A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, he used the ideas just developed in class about density. First he measured the mass of the metal to be 169.7 grams. Then he dropped the metal into a measuring cup and found that it displaced 16.0 mL of water.

Calculate the density of the metal.
Density =
g / mL

Use the table below to decide the identity of the metal. This metal is most likely
.

Hcn is the correct answer leave a good rate and .

Van der waals forces are temporary electromagnetic forces established between uncharged atoms. some neutral molecules, when close together, can become temporarily “charged,” as electrons move around the atom. water is a polar molecule, the side of the molecule that the hydrogens bond to being more positive, and the opposite side bound to the lone pairs of electrons being more negative. this means that it participates in dipole-dipole interaction (non-polar exhibits dispersion forces), and it has the capacity for hydrogen bonding.
