Calculate the molar mass of Iron (II) chloride (3 sig figst

127g/mol

Explanation:

First, let us write the formula of Iron (II) chloride. This is illustrated below:

From name of the compound, we discovered that iron has oxidation number of 2.

Therefore, Iron (II) chloride is written as FeCl2

Now, we can obtain the molar mass of FeCl2 as follow:

Molar Mass of FeCl2 = 56 + (35.5 x 2) = 56 + 71 = 127g/mol

the answer is   c.) 1575 j.

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
