2C3H7OH + 9O2 -> 6CO2 + 8H2O How Many Moles of CO2 can be produced by reacting 6 moles of C3H7OH with oxygen?

Up to .

Explanation:

The equation for this reaction: is indeed balanced.

Notice that the coefficient of is while that of is .

Therefore, each unit of this reaction would consume units of while producing units of . In other words, this reaction would produce three times as much as it consumes .

If all that of molecules are actually consumed through this reaction, three times as many molecules would be produced. That corresponds to of molecules.

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.
