Answer:

101.4pKa

Explanation:

Given parameters:

Initial Volume of helium  = 3.20L

Final pressure of helium  = 59kPa

Final volume on helium gas = 5.5L

Unknown:

Initial pressure exerted on the balloon = ?

Solution;

To solve this pressure - volume problem, we simply apply the Boyle's law.

It states that "the volume of a fixed mass gas varies inversely as the pressure changes if the temperature is constant".

  Mathematically;

         P1 V1  = P2 V2

Now, insert parameters and solve;

         P1 x 3.2 = 59 x 5.5

          P1  = 101.4pKa

sveticcg [70]

Answer:

The answer to your question is  "It will be a high melting point"

Explanation:

Process

1.- Identify the kind of compounds that is Potassium chloride.

Ionic compounds are composed of a metal and a nonmetal.

Covalent compounds are composed of 2 nonmetals.

Potassium chloride is composed of a metal and a nonmetal so, it is  an ionic compound.

2.- Conclude, Potassium chloride has a high melting point because is an ionic compound".
