Question

In this reaction, how many moles of ethane (C2H6) would react with 35 moles of 02? 2C2H6 + 702 + 6H20 + 4CO2 O
A. 30 O
B.2 O
c. 10
D. 20​

Answer 1

Answer:

C = 10

Explanation:

Given data:

Moles of O₂ = 35 mol

Moles of C₂H₆ react = ?

Solution:

Chemical equation:

2C₂H₆  + 7O₂      →    6H₂O + 4CO₂

Now we will compare the moles of O₂ with C₂H₆.

                  O₂         :        C₂H₆

                   7          :          2

                35          :        2/7×35 = 10 mol

Option C is correct.
