Regents Chemistry Exam August 2024 Question 43
43 Given the incomplete equation for a fermentation reaction:
X → 2CH3CH2OH + 2CO2
Which formula represents the missing reactant, X, in this equation?
(1) C5H6O5
(3) C6H6O6
(2) C5H12O5
(4) C6H12O6
Solution:
To find X, we need to find the number of atoms of each elements on the product side. 2CH3CH2OH + 2CO2 means there are 6 carbons, 6 oxygens and 12 hydrogens. Choice 4 must be the correct answer.
