tekilochka [14]3 years ago

Answer:

D. s, p

Explanation:

Principle energy levels        number of sublevels               number of electrons

              1                                            1s                                   2n² = 2(1)²= 2

             2                                           2s                                   2n² = 2(2)²= 8  

                                                          2p  

             3                                            3s                                 2n² = 2(3)²=  18    

                                                           3p

                                                           3d

when an atom has 2 energy level it has 1 sublevel (s) in 1st energy level 2 sublevels or orbitals  (s ans p) in second energy.

The total number of electrons accommodate by atoms with n=2 are 10. two electrons in 1s two electrons in 2s and six electrons in 2p.

Brums [2.3K]
The reaction is shown below,

Step 1: Hydration of Alkene:
                                            In first step Ethene is hydrated to Ethanol through Hydroboration Reaction.

Step 2: Oxidation of Primary Alcohol:
                                                          In this step partial oxidation of ethanol is carried out using mild Oxidizing agent <span>Pyridinium chlorochromate (PCC) and Acetaldehyde is produced.

Step 3: Reduction of Acetaldehyde followed by Oxidation:
                                                                                           In this step, first acetaldehyde is reduced to secondary alcohol using grignard reagent. After that the sec. alcohol is oxidized to ketone by using oxidizing agent CrO</span>₃.

In the solvent pair experiment that is being carried out with the solid that is being recrystallized, why do you not have to wor
kumpel [21]

You do not have to worry  because it will not affect the yield of the pure crystals.

<h3>What is re-crystallization?</h3>

Re-crystallization is the process of obtaining pure crystals from a super saturated solution.

This is done by heating a solution of the impure substance to a high temperature and then allowing the hot solution to cool down and the crystals begin to appear.

You do not have to worry about sudden vigorous boiling of crystal solution when you add the second solvent to the solution because it will not affect the yield of the pure crystals.

QUE VENTAJAS TIENE PARA LA PLANTA Y EL CULTIVO LA PERMANENCIA DEL POTASIO COMO CATION MONOVALENTE (K+)?
yarga [219]

Explanation:

Son muchos los beneficios del catión monovalente (K+) en las plantas y cultivos, mencionaremos algunos:

-Interviene en el proceso de apertura y cierre de los estomas; el catión (k+) ayuda a que los estomas puedan realizar correctamente  el proceso de la fotosíntesis es decir  la absorción del dióxido de carbono para producir oxígeno y agua; este proceso ayuda a que la planta pueda fabricar su propio alimento es decir transformar materiales inorgánicos en orgánicos como azúcares y carbohidratos que son aprovechables por la planta para realizar diversas funciones catalíticas como la respiración celular,la fosforilación y la síntesis de proteínas; este proceso también contribuye a que la planta pueda almacenar y retener suficiente agua lo cual ayuda a evitar el estrés hídrico en la planta.

Por lo tanto si la planta tiene una buena concentración de potasio como catión monovalente(k+); es posible que tenga un buen crecimiento y desarrollo radicular ,así mismo la calidad de los cultivos será muy buena,seran cultivos muy nutritivos y saludables. Algunos cultivos que necesitan una alta cantidad de potasio son los cítricos y el banano.
