Compounds can be exemplified in two main ways. These are Chemical Formula and Molecular Model.

Chemical formula includes:

Structural formula – this is a formula that shows the arrangement of atoms in the molecule of a compound.

Molecular formula – this is a formula giving the number of atoms of each elements to present in one molecule of a specific compound.

Empirical formula – this is a formula giving the proportions of elements present in a compound.

Molecular model:

Space-filling model - represents atoms fill the space between each other.

Ball and stick model - represents atoms as balls and chemical bonds as sticks.

Remember that a compound is a substance that is formed when two or more elements are bonded together.

The different ways to represent compounds:

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

Further explanation

The empirical formula (EF) is the smallest atomic ratio of the constituent elements.

The empirical formula shows the simplest comparison of the molecules making up the molecule

The Molecular formula (MF) is a formula that shows the number of atomic elements that make up a compound.

$\large{\boxed{\bold{(EF)n=MF}}}$

The empirical formula can be identical to the molecular formula. Ion compounds only have an empirical formula and do not have a molecular formula because ion compounds are formed from positive ions and negative ions, not from molecules.

Structural formulas are depictions of bonds between atoms in a molecule. The structural formula is obtained from the Lewis formula by replacing each pair of electrons with a line. From this structural formula, you can see a single bond or a double bond

A ball-and-stick model describes an atom as a ball and its bond as a stick

A space-filling molecular model describes molecules like a ball-and-stick model but without the stick

Whereas the Kolbe formula, a ball model, and a cylindric model are unknown

1. suppose a reaction mixture, when diluted with water, afforded 300 ml of an aqueous solution of 30 g of the reaction product malononitrile [ch2(cn)2], which is to be isolated by extraction with ether. the solubility of malononitrile in ether at room temperature is 20.0 g/100 ml, and in water is 13.3 g/100 ml. what weight of malononitrile would be recovered by extraction with (a) three 100-ml portions of ether and (b) one 300-ml portion of ether? suggestion: for each extraction, let x equal the weight extracted into the ether layer. in part (a), the concentration in the ether layer is x/100 and in the water layer is (30 x)/300; the ratio of these quantities is equal to k 20/13.3.

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
