Answer:
<h2>Density = 8.96 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of copper = 89.6 g
volume = 10 cm³
Substitute the values into the above formula and solve
That's

We have the final answer as
<h3>Density = 8.96 g/cm³</h3>
Hope this helps you
That is not true. Chloroethane has a greater boiling point than ethane.
This is due to the greater intermolecular attraction forces.
The greater electronegativity of Cl than C's, creates a stronger atraction of the electron cloud toward Cl, driving to the formation of permanent dipoles.
Then, in addition to the dispersion forces (present in the ethane and chlorometane) there are forces due to the attraction between the permanent dipoles, which cause a higher boiling point.
It means that the chemical equation is balanced
Diamond for example, will not conduct electricity as there are no mobile ions or electrons to carry electric charge. all the electrons in the carbon atoms in diamond are used for covalent bonding.
another example is chlorine gas, there are also no mobile electrons to carry electric charge.
most covalent compounds cannot conduct electricity, but most ionic and metallic can. however, there are exceptions of course!
