The electrons rearrange themselves to ensure that orbitals at lower energy levels are first filled before those at higher energy levels.

<h3>Electronic configuration</h3>

One of the rules of electronic configuration states that lower energy level orbitals are first filled with electrons before higher energy level orbitals.

Thus, the electrons in Gold will rearrange themselves to obey the above rule in order to achieve more stability.

Hence, the electronic configuration becomes: 4f^{14}, 5d^{10} ,6s^1

What is the IUPAC name for the compound FeS?
densk [106]
The correct answer is option 3. The IUPAC name is Iron(II) sulfide. It is the less stable amorphous form.  When this is powdered, it is pyrophoric or it ignites spontaneously in air. It readily reacts with hydrochloric acid producing hydrogen sulfide.

10. Identify the products in the combustion of methane.
Oksanka [162]

Answer:

a. CO2 and H20

Explanation:

Chemically, this combustion process consists of a reaction between methane and oxygen in the air. When this reaction takes place, the result is carbon dioxide (CO2), water (H2O), and a great deal of energy. The following reaction represents the combustion of methane:

CH4[g] + 2 O2[g] -> CO2[g] + 2 H2O[g] + energy

One molecule of methane, (the [g] referred to above means it is gaseous form), combined with two oxygen molecules, react to form a carbon dioxide molecule, and two water molecules usually given off as steam or water vapor during the reaction and energy.

An aqueous solution is 4.44 M nitric acid and the density of the solution is 1.42 g/mL. Calculate the mole fraction of this solu
prohojiy [21]

The mole fraction of HNO3 is  0.225

<u>Explanation:</u>

<u>1.</u>Given data

Density = 1.429 /ml

Mass% = 63.01 g HNO3 / 100g of solution

The mass of 63.01 g is in 100 / 1.142 /ml of solution

Or 63.01 g in 55.7 mL

Molarity = 15.39 moles / L

Mass of water in 100g = 100 - 63.01=36.99 g

So 63.01 grams in 36.99 grams of water

So mass of HNO3 in 1000grams of water = 63.01* x 1000 / 36.99 = 1703

Moles of HNO3 in 1000g = 1703 / 63.01 = 27.03 moles

Molality = 27.03 molal (mole / Kg)

Mole fraction = Mole of HN03 / Moles of water + mole of HNO3

Mole of water = 62/ 18 = 3.44

Moles of HNO3 = 63.01 / 63.01 = 1.000

Mole fraction = 1.000 / 3.44 + 1.000 = 0.225

The mole fraction of HNO3 is  0.225
