Question

Consider the formula for glucose: C6H12O6. What does this indicate about the relationship of the reactants to glucose?

A.) Twelve water (H2O) molecules were used to make it.
B.) Twelve hydrogen (H2) molecules were used to make it.
C.) Six oxygen (O2) molecules were used to make it.
D.) Six carbon dioxide (CO2) molecules were used to make it.

Answer 1

The correct option is D.

The reactants that combine together to form glucose are carbon dioxide, water and energy from the sun. Six molecules of carbon dioxide combine with six molecules of water in the presence of sunlight to form glucose. The chemical equation for the reaction is given below"

6CO2 + 6H2O + Sunlight = C6H12O6.

Answer 2

Answer: Option (D) is the correct answer.

Explanation:

Formation of glucose occurs due to a chemical reaction taking place in plants known as photosynthesis.

Therefore, photosynthesis is defined as a chemical process in which plants tend to make their own food in the presence of sunlight, water and carbon dioxide.

During this process, product formed by the plants is glucose and oxygen.

The chemical reaction equation for photosynthesis is as follows.

      $6CO_{2} + 6H_{2}O + \text{Sunlight} \rightarrow C_{6}H_{12}O_{6} + 6O_{2}$

Thus, we can conclude that the statement six carbon dioxide ($CO_{2}$) molecules were used to make it, indicate about the relationship of the reactants to glucose.
