Option D: Chromium would require the most energy to convert one mole of gaseous atoms into gaseous ions each carrying two positive charges.
<h3>What does the term “ionization energy” mean? </h3>
The ionization energy measures an element’s ability for participating in any chemical processes that calls up for the creation of ions or the donation of other electrons.
It is defined as the energy that any electron present in a gaseous atom or ion has in order to absorb so that it comes out of the influence of the nucleus and hence freely move
Ionization energy is also said as the minimum energy required to remove the most loosely bound electron that is present in an isolated gaseous atom or a positive ion or a molecule.
It can be easily connected to the type of chemical bonds that exist between the components in the compounds that they form.
<h3>Which element ionizes most energetically?</h3>
Helium, because it has the highest first ionization energy, whereas francium has one of the lowest.

Answer:
The concentration of 
that should used originally is 
Explanation:
From the question we are told that
The necessary elementary step is
The time taken for sixth of 0.5 M of reactant to react 
The time available is 
The desired concentration to remain 
Let Z be the reactant , Y be the first product and X the second product
Generally the elementary rate law is mathematically as
Where k is the rate constant , 
is the concentration of Z
From the elementary rate law we see that the reaction is second order (This because the concentration of the reactant is raised to power 2 )
For second order reaction
Where 
is the initial concentration of Z which a value of 
From the question we are told that it take 9 hours for the concentration of the reactant to become
So
=> 
For 
Answer: ¹²₅C
Explanation:
¹²₅C is incorrect. The superscript is the atomic mass. This varies between each element. The subscript is the atomic number. This doesn't change. You will see every element has the correct atomic atomic number except for Carbon. Carbon should have atomic number 6.
Answer:
It increases by a factor of eight
Explanation:
When temperature is held constant, gas pressure changes according the volume, in undirectly proportion.
Volume increases → Pressure decreases
Volume decreases → Pressure increases
As volume gas, was reducted from 4L to 0.5L, it was reduced by 1/8, so the pressure gas was increased by a factor of eight.
