When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

If a 750 mL of a gas at a pressure of 100.7 kPa has a decrease of pressure to 99.8 kPa, what is the new volume? Show work
SVEN [57.7K]

Explanation:

P1V1 = P2V2

(100.7 kPa)(0.75 L) = (99.8 kPa)V2

V2 = (100.7 kPa)(0.75 L)/(99.8 kPa)

= 0.757 L

Which of the following has the highest ionization energy? Rubidium Zirconium Niobium
____ [38]

Niobium has Highest ionization energy.

<u>Explanation:</u>

The next ionization energy removes an electron from the same electron shell, which increases "ionization energy" due to "increased net charge"of the ion from which the electron is being removed.

Let's compare each of the metals first ionization energies,

Rubidium has its first ionization energy as 403 kJ / mol.

Zirconium has its first ionization energy as 660 KJ / mol.

Niobium has its first ionization energy as 664 KJ / mol.

From the given data above, we can infer that Rubidium has the least Ionization energy whereas Niobium has the highest Ionization energy. We can give the increasing order of the given elements as follows-  

Rubidium < Zirconium < Niobium
