1 answer

Let's analyze the reaction you've provided:

\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} \rightarrow \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \]

  1. How many molecules of carbon dioxide are involved in this reaction?

    • There are 6 molecules of carbon dioxide (CO₂) involved in this reaction.
  2. How many molecules of sugar are produced in this reaction?

    • The reaction produces 1 molecule of glucose (C₆H₁₂O₆).
  3. How many atoms of carbon are on the left of the equation? How many on the right?

    • On the left side (reactants), each molecule of CO₂ has 1 carbon atom. Since there are 6 molecules of CO₂, there are \(6 \times 1 = 6\) carbon atoms.
    • On the right side (products), each molecule of glucose (C₆H₁₂O₆) has 6 carbon atoms. Therefore, there are 6 carbon atoms on the right side.

In summary:

  • 6 molecules of CO₂ are involved.
  • 1 molecule of sugar (C₆H₁₂O₆) is produced.
  • 6 carbon atoms are present on both sides of the equation.
