Consider the formula for glucose: c6h12o6. what does this indicate about the relationship of the reactants to glucose? twelve water (h2o) molecules were used to make it. twelve hydrogen (h2) molecules were used to make it. six oxygen (o2) molecules were used to make it. six carbon dioxide (co2) molecules were used to make it.

Answer;

Six carbon dioxide (CO2) molecules were used to make it.

Explanation;

-Glucose is manufactured in the process of photosynthesis, which is the process that is carried out by green plants where they use energy from the sun together with carbon dioxide and water to form simple sugars such as glucose and also release oxygen as a by product.

-This can be shown by the reaction;

6 CO2 + 6 H2O → C6H12O6 + 6 O2

This indicates that six molecules of carbon dioxide are combining with six molecules of water to form glucose molecules C6H12O6, and six molecules of water.

The glucose formed is then stored in form of starch or used in cellular respiration where it is converted to ATP, a form of energy which is used by the cells to drive cellular processes such as growth and transport.

Six carbon dioxide (CO2) molecules were used to make it.

Explanation:

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
