Answer:

Explanation:

Since the equation is not given, let us write and balance it:

Reactants: Carbon dioxide (CO₂)

Water(H₂O)

Products: Glucose(C₆H₁₂O₆)

Oxygen(O₂)

The reaction equation is shown below:

CO₂ + H₂O → C₆H₁₂O₆ + O₂

But the equation is not balanced:

to balance the equation

aCO₂ + bH₂O → cC₆H₁₂O₆ + dO₂

for C:

a = 6c, if c = 1 then a = 6

for O:

2a + b = 6c + 2d

for H:

2b = 12c, since c = 1, b = 6

In 2a + b = 6c + 2d, solving for d:

2(6) + 6 = 6(1) + 2d

18 = 6 + 2d

d = 6

Therefore, the balanced equation is:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
