(d) Explain why the first ionisation energy of K is much lower than that of Ar, even though it has a higher nuclear charge.
Include the following in your
• In which quantum shell each outer electron can be found
• How much shielding the outer electron experiences in each atom.

what is the question?

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042

0.42

2.4

24

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
