Answer:
Chemical formula determines chemical structure and the properties of a substance.
Explanation:
The chemical formula of a substance depicts what atoms are in the substance, how many times they reoccur and in what ratio. Chemical formulas could be in form of: empirical, molecular or structural formula.
All of these determine the property of the substance, for instance in isomers of a compound.
Atoms are the smallest unit of a molecule, which in different numbers, patterns, and compositions make up the chemical formula of the substance.
The number and type of atom present affect the properties of a molecule or substance.
The chemical formula is a representation of a compound, molecule, or s substance in specified numbers and types of atoms.
The chemical formula gives the idea about the ratio of atoms, the repeating units of a particular atom, and the bonds between them.
The chemical formula can be represented in empirical, molecular, or structural formulas.
For example, butane and isobutane are isomers, which have the same chemical formula but different structures. The difference in the structure gives them different physical properties.
Therefore, the number of atoms and type of atoms in a chemical affect their properties.
