Question

carbon dioxide + water glucose + oxygen gas drag these tiles and drop them in the correct blank above (c₆h₁₂o₆) (co₂) (h₂o) (o₂)

Explanation:

This is the photosynthesis and respiration equation. For photosynthesis (or the reverse for respiration), we know the formulas:

• Carbon dioxide is $CO_2$, so the first blank next to Carbon dioxide should be $CO_2$.
• Water is $H_2O$, so the blank next to Water is $H_2O$.
• Glucose is $C_6H_{12}O_6$, so the blank next to Glucose is $C_6H_{12}O_6$.
• Oxygen gas is $O_2$, so the blank next to Oxygen gas is $O_2$.

So filling the blanks:

• Carbon dioxide $\boldsymbol{(CO_2)}$ + Water $\boldsymbol{(H_2O)}$ (for the top row, maybe representing reactants or products depending on direction, but here with Glucose and Oxygen as products, it's photosynthesis: $6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6 + 6O_2$)

• Glucose $\boldsymbol{(C_6H_{12}O_6)}$ + Oxygen gas $\boldsymbol{(O_2)}$

Answer:

• Carbon dioxide: $\boldsymbol{(CO_2)}$
• Water: $\boldsymbol{(H_2O)}$
• Glucose: $\boldsymbol{(C_6H_{12}O_6)}$
• Oxygen gas: $\boldsymbol{(O_2)}$
