Answer:
40 C atoms
Explanation:
Step 1: Write organic compound
10C₄H₁₀
We see here that in 1 mol of C₄H₁₀, we would have 4 atoms of C.
We are given that we have 10 moles of C₄H₁₀.
Therefore, we have 4 · 10 = 40 atoms C
 
        
             
        
        
        
Answer:
- Compress
- Fixed
- Melts
- Melting Point
- Freezing Point
- High
- Crystalline
- Lattice
- Unit cell
- Amorphous solids
Explanation:
Solids tend to be dense and difficult to <u>compress.</u>
They do not  flow or take the shape of their containers, like liquids do, because  the particles in solids vibrate around <u>fixed</u> points. 
When a solid  is heated until its particles vibrate so rapidly that they are no longer  held in fixed positions, the solid <u>melts</u>.  
<u>Melting point</u> is the  temperature at which a solid changes to a liquid. The melting and <u>freezing point</u>  of a substance are at the same temperature.
In general,  ionic solids tend to have relatively <u>high</u>  melting points, while  molecular solids tend to have relatively low melting points.
Most  solids are <u>crystalline</u>
The particles are arranged in a pattern known  as a crystal <u>lattice</u>
The smallest subunit of a crystal lattice is the <u>unit cell</u>  
Some solids lack an ordered internal structure   and are called <u>amorphous solids.</u>
