Why does silicon have a high melting point
Igoryamba
If the bonds are held together tightly, as an ionic bond or even a covalent bond, there will need to be a strong force to separate those bonds. This would by why their would be a high melting point. Another reason would be re-activity. <span />

What will be the boiling point of a solution of 8 moles of sodium dichromate (Na2Cr2O7) dissolved in 8 kg of water? Use the foll
nexus9112 [7]

Answer:

1. 374.69 K

Explanation:

Hello,

In this case, pure water's boiling point is 373.15 K, thus by considering the boiling point increase equation:

\Delta T=imKf

Whereas i=2 since two ionic species are formed,actually, the experimental value is 2.42 so better work with it, thus:

\Delta T=2.42*(\frac{8}{8}m)*0.512 Km^{-1}=1.239K

Thus, the required boiling point is:

T_b=373.15K+1.239K\\T_b=374.69K

Regards.
