In the process of ionization, what is the relationship between the second ionization energy (I2) and the third ionization energy
dimulka [17.4K]
<span>The first ionization energy is the energy that is obligatory in order to eliminate the first electron from an atom(neutral) in the GAS phase
, the second ionization energy is defined as  the energy required to remove the second electron from an atom(+1 ion) in the GAS phase.
</span>the third ionization energy is the energy it takes to remove an electron from a 2+ ion. (That means that the atom has already lost two electrons, you are now removing the third.) 
<span> Ionization energy will normally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods
hope it helps</span>

Calculate the frequency and wavelength for a photon of light with an energy of 3.2x10-19 J.
tamaranim1 [39]

Answer:

wavelength = 6×10⁻⁷m

f = 0.5 ×10¹⁵ Hz

Explanation:

Given data:

Energy of photon = 3.2×10⁻¹⁹ J

Wavelength of photon = ?

Frequency of photon = ?

Solution:

E = h.f

f = frequency

h = planck's constant

E = energy

f = E/h

f = 3.2×10⁻¹⁹ Kg.m².s⁻²/ 6.63×10⁻³⁴ m².Kg/s

f = 0.5 ×10¹⁵ s⁻¹

s⁻¹ = Hz

f = 0.5 ×10¹⁵ Hz

Wavelength:

speed of light = wavelength × frequency

wavelength = speed of light / frequency

wavelength =  3×10⁸ m.s⁻¹ /0.5 ×10¹⁵s⁻¹  

wavelength = 6×10⁻⁷m

*Will give Brainliest* What is the average atomic mass of one molecule of methane, which has one 12C atom and four 1H atoms?
Nesterboy [21]

Answer:

The atomic mass of methane (CH4)is 12 amu for the carbon plus 4 x 1 amu for the four hydrogens, for a total of 16 amu. Therefore, the molar mass of methane is 16g.

pav-90 [236]

Show the two (neutral) organic starting materials that would be used to synthesize the following ketone by a hydroxide mediated crossed‑aldol reaction the product formed is alpha-beta unsaturated carbonyl compound.

<h3>What is the Aldol-condensation ?</h3>

The condensation response among distinctive molecules of an aldehyde or ketone in a protic solvent which includes water or alcohol constitutes the crossed aldol response. When condensation is among distinctive carbonyl compounds, it's far referred to as crossed aldol condensation.

Applying the retrosynthetic evaluation technique, the systems of the beginning substances are decided via way of means of the usage of the bottom catalyzed for the crossed aldol mechanism. The beginning substances are aldehyde and ketone compounds that react with every different to present the goal molecule.
