DedPeter [7]

The balanced equation

6CO₂ + 6H₂O = C₆H₁₂O₁₆ + O₂

<h3>Further explanation</h3>

Given

Reaction

CO2 + _H2O = _C6H12O16 + _O2

Required

Balanced equation

Solution

Give a coefficient

aCO₂ + bH₂O = C₆H₁₂O₁₆ + cO₂

Make an equation

C, left = a, right = 6⇒a=6

H, left = 2b, right = 12⇒2b=12⇒b=6

O, left=2a+b, right = 16+2c⇒2a+b=16+2c⇒2.6+6=16+2c⇒2c=2⇒c=1

The equation becomes :

<em>6CO₂ + 6H₂O = C₆H₁₂O₁₆ + O₂</em>
