Answer:Chemical equation(balanced):

 6 Co2 + 6 H2O→ C6H12O6 + 6 O2

Word equation:

6 carbon dioxide molecule + 6 Water molecules → glucose + 6 oxygen molecules

Explanation:

6 (atomic number) Carbon dioxide  will split into

6 (atomic number)Carbon and 12 (atomic number) oxygen molecules

and water will divide into 12 (atomic number) hydrogen and

6 (atomic number) oxygen molecules.

now the 6 (atomic number) carbon molecules bond with

12 (atomic number) hydrogen molecules and

also with 6 (atomic number) oxygen molecules.

Now the rest 12 (atomic number oxygen molecules

form into 6 O2.
