We have that the the density of FeS is mathematically given as
From the question we are told
Iron(II) sulfide has a primitive <em>cubic</em> unit cell with <em>sulfide</em> ions at the <em>lattice points.</em>
The ionic radii of iron(II) ions and sulfide ions are 88 pm and 184 pm, respectively.
What is the density of FeS (in g/cm3)?

Answer:
liquid, solid, and gas
Explanation: It depends where the molecules are moving. When a solid the molecules are vibrating and are all together, compact, the molecules are also very slow. When a liquid the molecules are moving back and forth, up and down, and are less compact, but moving faster. When a gas, the molecules move everywhere very quickly, moving super fast.
Answer:
Distance between the carbon atom = 491 pm
Explanation:
Given:
1 pm = 1 × 10⁻¹² m
Distance between the carbon atom = 2.81 × 10⁻⁸ cm
Find:
Distance in picometers
Computation:
Distance between the carbon atom = 2.81 × 10⁻⁸ cm = 491 X 10⁻¹² m
Distance between the carbon atom = 491 pm
When temperature increases, there is more energy in a substance. For example, when water boils, more energy is produced. The arrangement of molecules in a solid are closer together and more packed, while the arrangement of molecules in a liquid are father apart and less packed.
