#1: The molecules of which phase have the greatest intermolecular forces, compared to their kinetic energies?

A. plasma

B. gas

C. liquid

D. solid

***debating between A and C... what do u think @chmvijay is it plasma? or liquid?

#5: On the basis of structure, which of the following solids is the most brittle?

A.       CaF2

B.       C6H12O6

C.       Cu

D.       Au

***my answer; B

cuz sugar is most brittle right??? :D

chmvijay · Answer

ionic bonds between metals and nonmetals

chmvijay · Answer

CaF2

anonymous · Answer

why is it CaF2?? :/

anonymous · Answer

and so #4 is A.    ionic bonds between metals and nonmetals ??

anonymous · Answer

so calcium fluoride is more brittle than sugar? :/

anonymous · Answer

and what about 1 and 2 ?

chmvijay · Answer

just thinking wait

anonymous · Answer

haha alright :)

chmvijay · Answer

1. solid

anonymous · Answer

okay!

chmvijay · Answer

2 nd IDK LOL:(

anonymous · Answer

oh oaky haha thanks :)

so #1 = solid

2= idk haha

3= A

4= A

and 5= A.    CaF2  ???? NOT B??

anonymous · Answer

@chmvijay :) just double checking?!!
