A measured sample of argon gas has a volume of 20.0 L at a pressure of 660 mm Hg. What is the final volume
valkas [14]

Answer:

C . 24 L

Explanation:

Given data:

Initial volume of gas = 20.0 L

Initial pressure of gas = 660 mmHg

Final volume = ?

Final pressure = 550 mmHg

Solution:

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

660 mmHg × 20.0 L = 550 mmHg × V₂

V₂ = 13200 mmHg. L/ 550 mmHg

V₂ = 24 L

1 mole of phosphoric acid (H3PO4) and 1.75 moles of NaOH are added to the one liter water. Calculate the pH.
Marina CMI [18]
Moles of H⁺ released by each mole of acid = 3
Moles of H⁺ released = 3

Moles of OH⁻ released = 1.75

Moles of H⁺ remaining = 3 - 1.75 = 1.25 mol/dm³

pH = -log[H⁺]
pH = -log(1.25)
pH = -0.1

Match the terms to the correct 
Nadusha1986 [10]
This type of energy travels through vibrations on waves = 7. sound energy

This is the energy found in the nucleus of an atom = 9. nuclear energy

This type of energy can be transferred in three different ways = 6. thermal energy

This is the term used when energy changes from one form to another = 10. energy conversions

This has to do with the speed of an object and how much mass it has = 2. kinetic energy

This can be either kinetic or potential and has to do with the energy of position and motion of an object = 1. mechanical energy

This type of energy is stored energy = 3. potential energy

This is radiant energy from the sun = 5. light energy

This is energy that is transferred by the movement of electrons through a conductor = 4. electrical energy 

This type of energy is often found in things like batteries or food = 8. chemical energy

hope this helps
