Which of the following will have lowest freezing point 1)urea 2)table salt?
Urea, with a melting point of 133-135 0C.
What happens to the melting point of urea and cinnamic acid when mixed?
The melting point will be reduced because an impure substance is not held together as strongly as a pure substance therefore it takes less energy to break the bonds or attractive forces holding the impure substance together.
Why does urea and aspirin have higher melting points than napthalene and pi-dicholorbenzene?
Because urea and aspirin overall are polar compounds, and their intermolecular forces are stronger than napthalene or dichlorobenzene. This means it takes more kinetic energy (heat) to separate their molecules, which translates as a higher melting and boiling points.
Is carpet urea same as nitrogen urea?
No,carpet urea is urea formaldehyde it is aproduced by treating urea with formaldehyde
