Vera_Pavlovna [14]

Fisher projection is the representation of organic molecule in2-D without destroying the3-D stereochemical information.

<h3>What does a Fischer projection in organic chemistry mean?</h3>

A Fischer projection is a drawing technique used in organic chemistry to depict molecules in two dimensions while maintaining the three-dimensional stereochemical information regarding the absolute arrangement at chiral centers.

<h3>What sets the Fischer projection apart from the Haworth projection?</h3>

In contrast to Fischer projections, which are used to represent sugars in their open-chain form, Haworth projections are typically employed to represent sugars in their cyclic forms.

A chemist can determine the mass of K in a sample of known mass that consists of either pure K2O or pure K2O2. From this informa
Arte-miy333 [17]

Yes , the chemist can answer if the compound in K2O or K2O2

The chemical formula and composition of both the compounds is entirely different. The compound K2O2 has an additional molecule of oxygen than K2O and hence will have have higher molecular mass.

In the compound K2O

molecular mass= 2x 39+16 =94

mass ratio of K in compound= 78/94 = 0.830

In the compound K2O2

molecular mass= 2x 39+16X2 =110

mass ratio of K in compound= 78/110 = 0.710

and hence by the required ratio while extracting K , the chemist may know if the compound is K20 or K2O2

If the ratio is anything different from 0.830 and 0.710 then the compund will be something different
