How does lanthanide contraction influence the density of period 6 transition element​

Chemistry
1 answer:
Kitty [74]3 years ago
6 0

Answer:

For example, the atomic radius of the metal zirconium, Zr, (a period-5 transition element) is 155 pm (empirical value) and that of hafnium, Hf, (the corresponding period-6 element) is 159 pm. ... The increase in mass and the unchanged radii lead to a steep increase in density from 6.51 to 13.35 g/cm3.

Whereas ionic bonds join metals to non-metals, metallic bonding joins a bulk of metal atoms. ... Sodium metal is therefore written as Na, not Na+. ... Both of these factors increase the strength of the bond still further. ... Heat capacity: This is explained by the ability of free electrons to move about the solid.

If you had a mixture of ethanol, glycerol, ethylene glycol, methanol, and water, how could you separate these five substances ou
leonid [27]

Fractional distillation

Explanation:

The best way to separate the mixtures out is through the process of fractional distillation.

In fractional distillation, liquid - liquid mixtures are separated based on the differences in boiling point of their components. Let us examine the boiling points of the component of the mixtures:  

     Ethanol                  78⁰C

     Glycerol                290⁰C

     Ethylene glycol     197.6⁰C

     Methanol               64.7⁰C

     Water                     100⁰C

We see that the liquids in the mixture have different boiling points. In this process, the mixture is heated in a distillation column. When the boiling point of any component is reached, it will rise up in the column and can be channeled to a condenser where it is cooled and collected.

The liquid with the least boiling point is first separated with the one with the highest boiling is recovered last:

   Order of recovery;

               Methanol               64.7⁰C

               Ethanol                  78⁰C

                Water                    100⁰C

               Ethylene glycol     197.6⁰C

                Glycerol                290⁰C
