Question

for this item, drag the answers into the appropriate boxes. q: scientists used energy for the process. the reactions that take place in the chloroplasts to transform light energy into chemical energy are summarized in a chemical equation. drag each molecule into the correct position in the chemical equation. c₆h₁₂o₆, 6h₂o, 6o₂, 6co₂

Explanation:

The process described is photosynthesis, where light energy is used to convert carbon dioxide ($\ce{CO_2}$) and water ($\ce{H_2O}$) into glucose ($\ce{C_6H_{12}O_6}$) and oxygen ($\ce{O_2}$). The balanced chemical equation for photosynthesis is:

Step 1: Identify reactants and products

Reactants (left side): Carbon dioxide ($\ce{6CO_2}$) and water ($\ce{6H_2O}$)
Products (right side): Glucose ($\ce{C_6H_{12}O_6}$) and oxygen ($\ce{6O_2}$)

Step 2: Write the equation

The unbalanced equation is:
$\ce{CO_2 + H_2O ->[light][chlorophyll] C_6H_{12}O_6 + O_2}$

Step 3: Balance the equation

To balance carbon, we need 6 $\ce{CO_2}$:
$\ce{6CO_2 + H_2O ->[light][chlorophyll] C_6H_{12}O_6 + O_2}$

To balance hydrogen, we need 6 $\ce{H_2O}$ (since 6×2=12 H):
$\ce{6CO_2 + 6H_2O ->[light][chlorophyll] C_6H_{12}O_6 + O_2}$

To balance oxygen, count O on left: 6×2 (from $\ce{CO_2}$) + 6×1 (from $\ce{H_2O}$) = 18 O.
On right: 6 (from $\ce{C_6H_{12}O_6}$) + 2×3 (from $\ce{O_2}$) = 18 O. So we need 6 $\ce{O_2}$:
$\ce{6CO_2 + 6H_2O ->[light][chlorophyll] C_6H_{12}O_6 + 6O_2}$

Answer:

The balanced chemical equation for photosynthesis (the process in chloroplasts converting light energy to chemical energy) is:
$\boldsymbol{\ce{6CO_2 + 6H_2O ->[light][chlorophyll] C_6H_{12}O_6 + 6O_2}}$

(Reactants: $\ce{6CO_2}$ and $\ce{6H_2O}$; Products: $\ce{C_6H_{12}O_6}$ and $\ce{6O_2}$)
