Answer:
375 K
Explanation:
Using the experssion shown below as:

At vaporization point, the liquid and the gaseous phase is in the equilibrium.
Thus,

So,

Given that:

Also, 1 kJ = 10³ J
So,


So, temperature is :


<u>T= 375 K</u>
Answer:
Al2(SO4)3
Explanation:
Looking at this carefully, we will discover that Al2(SO4)3 is composed of Al^3+ and SO4^2-.
The aluminum and sulphate ions are ionically bonded. However, the oxygen and sulphur in the sulphate ion are covalently bonded.
Hence, Al2(SO4)3 contains both ionic and covalent bond.
