coefficient represents 6 molecules of water.
C. The 2 subscript represents 2 atoms in each water molecule.
The correct answers are:
A. The 2 subscript represents 2 water molecules.
C. The 2 subscript represents 2 atoms in each water molecule.
In the given balanced chemical equation, 6H2O represents 6 molecules of water. The coefficient 6 in front of H2O indicates that there are 6 molecules of water involved in the reaction.
The subscript 2 in H2O represents the number of atoms present in each water molecule. Since water (H2O) is composed of 2 hydrogen atoms (H) and 1 oxygen atom (O), the subscript 2 means that there are 2 hydrogen atoms and 1 oxygen atom in each water molecule.
