Photoelectron spectroscopy (pes) is a technique used for determining the ionization
potentials of molecules. Underneath the banner of PES are two separate techniques for
quantitative and qualitative measurements. They are ultraviolet photoeclectron
spectroscopy (UPS) and X-ray photoelectron spectroscopy (XPS). UPS focuses on
ionization of valence electrons while XPS is able to go a step further and ionize core
electrons and pry them away.
The chemical formulae of the given compounds are as follows:
- Magnesium chloride: MgCl₂
- Aluminium chloride: AlCl₃
- Calcium oxide: CaO

Answer:
be able to meet long term timber needs.
Explanation:
Forest Services has been indicated for a long time the exhaustion of timer in the United States. However, in the recent decade, this trend has shown a reverse. The creation of nuclear energy and other technological developments that bring about drastic changes in our way of life. Gradually, the forest has recovered its trees and plants, and it is anticipated that timber will be available to meet long-term wood needs.
Answer:
The answer is
<h2>241.15 kPa</h2>
Explanation:
To find the pressure in kilopascals we must first find the pressure in Pascal
To find the pressure in Pascal we use the conversion
1 atm = 101 , 325 Pa
If 1 atm = 101325 Pa
then 2.38 atm = 2.38 × 101325
= 241153.5 Pa
Converting it into kPa we have the final answer as
<h3>241.15 kPa</h3>
Hope this helps you
