2O POINTS AND BRAINLIEST!!! FAST ANSWER PLEASE!!!! I WILL FAIL THIS IF YOU DON'T HELP ME!!!!!!

Bread rises because yeast acts on the sugar to produce carbon dioxide and alcohol. C^6H^12O^6 ---> 2 C^2H6^O + 2 CO^2
sugar alcohol carbon dioxide

FILL IN THE BLANKS WITH THE CORRECT AMOUNT OF MOLECULES

The easy way to do this is to remember that the number of molecules is the big number at the very beginning which makes your answer:

__1__ molecule(s) of dextrose sugar yields __2__ molecule(s) of ethyl alcohol plus __2__ molecule(s) of carbon dioxide through the action of yeast. The small amount of alcohol evaporates during baking. __12__ hydrogen atoms are involved in this reaction.

In the given reaction one molecule of dextrose produces two molecules of alcohol and carbon dioxide also.

What is the stoichiometry?

Stoichiometry of the reaction gives idea about the relative amount of species such as reactants and products present in the given chemical reaction.

Given chemical reaction is:

C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂

From the stoichiometry of the reaction, it is clear that:

  • 1 moles of sugar = produces 2 moles of alcohol & 2 moles of carbon dioxide
  • And total number of hydrogen atoms that are present in the given reaction is 12.

Hence, one molecule(s) of dextrose sugar yields two molecule(s) of ethyl alcohol plus two molecule(s) of carbon dioxide through the action of yeast. The small amount of alcohol evaporates during baking. 12 hydrogen atoms are involved in this reaction.
