Answer: A. yes, the equation is balanced.
B. C₆H₁₂O₆ + 6 O₂ → 6 H₂O + 6 CO₂
Explanation:
A.
The chemical equation of photosynthesis is given by:
6 H₂O + 6 CO₂ → C₆H₁₂O₆ + 6 O₂
where in carbon dioxide along with the water in the presence of sunlight and chlorophyll react to form sugar and liberate oxygen.
The given chemical equation is balanced as there are equal number of atoms of each element on reactant side and product side.
There are 12 Hydrogen atoms, 18 Oxygen atoms and 6 Carbon atoms on each side.
B. The chemical equation for cellular respiration is just opposite to the chemical equation of photosynthesis. The products become reactants and reactants become products. Thus, the balanced chemical equation of cellular respiration is:
C₆H₁₂O₆ + 6 O₂ → 6 H₂O + 6 CO₂
