Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Mr. Swerdlow wrote a chemical equation on the board and asked his class what should be changed to make it correct. He wrote:water + carbon dioxide
A
Carbon dioxide should be traded with glucose, and energy should be shown on both sides.
B
Water should by moved to the products side, and glucose and oxygen should both be moved to the reactants side.
C
Water and carbon dioxide should both be moved to the products side, and glucose and oxygen should be moved to the reactants side.
D
Glucose should be moved to the reactants side, and water and carbon dioxide should both be moved to the products side.
Explanation: 

Detailed explanation-1: -The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Detailed explanation-2: -The balanced version is: 6CO2 + 6H2O → C6H12O6 + 6O2.) In simple terms: carbon dioxide + water → glucose + oxygen.

Detailed explanation-3: -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.
