A yellow solid X was heated in a lab. Which can only dissolve in Carbon (IV) Sulphide (CS2) when it was heated until 100°C it formed Y. The next day it found to have formed Z.
1)Name X,Y and Z
2) Differentiate between Y and Z.
1)
X: Sulfur
Y: Sulfur vapor
Z: Sulfur dioxide
2)
Y is sulfur vapor, which is the gaseous form of sulfur. It is formed when solid sulfur (X) is heated at 100°C and undergoes sublimation, directly changing from a solid to a gas phase without passing through the liquid phase.
Z is sulfur dioxide, a chemical compound formed when sulfur vapor (Y) reacts with oxygen in the air. This reaction occurs over time, so when the lab checked the next day, they found that sulfur vapor had reacted with oxygen to form sulfur dioxide (Z).
1)
- X: The yellow solid is an organic compound called Sulfur.
- Y: When Sulfur (X) is heated in the presence of Carbon (IV) Sulphide (CS2) until 100°C, it forms a yellow liquid called Sulfur (S8, octasulfur).
- Z: The next day, Sulfur (S8) undergoes a polymerization reaction and forms a solid called Plastic Sulfur or Polymeric Sulfur.
2) Differentiation between Y and Z:
- Y (Sulfur S8): This is a yellow liquid formed when Sulfur is heated with Carbon (IV) Sulphide until 100°C. It consists of octasulfur molecules (S8 rings), which are held together by weak intermolecular forces. It has a relatively low molecular weight and is still soluble in CS2.
- Z (Polymeric Sulfur): This is a solid form of sulfur formed through the polymerization of Sulfur (S8). The S8 molecules undergo a chemical reaction, resulting in the formation of long chains or networks of sulfur atoms. Polymeric Sulfur has a higher molecular weight and is insoluble in CS2. It exhibits different physical and chemical properties compared to liquid Sulfur (S8), such as increased stability and higher melting point.
To answer your questions, we will need more information about the properties and characteristics of the substances involved, as well as the reactions that took place. However, I can explain the general approach for finding the answers to your questions.
1) Name X, Y, and Z:
To determine the names of the substances, we need to consider the information given. The initial substance, X, is described as a yellow solid, but no specific details are provided. It would be helpful to know any other observable properties or additional information about X.
Regarding Y, it is stated that X dissolves in Carbon (IV) Sulphide (CS2) when heated until 100°C, resulting in the formation of Y. Without more information, it is difficult to identify the exact compound formed or its name. Additional details, such as the composition or any unique properties of Y, would be necessary for a more precise identification.
As for Z, it is mentioned that it was formed the next day. However, there is no information given about the nature or properties of Z. Therefore, without further details, it is not possible to determine its name.
2) Differentiating between Y and Z:
Unfortunately, without any details provided about the properties, composition, or reactions involving Y and Z, it is impossible to differentiate them. More information is needed to compare and contrast the two compounds.
To accurately identify and differentiate Y and Z, it would be helpful to know any chemical reactions, physical characteristics, or any tests conducted on these substances. These details would enable us to understand their distinct properties and differences.
In summary, to answer your questions, we would need additional information about the substances X, Y, and Z, such as their specific properties, reactions, or any other identifiable characteristics.
