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

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.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
