Question

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

Answer 1

Multiple choices;

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;

A.Twelve water (H2O) molecules were used to make it.

Explanation;

-The reactants that are required for the process of photosynthesis to take place are; carbon dioxide, water and light energy from the sun.

-The photosynthetic process utilizes 12 water molecules, six carbon dioxide molecules and light energy to produce one glucose molecule, six water molecules and six oxygen molecules.

This can be represented by the following chemical equation:

12H20 + 6CO2 + light energy = C6H12O6 + 6H2O + 6O2

Answer 2

Formation of glucose in the presence of sunlight in plants is represented by the chemical reaction:

6CO2+6H2O->C6H12O6+6O2

You need 6 molecules of carbon dioxide, 6 molecules of water to form 1 glucose molecule and 6 molecules of oxygen.
