Question

this model shows the process of photosynthesis. the law of conservation of mass reminds us that matter is neither created nor destroyed, so the atoms present in the reactants of photosynthesis are still present in the products of photosynthesis. which of these equations accurately portrays this fact? a co2 + h2o+ light energy → c6h12o6 + o2 b 6co2 + 6h2o+ light energy → c6h12o6 + 6o2 c 6o2 + 6h2o+ light energy → c6h12o6 + 6co2 d 6co2 + 6h2o+ light energy → 6c6h12o6 + 6o2

Explanation:

Step1: Recall photosynthesis equation

Photosynthesis uses carbon - dioxide ($CO_2$), water ($H_2O$) and light energy to produce glucose ($C_6H_{12}O_6$) and oxygen ($O_2$).

Step2: Balance the equation

The balanced chemical equation for photosynthesis is $6CO_2 + 6H_2O+\text{light energy}
ightarrow C_6H_{12}O_6 + 6O_2$. This ensures the law of conservation of mass as the number of atoms of each element is the same on both sides of the equation.

Answer:

B. $6CO_2 + 6H_2O+\text{light energy}
ightarrow C_6H_{12}O_6 + 6O_2$
