Question

What are the different ways to represent compounds? Check all that apply. a structural formula a ball model a space-filling model the Kolbe formula a molecular formula an empirical formula a ball and stick model a cylindric model

Answer 1

Answer:

Compound can be represented as a molecular formula,empirical formula, structural formula,ball and stick model, space filling model.

Explanation:

Compounds can be represented as a chemical formula and a molecular model.

A chemical formula shows the number of atoms present in a compound. Whereas, the molecular model shows the geometry of a compound.

The chemical formula can be further divided into 3 types:

1)molecular formula: indicates the actual number of atoms in a compound.

2)empirical formula: indicates the relative number of atoms present in a compound.

3)structural formula: is illustrated in the forms of lines which actually shows the bond(such as covalent bond) and also shows how atoms are connected to each other in a molecule.

Molecular model is preferably a better way to represent a molecule. It is categorised into the following:

1)a ball and stick model: its a three dimensional representation of a compound. The atom(s) in a compound is represented by ball while, their chemical bonds are shown by sticks.

2)A space filling model: its a three dimensional structure,it represents the size and shape of the whole molecule,showing relatively how much space each atom in a molecule occupies.

Answer 2

Answer:

structural formula, space-filling model, molecular formula, empirical formula and ball and stick model.

Explanation:

Chemical compounds are resultants of chemical elements in a reaction. There are several ways of represent a compound, they are;

Structural formula represents chemical compounds in a two dimensional diagram, showing the bonding of the various elements.

Empirical formula gives the relative number of atoms in the compound, while molecular formula shows the actual number of atoms. Space filling, and ball and stick models are three dimensional diagrams describing the relationship between elements represented as balls and bonds as sticks ( for ball and stick model), and the space occupied by individual elements in the compound (space filling).
