Question

Sulfur exists in two polymorphic forms ____________ and _____________.

a) rhombic and monoclinic

b) rhombic and triclinic

c) hexagonal and triclinic

d) hexagonal and monoclinic​

Answer 1

Step-by-step explanation:

Sulfur exists in two polymorphic forms: [A. rhombic and monoclinic.]Rhombic sulfur is the most common form and it is stable at temperatures below 95.4 degrees Celsius. It has a yellow color and forms needle-like crystals. Rhombic sulfur is the form of sulfur that is commonly found in nature, such as in volcanic areas or near hot springs.Monoclinic sulfur, on the other hand, is the less stable form and it is stable at temperatures above 95.4 degrees Celsius. It has a different crystal structure compared to rhombic sulfur, with longer and more needle-like crystals. Monoclinic sulfur is formed when rhombic sulfur is heated above its melting point and then cooled slowly.These two forms of sulfur have different physical properties and structures due to the arrangement of the sulfur atoms in their crystal lattices. Understanding the different polymorphic forms of sulfur is important in various fields, including chemistry, materials science, and geology.

Answer 2

Sulfur exists in two polymorphic forms: [A. rhombic and monoclinic.]

Rhombic sulfur is the most common form and it is stable at temperatures below 95.4 degrees Celsius. It has a yellow color and forms needle-like crystals. Rhombic sulfur is the form of sulfur that is commonly found in nature, such as in volcanic areas or near hot springs.

Monoclinic sulfur, on the other hand, is the less stable form and it is stable at temperatures above 95.4 degrees Celsius. It has a different crystal structure compared to rhombic sulfur, with longer and more needle-like crystals. Monoclinic sulfur is formed when rhombic sulfur is heated above its melting point and then cooled slowly.

These two forms of sulfur have different physical properties and structures due to the arrangement of the sulfur atoms in their crystal lattices. Understanding the different polymorphic forms of sulfur is important in various fields, including chemistry, materials science, and geology.
