<h2>Answer : Political Map</h2><h3>Explanation :</h3>
A political map is a kind of map which contains a north arrow, key and a map scale.
This kind of map usually indicates the governmental boundaries of countries, states, or any counties,
And, they give information about the location of major cities, also they usually include significant bodies of water.
Energy can be renewable or nonrenewable.
Combustion involves with heat. The answer is burning wood.
Answer:
![\delta=101.13 g/cm^3](https://tex.z-dn.net/?f=%5Cdelta%3D101.13%20g%2Fcm%5E3)
Explanation:
As can be seen in the Figure in a face-centered cubic unit cell you have:
- Six halves of atoms
- Eight 1/8 of atom (1 in each corner)
In total:
![n_{atom}=6*0.5+8*\frac{1}{8}=4 atoms](https://tex.z-dn.net/?f=n_%7Batom%7D%3D6%2A0.5%2B8%2A%5Cfrac%7B1%7D%7B8%7D%3D4%20atoms)
Now, each side of the cell is 234 picometers (2.34e-8 cm) long
![V_{cell}=L^3=(2.34e^{-8} cm)^3](https://tex.z-dn.net/?f=V_%7Bcell%7D%3DL%5E3%3D%282.34e%5E%7B-8%7D%20cm%29%5E3)
![V_{cell}=1.28*10^{-23}cm^3](https://tex.z-dn.net/?f=V_%7Bcell%7D%3D1.28%2A10%5E%7B-23%7Dcm%5E3)
Atoms per cm3:
![n=\frac{4 atoms}{1.28*10^{-23}cm^3}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7B4%20atoms%7D%7B1.28%2A10%5E%7B-23%7Dcm%5E3%7D)
![n=3.12*10^{23} atoms/cm^3](https://tex.z-dn.net/?f=n%3D3.12%2A10%5E%7B23%7D%20atoms%2Fcm%5E3)
Expressing in mass:
![\delta=3.12*10^{23} atoms/cm^3* \frac{1 mol}{6.022*10^{23}}*195.08 g/mol](https://tex.z-dn.net/?f=%5Cdelta%3D3.12%2A10%5E%7B23%7D%20atoms%2Fcm%5E3%2A%20%5Cfrac%7B1%20mol%7D%7B6.022%2A10%5E%7B23%7D%7D%2A195.08%20g%2Fmol)
![\delta=101.13 g/cm^3](https://tex.z-dn.net/?f=%5Cdelta%3D101.13%20g%2Fcm%5E3)
Answer:
![\boxed{\text{2 mol/L}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7B2%20mol%2FL%7D%7D)
Step-by-step explanation:
![c = \dfrac{ \text{moles} }{ \text{litres}}\\\\c = \dfrac{n }{V }](https://tex.z-dn.net/?f=c%20%3D%20%5Cdfrac%7B%20%5Ctext%7Bmoles%7D%20%7D%7B%20%5Ctext%7Blitres%7D%7D%5C%5C%5C%5Cc%20%3D%20%5Cdfrac%7Bn%20%7D%7BV%20%7D)
Data:
n = 5 mol
V = 2.5 L
Calculation:
![c = \dfrac{ \text{5 mol} }{\text{2.5 L}} = \text{2 mol/L}](https://tex.z-dn.net/?f=c%20%3D%20%5Cdfrac%7B%20%5Ctext%7B5%20mol%7D%20%7D%7B%5Ctext%7B2.5%20L%7D%7D%20%3D%20%5Ctext%7B2%20mol%2FL%7D)
The molar concentration of the solution is
