kotegsom [21]
<span>It’s easier to determine the elecron configurations for the p-block elements in periods 1,2,3 than to determine the electrons configurations for the rest of the p-block elements in the periodic table beacause from period 4, specifically from the element 31 (Ga), the atoms start to fill the d orbitals, and the energy levels of the 3d orbitals ara quite similar to the energy levels of 4p orbitals. So, for the elements Cr and Cu the right configurations do not match the configurations predicted using Aufbau method and Hund rules. Those are not the only exceptions but the two first. All is due to the proximity of the energy of the d and p orbitals and the fact that the rearrangement of the electrons result in a lower energy level. </span>

An analytical chemist has determined by measurements that there are 8.5 moles of magnesium in a sample of talc. How many moles o
MrRissso [65]

There are 5.66 moles of hydrogen in the sample of talc(hydrated magnesium silicate).

Given,

Talc formula is  Mg_{3} Si_4O_{10} (OH)_2

moles of magnesium = 8.5 moles

The stoichiometry of magnesium and hydrogen is 3 : 2,

So 3 moles of magnesium is equivalent to 2 moles of hydrogen.

Then 8.5 moles of magnesium is equivalent to \frac{2}{3} *8.5=5.6666 moles

<h3>Talc </h3>

Talc(hydrated magnesium silicate), often known as talcum, is a type of clay mineral made up of hydrated magnesium silicate, having the formula Mg3Si4O10(OH)2. Baby powder is made of powdered talc, frequently mixed with corn starch. This mineral serves as a lubricant and thickening agent. It serves as a component in paint, pottery, and roofing materials. It serves as a key component in many cosmetics. It can be found as foliated to fibrous aggregates and in a remarkably uncommon crystal form. It is foliated with a two-dimensional platy form, has a flawless basal cleavage, and an irregular flat fracture.

Talc(hydrated magnesium silicate), the softest mineral, is assigned a value of 1 on the Mohs scale of mineral hardness, which is based on scratch hardness comparisons.
