In the balanced chemical equation, the term 6H2O indicates the presence of water molecules, where "H2O" represents the chemical formula for water.
Let's analyze the options:
a. The 2 subscript represents 2 atoms in each water molecule.
Correct. This is true because the subscript "2" in H2O indicates that there are 2 hydrogen atoms in each water molecule.
b. The 6 coefficient represents 6 atoms in each water molecule.
Incorrect. The coefficient "6" does not represent the number of atoms in each molecule; instead, it represents how many molecules of water are present.
c. The 6 coefficient represents 6 molecules of water.
Correct. This is true, as the coefficient "6" indicates that there are 6 water molecules.
d. The 2 subscript represents 2 water molecules.
Incorrect. The subscript "2" refers to the number of hydrogen atoms in each H2O molecule, not the number of water molecules.
Therefore, the correct answers are:
- a
- c
