Question

The combustion of ethane ( C 2 H 6 ) produces carbon dioxide and steam. 2 C 2 H 6 ( g ) + 7 O 2 ( g ) ⟶ 4 CO 2 ( g ) + 6 H 2 O ( g ) How many moles of CO 2 are produced when 5.20 mol of ethane is burned in an excess of oxygen?

Answer 1

Answer:

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

Answer 2

Answer:

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
