Answer 1

The chemical equation for photosynthesis is typically represented as follows:

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

Now, let's break down the number of atoms for each element in the reactants and products:

• Carbon (C):

  • Reactants: 6 (from \(6 , \text{CO}_2\))
  • Products: 6 (from \(\text{C}6\text{H}{12}\text{O}_6\))

• Hydrogen (H):

  • Reactants: 12 (from \(6 , \text{H}_2\text{O}\))
  • Products: 12 (from \(\text{C}6\text{H}{12}\text{O}_6\))

• Oxygen (O):

  • Reactants: 18 (6 from \(6 , \text{CO}_2\) + 6 from \(6 , \text{H}_2\text{O}\))
  • Products: 18 (6 from \(\text{C}6\text{H}{12}\text{O}_6\) + 6 from \(6 , \text{O}_2\))

So the filled boxes would contain:

| Element | Reactants | Products | |----------|-----------|----------| | Carbon | 6 | 6 | | Hydrogen | 12 | 12 | | Oxygen | 18 | 18 |
