B) a molecule
A molecule is formed when two atoms join together with a covalent bond.
Answer:
8g/mL
Explanation:
Density = Mass/Volume
There is 5.6g of Iron added to the water of 23.60mL and it rose by 0.7mL.
Density = 5.6g/0.7mL of Iron.
Answer:Van der Waals forces are responsible for certain cases of pressure broadening (van der Waals broadening) of spectral lines and the formation of van der Waals molecules. ... The main characteristics of van der Waals forces are: They are weaker than normal covalent and ionic bonds.

Answer:
Light is made up of wavelengths of light, and each wavelength is a particular colour. The colour we see is a result of which wavelengths are reflected back to our eyes. The visible spectrum showing the wavelengths of each of the component colours. The spectrum ranges from dark red at 700 nm to violet at 400 nm.The 'colour' of an object is the wavelengths of light that it reflects. This is determined by the arrangement of electrons in the atoms of that substance that will absorb and re-emit photons of particular energies according to complicated quantum laws.The reason that different waves of light appear to be different colors of light is because the color of a light wave depends on its wavelength. For example, the wavelength of blue light is about 450 nanometers, while the wavelength of red light is about 700 nanometers.
