The overall process of photosynthesis has the balanced chemical equation 6CO2 + 6H2O → C6H12O6 + 6O2. What does this tell you about the relative amounts of carbon dioxide and water consumed in this process? Question 8 options: A) For every six moles of carbon dioxide consumed, one mole of water is consumed. B) For every gram of carbon dioxide consumed, one gram of water is consumed. C) For every six grams of carbon dioxide consumed, one gram of water is consumed. D) For every mole of carbon dioxide consumed, one mole of water is consumed.

D) For every mole of carbon dioxide consumed, one mole of water is consumed.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
