The molar mass for PCL3 is 137.33 g/mol
Answer:A
Explanation:
The melting points of solids depend in the relative sizes of ions in the ionic lattice. The smaller the relative sizes of the ions, the higher the lattice energy and the stronger the lattice hence higher melting point. Comparing relative ionic sizes, fluoride ion is lesser in size than chloride ion hence NaF has a higher melting point than NaCl.
Answer:
When energy is removed in liquid water then it will solidify since heat is given off by the system to its surrounding. It is an exothermic process where the enthalpy decreases since heat is taken off. So liquid water becomes ice in an exothermic process.
