Question

5. Use the balanced reaction given below to answer the following.

C7H16 (g) + 110₂(g) → 7CO₂ (g) + 8H₂0 (g)
a. How many moles of O₂ are needed to react with 15.84 moles of C7H16?
b. How many moles of CO₂ are produced by the complete combustion of 15.84 moles of
C7H16?
c.
How many moles of H₂O are produced by the complete combustion of 15.84 moles of
C7H16?

Answer 1

Step-by-step explanation:

A) 15.64 moles C7H16 X ( 11 moles O2/ 1 mole C7H16) = 172.04 moles O2

B) 15.84 moles C7 H16 X (7 moles CO2/1 mole C7H16) =110.88 moles CO2

C) 15.84 moles C7H16 X (8 moles H2O / 1 mole C7H16)= 126.72 moles H2O
