What is a balanced chemical equation for the formation of glucose by photosynthesis

6CO₂ + 6H₂O + light energy => 6O₂ + C₆H₁₂O₆

Explanation:

Start with the skeleton equation:

CO₂ + H₂O + light energy => O₂ + C₆H₁₂O₆

If you forget, think about what a plant needs to survive: water and air, except they use our "waste" air, carbon dioxide. Trees make oxygen, as do other plants. Plants make their own food, glucose.

Count the number of atoms in the skeleton equation

CO₂ + H₂O + light => O₂ + C₆H₁₂O₆

Reactants                                       Products

C 1                                                    C 6

H 2                                                   H 12

O 3                                                   O 8

It is obvious we need to add a few coefficients to the reactant side because there are significantly fewer atoms. This becomes more of a trial and error process. Remember to keep track of the atoms each time you change coefficients.

I would start by making the carbon and hydrogen atoms even.

6CO₂ + 6H₂O + light => O₂ + C₆H₁₂O₆

Reactants                                       Products

C 6                                                    C 6

H 12                                                   H 12

O 18                                                   O 8

Now there are not enough oxygen atoms in the products. Change the coefficient in the diatomic O2 instead of glucose because the other elements are balanced.

6CO₂ + 6H₂O + light=> 6O₂ + C₆H₁₂O₆

Reactants                                       Products

C 6                                                    C 6

H 12                                                   H 12

O 18                                                   O 18

Since the number of each atom in the reactants and products are even, the balanced chemical equation for photosynthesis is:

6CO₂ + 6H₂O + light energy => 6O₂ + C₆H₁₂O₆

cell regulation is conducted by special proteins.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
