1) Draw representations of both ionic solids in each set that show the relative differences in the sizes of the four ions, the ratio of cations to anions, and the

charge on each ion; identify which ionic solid will have the higher melting

temperature; and justify your answer. (Formula units that contain two ions must

be drawn as networks consisting of twelve ions in total. Formula units that

contain more than two ions can be represented as a single formula unit.)

a. NaCl or KBr

b. NaCl or MgS

c. BeF, or Lif

d. CaO or CaCl2

e. Mgo or A103

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.
