Why does foliation occur? (Metamorphic rock)

Chemistry
2 answers:
Ulleksa [173]2 years ago
8 0
It happens due to pressure acting on the minerals in metamorphic rock. Slate is a good example of what foliation looks like.

Foliation occurs when the pressure squeezes the flat or elongated minerals within a rock so that they become aligned.

How many moles of helium are 8.84×1024 atoms of He?
insens350 [35]

Answer:

14.68 moles of He

Explanation:

To do this, just remember Avogadro's Constant or Avogadro's number. This constant tells us how many units ( in this case atoms) there are in a mole of ANY type of substance.

Avogadro's constant is 6.022140857 × 10²³ units per mole.

Now that we know how many atoms there are in 1 mole, we can use this as our conversion factor.

8.84 x 10²⁴ atoms of He →  moles of He

8.84\times10^{24} atoms of He\times\dfrac{1moleofHe}{6.022140857\times10^{23}atomsofHe}=14.68molesofHe

So the answer would be:

14.68 moles of He

Which ion has the lower ratio of charge to volume? Explain.<br> (b) Sc³⁺ or Ca²⁺
WINSTONCH [101]

Ca²⁺ion has a lower ratio of charge to volume.

The charge density of an ion is defined as the ratio of the charge of an ion to its volume. Scandium ion has high charge density than calcium ions. The charge density of an ion is defined as the ratio of the charge of an ion to its volume.

Charge density also depends on the size of the ion and valence electrons. The volume of an ion increases with its size. It is inversely proportional to ion volume and directly proportional to charge magnitude. Scandium and calcium are IV periodic elements with atomic numbers of 21 and 20 respectively. Scandium loses three electrons and has a +3 charge and calcium is a divalent cation. Hence, the Scandium ion has high charge density than the calcium ion.
