Answer: The given statement is true.
Explanation:
Chemical bonds are defined as the bonds formed due to interaction of electrons of two same or different atoms. Basically, these electrons are physically attracted towards each other because of which either sharing or transfer of electrons tend to take place.
For example, Cl has 7 valence electrons and sodium has 1 valence electron. In order to gain stability when both sodium and chlorine will come closer then Cl will attract one electron from sodium leading to the formation of a new compound NaCl.
Thus, we can conclude that the statement chemical bonds are physical attractions between atoms resulting from the interaction of their electrons, is true.

Answer:
9.34 cm³
Explanation:
From the question given, we obtained the following data:
Mass of magnesium = 16.24 g
Volume of magnesium =.?
To obtain the volume of the magnesium sample, we simply apply the formula for calculating the density of samples. This is illustrated below:
Mass of magnesium = 16.24 g
Density of magnesium 1.738 g/cm³
Volume of magnesium =.?
Density = mass /volume
1.738 = 16.24/volume
Cross multiply
1.738 × volume = 16.24
Divide both side by 1.738
Volume of magnesium = 16.24/1.738
Volume of magnesium = 9.34 cm³
Therefore, the density of the magnesium sample is 9.34 cm³.
