Why do the D blocks elements show different Oxidation State​

Chemistry
1 answer:
denis-greek [22]3 years ago
3 0

Answer:

These elements show variable oxidation state because their valence electrons in two different sets of orbitals, that is (n-1)d and ns. The energy difference between these orbitals is very less, so both the energy levels can be used for bond formation.

Question
VMariaS [17]

Answer:

12.62 L

Explanation:

First, we have to calculate the moles corresponding to 18.0 g of oxygen gas (MW 32.0).

18.0 g × (1 mol/32.0 g) = 0.563 mol

Then, we can find the volume occupied by 0.563 moles of oxygen at STP (273,15 K, 1.00 atm) using the ideal gas law.

P × V = n × R × T

V = n × R × T / P

V = 0.563 mol × 0.0821 atm.L/mol.K × 273.15 K / 1.00 atm

V = 12.62 L

The kilocalories in one can of cola if it has 40. g of carbohydrate and no fat or<br> protein
Marysya12 [62]

Answer:

One can of cola contain 0.16 kcal of carbohydrates.

Explanation:

Given data:

mass of cola can = 40 g

kilocalories of carbohydrates = ?

Solution:

we know that there are 4 cal of carbohydrates per gram.

40 g × 4 cal/g = 160 cal

Now we will convert calories into kilocalories. There are 1000 calories in one kilocalories so,

160/1000 = 0.16 kcal

so, one can of cola contain 0.16 kcal of carbohydrates.

A ground-state H atom absorbs a photon of wavelength 94.91 nm, and its electron attains a higher energy level. The atom then emi
vitfil [10]

The intermediate energy level that the electron reached from the ground state is; n= 3.

<h3>What are energy levels in an atom?</h3>

The fixed distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells). Higher energy electrons have greater energy as you move out from the nucleus.

A region of space within an energy level known as an orbital is where an electron is most likely to be found.

The formula to get the higher level is Rydberg's formula;

1/λ = R(1/n₁² - 1/n₂²)

where;

R is rydberg constant = 1.097 × 10⁷ m⁻¹

We want to find the intermediate level where wavelength = 1281 nm = 1281 × 10⁻⁹ m

Thus;

\frac{1}{1280(10^{-9})} = 1.097*10^{7}(\frac{1}{n_{2}^{2}}-\frac{1}{5^{2}})  \\0.0712=\frac{1}{n_{2}^{2}}-\frac{1}{25}  \\\frac{1}{n_{2}^{2}}=0.0712+\frac{1}{25}\\\frac{1}{n_{2}^{2}}=0.1112

n₂ = √(1/0.1112)

n₂ ≈ 3
