Answer:

32000atm

Explanation:

Using Boyle's law equation;

P1V1 = P2V2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (

V2 = final volume (L)

According to the question below:

P1 = 160.0 atm

P2 = 3.0 atm

V1 = 600L

V2 = ?

Using P1V1 = P2V2

160 × 600 = 3 × V2

96000 = 3V2

V2 = 96000/3

V2 = 32000atm

What term describes the process of lowering the boiling point of a hydrocarbon by exposing it to different environmental treatme
IgorLugansk [536]

Answer:

Hydrocarbon can be defined as an organic compound that comprises of hydrogen and carbon only.

In Organic chemistry, cracking refers to the process of lowering the boiling point of a heavy, complex or long-chain hydrocarbon such as kerogens by exposing it to different environmental treatments such as hydrogen enriched catalysts, pressure or high temperatures, in order to produce smaller, lighter and more useful molecules (alkanes and alkenes) such as gasoline, diesel fuel, etc.

What is the molarity of a 5.0 L solution that contains 0.5 moles of KNO3
pashok25 [27]

Answer:

Molarity of a 5.0 L solution that contains 0.5 moles of KNO3 is 0.1 M

Explanation:

Molarity : It is used to express the concentration of the solution and defined as total moles of solute present in one liter of solution .

Molarity =\frac{moles\ of\ solute}{volume\ of\ solution(L)}

Moles of KNO3 = 0.5 (given)

Volume of solution = 5.0 L

Substitute the value in given formula ,

Molarity =\frac{0.5\ moles }{5.0\ L}

on calculation,

Molarity = 0.1 mol/L

Molarity = 0.1 M

(M = mol/L)
