Madalyn Houston · Answer 1

10.4moles of CO2

Explanation:

2C2H6 + 7O2 - > 4CO2 + 6H2O

From the equation,

2moles of C2H6 produced 4 moles of CO2.

Therefore, 5.2moles of C2H6 will produce = (5.2 x 4) / 2 = 10.4moles of CO2

Graham Russo · Answer 2

10.4 moles of CO2 are produced

Explanation:

take the 5.2 moles of C2H6 and multiply that by the mole ratio of CO2 to C2H6 in the reaction (4/2)

5.2 * (4/2) = 10.4
