Question

what is the chemical equation for photosynthesis? choose the best answer
6 co2 + 6 h2o --> c6h12o6 + 6 o2
co2 + h2o --> c6h12o6 + o2
c6h12o6 + o2 -> co2 + h2o
c6h12o6 + 6 o2 -> 6 co2 + 6 h2o

Explanation:

Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide ($\ce{CO2}$) and water ($\ce{H2O}$) into glucose ($\ce{C6H12O6}$) and oxygen ($\ce{O2}$) in the presence of sunlight. The balanced chemical equation for photosynthesis is $6\ce{CO2}+6\ce{H2O}\to\ce{C6H12O6}+6\ce{O2}$. The second option is unbalanced. The third and fourth options represent the reverse process (cellular respiration).

Answer:

$6\ce{CO2}+6\ce{H2O}\to\ce{C6H12O6}+6\ce{O2}$ (the first option)
