Water from springs contain dissolved __________ compounds which are used to cure some skin diseases.

Nitric
Carbon
Oxide
Sulphur

The correct answer is: Sulphur.

Sulphur is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under standard conditions, it is a pale yellow, odorless, tasteless, non-toxic, and highly flammable solid. Elemental sulphur occurs naturally in many oxidation states, as pure ore minerals, and in various minerals. In nature, sulphur is found as the mineral sulfur, which is a yellow, odorless, tasteless, non-toxic, and highly flammable solid. Sulfur is also found in the form of sulfides, sulfates, and sulfites. Sulfur is an essential element for life, and it is found in proteins, vitamins, and other compounds. Sulfur is also used in the production of sulfuric acid, which is a major industrial chemical.

Nitric acid is a highly corrosive, strong mineral acid with the molecular formula HNO3. It is a colorless liquid that is miscible with water and has a characteristic sharp odor. Nitric acid is a powerful oxidizing agent and is used in a variety of industrial processes, including the production of fertilizers, explosives, and pharmaceuticals.

Carbon is a chemical element with the symbol C and atomic number 6. It is a non-metallic element that is present in the Earth’s crust in the form of carbon dioxide (CO2) and carbonates. Carbon is also found in organic compounds, such as carbohydrates, proteins, and lipids. Carbon is the basis of life on Earth, and it is essential for the formation of organic compounds.

Oxide is a chemical compound that contains oxygen in its chemical formula. Oxides can be formed by the reaction of oxygen with other elements, or by the decomposition of other compounds. Oxides are often used as pigments, and they can also be used as catalysts.

The answer to the question is: Sulphur.
