The answer is b, because all of the other compounds are covelent
<span>Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. We calculate as follows:
PV = nRT
PV = mRT/ Molar mass
m/V = P(molar mass)/RT
Density = P(molar mass)/RT
Density = 2.0 ( 30.97 ) / 0.08206 ( 20 + 273.15) = 2.57 g/L <----First option</span>
For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.
The name and chemical symbol of the elements are
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
<h3>What are chemical symbols?</h3>
Chemical symbols are which are used to represent the elements in the periodic table.
The chemical symbol assigned to elements are usually an abbreviation of the name of the element or the Latin form of the name.
The name and symbol of the given elements are as follows:
- Carbon = C
- Lead = Pb
- Antimony = Sb
- Sodium = Na
- Aluminum = Al
The chemical symbols are used frequently in writing the formula of compound formed from the elements. For example, the compound sodium aluminate which contains sodium, aluminum and oxygen is written in a simplified form as: NaAlO₂.
