Question

in a chemical reaction there are molecules that react and the products that are formed from that reaction. please label the reactants and the products on the chemical equation below. (3 points) 6co₂ + 6h₂o ⟶ c₆h₁₂o₆ + 6o₂ dashed boxes reactants products yields identify which reaction represents endothermic and which represents exothermic. (2 points) arrows labeled reactants, products

Explanation:

Part 1: Label Reactants and Products in the Chemical Equation

In a chemical equation, reactants are the substances that undergo the reaction (on the left side of the arrow), yields is the arrow (indicating the direction of the reaction), and products are the substances formed (on the right side of the arrow).

• The equation is: \( 6\text{CO}_2 + 6\text{H}_2\text{O}

ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \)

• Left of the arrow: \( 6\text{CO}_2 \) and \( 6\text{H}_2\text{O} \) are reactants.
• The arrow \(

ightarrow \) is yields.

• Right of the arrow: \( \text{C}_6\text{H}_{12}\text{O}_6 \) and \( 6\text{O}_2 \) are products.

Part 2: Identify Endothermic vs. Exothermic Reactions

• Endothermic Reaction: Absorbs energy (reactants have lower energy than products; energy is a reactant).
• Exothermic Reaction: Releases energy (reactants have higher energy than products; energy is a product).

From the diagram (with “reactants” and “products” arrows):

• If the arrow for reactants is lower than products: The reaction absorbs energy (endothermic, e.g., photosynthesis, which matches the given equation \( 6\text{CO}_2 + 6\text{H}_2\text{O}

ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \), as photosynthesis is endothermic).

• If reactants are higher than products: The reaction releases energy (exothermic, e.g., combustion).

Final Answers (Labeling):

• Reactants: \( 6\text{CO}_2 \), \( 6\text{H}_2\text{O} \)
• Yields: \(

ightarrow \)

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

Final Answers (Endothermic/Exothermic):

• The reaction \( 6\text{CO}_2 + 6\text{H}_2\text{O}

ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \) (photosynthesis) is endothermic (reactants have lower energy than products).

• A reaction like combustion (e.g., \( \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2

ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} \)) would be exothermic (reactants have higher energy than products).

(Note: For the labeling, match the boxes: left box = reactants, middle arrow = yields, right box = products.)

Answer:

• Endothermic Reaction: Absorbs energy (reactants have lower energy than products; energy is a reactant).
• Exothermic Reaction: Releases energy (reactants have higher energy than products; energy is a product).

From the diagram (with “reactants” and “products” arrows):

• If the arrow for reactants is lower than products: The reaction absorbs energy (endothermic, e.g., photosynthesis, which matches the given equation \( 6\text{CO}_2 + 6\text{H}_2\text{O}

ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \), as photosynthesis is endothermic).

• If reactants are higher than products: The reaction releases energy (exothermic, e.g., combustion).

Final Answers (Labeling):

• Reactants: \( 6\text{CO}_2 \), \( 6\text{H}_2\text{O} \)
• Yields: \(

ightarrow \)

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

Final Answers (Endothermic/Exothermic):

• The reaction \( 6\text{CO}_2 + 6\text{H}_2\text{O}

ightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \) (photosynthesis) is endothermic (reactants have lower energy than products).

• A reaction like combustion (e.g., \( \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2

ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} \)) would be exothermic (reactants have higher energy than products).
