Determine the oxidation state for each of the elements below. The oxidation state of ... silver ... in ... silver oxide Ag2O ... is ... ___ . The oxidation state of sulfur in sulfur dioxide SO2 is ___ . The oxidation state of iron in iron(

The oxidation state of silver in is .

The oxidation state of sulfur in is .

Explanation:

The oxidation states of atoms in a compound should add up to zero.

There are two silver atoms and one oxygen atom in one formula unit of . Therefore:

.

The oxidation state of oxygen in most compounds (with the exception of peroxides and fluorides) is . Silver oxide isn't an exception. Therefore:

.

Solve this equation for the (average) oxidation state of :

.

Similarly, because there are one sulfur atom and two oxygen atoms in each molecules:

.

The oxidation state of in is also , not an exception, either.

Therefore:

.

Solve this equation for the oxidation state of here:

.

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.
