Question

CH3CO2H(I) + 2O2(q) ------------ 2CO2(q) + 2H2O(I)

Determine the number of moles of each product and reactant that would be needed or produced for each situation specified.

CH3CO2H(I)

O2 given 3.7moles

CO2 given 5.2 moles

H2O given 0.75 moles

Answer 1

According to equation the moles of O₂, CO₂ and H₂O are equal, as their coefficients are equal, the moles of CH₃CO₂H are two times less then the moles of any other species.

1) given 3.7 moles O₂, then moles of CO₂ = 3.7 moles, moles of H₂O = 3.7 moles, moles of CH₃CO₂H = 3.7/2= 1.85 moles.

2) given 5.2 moles CO₂, then moles of O₂= 5.2 moles, moles of H₂O=5.2 moles, moles of CH₃CO₂H = 5.2/2= 2.6 moles.

3) given 0.75 moles H₂O, then moles of O₂ = 0.75 moles, moles of CO₂ = 0.75 moles, moles og CH₃CO₂H = 0.75/2= 0.375 moles.
