Two moles because one moles would be 6.02×10 23 atoms 2 moles would equal twice that number of atoms
A solid that has a high to very high melting point, great hardness, and poor electrical conduction is an : E. Ionic solid
Ionic solid consist of oppositely charge ions. One of the example of Ionic solid is salt (NaCl)
hope this helps
Answer:
Intrusive and Extrusive igneous rocks.
Explanation:
Igneous rocks are defined as those rocks that are formed when magma undergoes the process of crystallization and solidification at or below the earth's surface. For example, Granite, Rhyolite, Gabbro and Diorite.
The igneous rocks are of two different types, namely-
- Intrusive igneous rocks- This type of igneous rocks are formed when the magma crystallizes below or within the earth's crust. For example, Granite.
- Extrusive igneous rocks- This type of igneous rocks are formed when the magma crystallizes and solidifies at the surface of the earth. For example, Basalt.
The Final Pressure of the gas is 6 kPa
<h3>What is Boyle's Law ?</h3>
At constant Temperature , the absolute pressure exerted by the gas is inversely proportional to the volume of the gas.
It is given that
To determine Final Pressure , Boyle's Law will be applied
300 * 2 = P₂ * 100
P₂ = 300 * 2 / 100
P₂ =6 kPa
Therefore the Final Pressure of the gas is 6 kPa.

Answer:
d =~ 5.8μm
d =~ 0.13 μm
Explanation:
when the doping concentrations are 5 × 10^15 cm^-3
d = v^-1/3 ; where d represent the distance between the atoms , and v represent the volume
d =1/ ∛v
d = 1/ ∛5 × 10^15
d = 1/ 170997.5
d = 5.85 × 10 ^ -6
d =~ 5.8μm
when the doping concentrations are 5 × 10^20 cm^-3
d = v^-1/3 ; where d represent the distance between the atoms , and v represent the volume
d =1/ ∛v
d = 1/ ∛5 × 10^20
using the principle of surds and standard forms, we have
d = 1/ ∛0.5 × 10^21
d = 1/7937005.26
d = 1.26 × 10 ^ -7
d = 0.126 × 10 ^ -6
d =~ 0.13 μm
