Question

S8 empirical formula​

Answer 1

Answer with Explanation:

Statistical Formula $S_8$

• There are several allotropic forms of sulphur, each with a different molecular formula. The usual sulphide molecular formula is S8.
• It is best to use the molecular formula when discussing chemical reactions if we know which allotropic form of sulphur is involved in the reaction.
• However, the specific allotropic form of the reactant has no bearing on the chemical equation for some generalised reactions. For instance, when oxygen and sulphur are mixed, sulphur dioxide is created.

$S + O_2 - > SO_2$ the equation is balanced, but

$S_8 + 8O_2 - > 8 SO_2$ is a balanced equation as well

• Chemical elements frequently lack molecular formulas because, like sulphur, they are composed of lone atoms that are not linked by covalent or ionic bonds. Therefore, despite how straightforward the question initially appears, it is not.
• Because only a few number of elements actually exist as molecules at certain temperatures and pressures.
