Answer:
The empirical formula is PCl3
Explanation:
Mass of P is 30.97 g, thus 1.523 g of P equivalent to 0.05 moles of P
Mass of Cl is 35.45 g, thus 5.228 g of Cl equivalent to 0.15 moles of Cl
Therefore moles of P : moles of Cl = 0.05:0.15 = 1:3
Therefore the empirical formula, PCl3
Beryllium is a metal so it needs to loose electrons to have a full outer shell while sulfur is a non-metal so it needs to gain electrons to fill its outer shell.

Answer : The energy involved in condensation is, 339 kJ
Explanation :
Formula used :

where,
q = heat required = ?
L = latent heat of vaporization of water = 
m = mass of water = 150 g
Now put all the given values in the above formula, we get:


Therefore, the energy involved in condensation is, 339 kJ
