Iron(III) oxide and hydrogen react to form iron and water, like this: Fe2O3 + 3H2 → 2Fe + 3H2O

At a certain temperature, a chemist finds that a 5.4L reaction vessel containing a mixture of iron(III) oxide, hydrogen, iron, and water at equilibrium has the following composition:

Compound Amount
Fe2O3 3.54g
H2 3.63g
Fe 2.37g
H2O 2.13g

Calculate the value of the equilibrium constant for this reaction. Round your answer to significant digits.

Explanation:

the answer is definitely c.

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.
