Hydrogen bonds are stronger than the dipole dipole attraction force present in any molecule.
<h3>What is bonding in molecules?</h3>
Bonding is a type of attraction force which is present between the different atoms or elements of any substance.
- Dipole dipole attraction force is a weak force as compared to the hydrogen bonding and present between any two oppositely charged atoms.
- Hydrogen bond is present between the hydrogen atom and more electronegative atoms like O, S, N and F.
Hence main difference is that hydrogen bond is only present between the hydrogen atom and more electronegative.

The hydrogen bonds that form between water molecules account for some of the essential and unique properties of water. The attraction created by hydrogen bonds keepswater liquid over a wider range of temperature than is found for any other molecule its size.

The empirical formula for pyrite is FeS2.
HOW TO CALCULATE EMPIRICAL FORMULA:
- The empirical formula represents the simplest whole number ratio of constituents element of a compound. The empirical formula of pyrite can be calculated as follows:
46.5 mass % Fe = 46.5g of Fe
53.5 mass % S = 53.5g of S
- Next, we divide each element's mass value by its molar mass
Fe = 46.5g ÷ 56g/mol = 0.83mol
S = 53.5g ÷ 32g/mol = 1.67mol
- Next, we divide each mole value by the smallest (0.83mol)
Fe = 0.83mol ÷ 0.83 = 1
S = 1.67mol ÷ 0.83 = 2.014
Approximately, the ratio of Fe to S is 1:2. Therefore, the empirical formula of pyrite is FeS2.

A. A diagram showing the effects of temperature and pressure on phase
Explanation:
A phase diagram is a diagram that shows the effects of temperature and pressure on phase.
- A phase diagram shows how different substances are transformed from one form to another.
- The transformation is an interplay between pressure and temperature.
- The phase graph represents physical state changes.
- A phase change is made up of pressure on the y-axis and temperature on the x - axis.
