Question

if 23 liters of oxygen are consumed, how many liters of CO2 are produced?
Use the equation: C3H8 + O2 → CO2 + H20
A. 12L
B. 18L
C. 19.2L
D. 13.8L

Answer 1

Answer:

13.8L OF CO2 WILL BE PRODUCED

Answer 2

Answer:2C4H10 + 13O2 ==> 8CO2 + 10H2O  Balanced equation

moles C4H10 present = 23.2 g x 1 mole/58.12 g = 0.3992 moles C4H10

At STP 1 mole of gas = 22.4 liters, so ..

0.3992 moles C4H10 x 22.4 L/mole = 8.94 liters of C4H10

From the balanced equation, mole ratio of CO2 : C4H10 is 8 : 2 so to find moles or liters of CO2 use this ratio.

Liters CO2 = 8.94 liters C4H10 x 8 liters CO2/2 liters C4H10 = 35.8 liters CO2 produced

Explanation:Volume of O2 required = 8.94 L C4H10 x 13 L O2/2 L C4H10 = 58.1 liters of O2 required
