Mrs. zerlinsky wrote a chemical equation on the board and asked her class what should be changed to make it correct. she wrote: water + glucose → carbon dioxide + oxygen + energy what should be changed to show the correct chemical reaction? water should be traded with oxygen. glucose should be traded with oxygen. water should be traded with carbon dioxide. glucose should be traded with carbon dioxide.

Water and Oxygen should be swapped.

Explanation:

The correct order should be:

Oxygen + Glucose  --- becomes --- Carbon Dioxide + Water +  Energy

Oxygen and Glucose react to become Carbon Dioxide and Water, providing energy in the process.

The chemical equation is:

C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy

For each molecule of Glucose, C6H12O6, it takes 6 Oxygen atoms, or three pairs, to combine with the Glucose. The results are 6 molecules of CO2 and 6 molecules of H2O. The result is that energy is released, transferred.
