Explanation:
Both diamond and SiO₂ are network solids. Their atoms are all joined together so a crystal of either diamond or SO₂is one giant molecule.
Structure
In diamond, each C atom is covalently attached to four other C atoms.
The structure of SiO₂ is like that of diamond. The difference is that there is an O atom between each atom of Si.
Properties
Both substances are
- High-melting
- Hard
- Insoluble in both polar and nonpolar solvents
- Poor conductors of electricity
Answer:
Density = 2.5 g/cm³ , The metal is aluminium.
Explanation:
Density is defined as the ratio of the mass and the volume
Thus,
Given that:
Mass = 612 grams
Volume = 245 cm³
Thus, Density is:
<u>Density = 2.5 g/cm³</u>
Metals are shiny with high density.
<u><em>The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range. </em></u>
<u><em>The metal is aluminium.</em></u>
