Answer:
That's not true. It would in fact be physical.
Explanation:
physical change: some of its physical properties may change but its identity does not
They have a low boiling point because of weak intermolecular forces. They
Explanation:
Covalent compounds are compounds that are known to have weak intermolecular forces and hence low boiling point.
Covalent bonds are bond formed between two or more atoms having zero or very small electronegativity difference. Such bonds exists between molecules of non-metals.
Here are some properties of covalent bonds;
- They are gases or volatile liquids or low melting point solids
- Most of them are insoluble in polar solvents or water but they are generally soluble in non-polar organic solvents.
- They are mainly non-conductors.

1 mole ------------ 6.02x10²³ atoms
? moles ----------- 3.01x10²³ atoms
moles = ( 3.01x10²³ ) x 1 / 6.02x10²³
=> 0.5 moles Mg

The Density of the metal is 5.6 g/cm³
<h3>What is the density of a substance?</h3>
The density of a substance is the ratio of the mass and the volume of the substance.
The density of the metal is calculated as follows:
mass of metal = 1.4 kg = 1400 g
volume of metal = 3.2 * 17.1 * 4.6 = 251.712 cm³
Density of metal = 1400 g/251.712 cm³
Density of the metal = 5.6 g/cm³
Therefore, the density of the metal is obtained from the mass and the volume of the metal.
