# What is the chemical reaction for photosynthesis?

$6 C {O}_{2} + 6 {H}_{2} O + h \nu \rightarrow {C}_{6} {H}_{12} {O}_{6} + 6 {O}_{2}$
So is mass balanced; is charge balanced? You must learn to look at chemical reactions to see that they are indeed stoichiometrically balanced. If they are unbalanced, they cannot be accepted as a model for chemical reactivity. What does the $h \nu$ term mean in the reaction?
