Answer:

<h3>Electronic configuration of Potassium (K) </h3>

Atomic number of potassium = 19

Therefore number of electrons = 19

Since, maximum number of electrons in outermost orbit will not be more than 8, thus the 19th electron of potassium atom will reside in 4th.

Thus, electronic configuration of potassium is

given in first pic.

Number of orbit in potassium = 4

<h3>Electronic configuration of Calcium (Ca) </h3>

Atomic number of calcium = 20

Therefore number of electrons = 20

Thus, electronic configuration of calcium is given in sec pic.

Number of orbit in calcium = 4

Explanation:

The given cation:

(Rf₂Al₂F₃)³⁺

The oxidation number gives the extent to which a specie is oxidized in a reaction.

This number is assigned based on some rules:

Elements in combined state whose atoms combines with themselves have an oxidation number of zero.
The charge carried on simple ions gives their oxidation number.
Algebraic sum of all the oxidation numbers of atoms in neutral compound is zero. In an ion with more than one kind of atom, the charge on it is the oxidation number.

for the specie given;

Known:

oxidation number of Al = +3

F = -1

charge = +3

let the oxidation number of Rf = k

2k + 2(3) + 3(-1) = +3

2k + 6 - 3 = 3

2k = 0

k = 0

The oxidation state of rutherfodium is 0

Write the Rate Law

Ivanshal [37]

As we know that rate law expression is

$r = k { |a| }^{2} { |b| }^{2}$

(a)

$r = k { |o2| }^{1} { |no2| }^{2}$

(b)

$r = k { |cl2| }^{1}$

(c)

$r = k { |chcl3|}^{1} { |cl2| }^{1}$

What is the empirical formula for propene C3H6

USPshnik [31]

The empirical formula is the simplest formula attainable while maintaining the ratio so it will be CH2.

Explanation:

The empirical formula of a chemical compound is the simplistic positive integer ratio of atoms being in a compound. A simple example of this thought is that the empirical formula of sulfur monoxide, or SO, would simply be SO, as is the empirical formula of disulfur dioxide, S2O2.
