Consider these ground-state ionization energies of oneelectron species:
SVETLANKA909090 [29]

Answer:

Explanation:

general expression for the ionization energy of any one-electron species.

=  z² x ground level energy / n²

z is atomic no , n is energy level .

ground level energy of

 H = 1.31 x 10³ kJ/mol

He⁺ = 2² x  1.31 x 10³ kJ/mol  =  5.24 x 10³ kJ/mol

Li²⁺ = 3² x  1.31 x 10³ kJ/mol   = 1.18 x 10⁴ kJ/mol

b ) the ionization energy of B⁴⁺.

= 5² x 1.31 x 10³ kJ/mol  = 32.75 x 10³ kJ/mol  

c )  minimum energy required to remove the electron from the n = 3 level of He⁺ per mole

= 5.24 x 10³ / 9  kJ/mol

= 5.82 x 10² kJ/mol

= 5.82 x 10² x 10³ / 6.02 x 10²³ J

.9667 X 10⁻¹⁸ J

= .9667 X 10⁻¹⁸ / 1.6 X 10⁻¹⁹ eV

= 6.042 eV

= 1237.5 / 6.042

= 204.82 nm

Plastics are synthetic, organic polymers. how are plastics similar and different to polysaccharides
yawa3891 [41]
Plastics and polysaccharides are somewhat similar because they are both polymers. Polymers are a long chain of repeating units called monomers. Their difference, however, is the identity of their monomers. Plastics have hydrocarbons as monomers. Plastics with the monomer ethene is called polyethylene. For polysaccharides, their monomers are simple sugars.

The first word in the name of an ester is derived from the ________ used in the esterification.
oksian1 [2.3K]

The first word in the name of an ester is derived from the alcohol used in the esterification.

<h3>What is esterification?</h3>

Esterification is a chemical process where an organic acid with the formula is combined with an alcohol molecule having the chemical formula (ROH).

The process of esterification is known to produce an ester molecule and during this phenomenon is released water (H2O).

An example of an esterification reaction occurs when ethanoic acid (i.e., the active ingredient of vinegar) can react with C2H5OH (i.e., ethanol) in order to form the ethyl ethanoate molecule, which is a well-known ester molecule.

In conclusion, the first word in the name of an ester is derived from the Alcohol used in the esterification.
