What is the kinetic energy, in joules, of a molecule of carbon tetrachloride moving at a speed of 255 m s–1 (use the appropriate
hram777 [196]

Answer:

The kinetic energy of a molecule of carbon tetrachloride is 8.29 zJ.

       

Explanation:

The kinetic energy of a molecule of carbon tetrachloride is given by:

K = \frac{1}{2}mv^{2}

Where:

m: is the mass

v: is the speed = 255 m/s                            

To find the mass we need to find the molar mass for CCl₄, and use the Avogadro's number, knowing that in 1 mol of carbon tetrachloride we have 6.022x10²³ molecules:

A (C) = 12.011 g/mol

A (Cl) = 35.45 g/mol

The molar mass (M) of CCl₄ is:

M = A (C) + 4*A (Cl) = 12.011 g/mol + 4*35.45 g/mol = 153.81 g/mol

Now, the mass of 1 molecule of CCl₄ is:

m = 153.81 \frac{g}{mol}*\frac{1 mol}{6.022 \cdot 10^{23} molecules} = 2.55 \cdot 10^{-22} g = 2.55 \cdot 10^{-25} kg

Finally, the kinetic energy of a molecule of carbon tetrachloride is:

K = \frac{1}{2}mv^{2} = \frac{1}{2}2.55 \cdot 10^{-25} kg*(255 m/s)^{2} = 8.29 zJ

Therefore, the kinetic energy of a molecule of carbon tetrachloride is 8.29 zeptoJoule.

I hope it helps you!

The molecules of the cold element are going to be closer together and still than the molecules of the hot element because the heat energy causes the molecules to be stimulated and to move.

<h3>How do molecules act at different temperatures?
</h3>

In the image you can see the behavior of the molecules when they are in different environments. On the right you see the cold molecules and on the left the hot molecules that are characterized by the following characteristics:

Cold molecules:

  • Molecules together.
  • Molecules with little movement.

Hot molecules:

  • Separate molecules.
  • Molecules with active movement.

A simple example to understand this behavior of molecules is water because:

  • When water is frozen its molecules are almost static and close together.
  • When the water is liquid and it is heated, the molecules move and that is why the water has bubbles, its molecules are separated.
