Final answer:
To find the number of CO2 molecules produced from the reaction of 56 molecules of C6H6, we use the stoichiometry of the balanced chemical equation. For every 2 molecules of C6H6, 12 molecules of CO2 are produced, hence for 56 molecules of C6H6, 336 molecules of CO2 will be formed.
Step-by-step explanation:
The student's question involves calculating the number of CO2 molecules produced in a chemical reaction. Given the balanced chemical equation 2C6H6(l) + 1502(g) → 12CO2(g) + 6H₂O(l), we can determine the number of CO2 molecules produced by a stoichiometric calculation. When 56 molecules of C6H6 react, since the stoichiometry of the reaction is 2 moles of C6H6 to 12 moles of CO2, we simply multiply the number 56 by 6 (as 56 molecules is equivalent to 28 'pairs' of C6H6, and each pair produces 12 CO2 molecules).
Calculating this, we get 56 × 6 = 336 molecules of CO2 produced.
