Which intermolecular force is most responsible in allowing xenon gas to liquefy?

The amount of arsenic pentasulphide that can be obtained when 35.5 g arsenic acid istreated with excess H₂S in the presence of conc. HCl ( assuming 100% conversion) is :

For x $$ \in $$ R, x $$ \ne $$ -1,

if (1 + x)²⁰¹⁶ + x(1 + x)²⁰¹⁵ + x²(1 + x)²⁰¹⁴ + . . . . + x²⁰¹⁶ =

$$\sum\limits_{i = 0}^{2016} {{a_i}} \,{x^i},\,\,$$ then a₁₇ is equal to :

Let x, y, z be positive real numbers such that x + y + z = 12 and x³y⁴z⁵ = (0.1) (600)³. Then x³ + y³ + z³is equal to :
