Consider the figure below. In the case of butane, diethyl ether, and water, the heat of vaporization is considerably larger than heat of fusion. Explain this phenomenon. Note that the nature of intermolecular interactions does not change through the phases because the molecules does not undergo chemical changes.

is there multiple choice answers?

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
