C was the answer i had and it was right
Answer:
Explanation:
Melting and boiling point variations are not clear (do not have uniform pattern) in periodic table. But we can see, some elements have higher melting and boiling points and some have less. Here we study melting and boiling points of s, p, d blocks elements. IVAth group elements (C,Si) show high melting and boiling points because they have covalent gigantic lattice structures.
Answer:
now this area isn't my expertise so take this with a grain of salt but I believe its about 91125 g
Explanation:
8 cm is about 45g cube that and its 91125 g
i dont really know i will find some more information on that in about 5 minutes
Two non metal combined together and form the bond is called covalent bond
Note - yellow color molecules in pictures are non metal elements
example - co2 , so2,
