Burning of sulfur (or anything else) is a chemical change, not a physical change.
It is a chemical change, an oxidation reaction.
Burning sulfur, or burning anything, is a chemical change.
Burning sulfur, or burning anything, is a chemical change.
Burning sulfur, or burning anything, is a chemical change.
yes
When heating sulfur, a chemical reaction occurs. Sulfur undergoes a phase change from solid to liquid to gas as it is heated, but this is still considered a chemical change because the molecular structure of the sulfur is altered in the process.
Crushing a lump of roll sulfur is a physical change, as the chemical composition of the sulfur remains the same. The process only alters the physical state of the sulfur without changing its chemical properties.
Sulfur burning is a chemical change because it involves a chemical reaction that results in the formation of new substances. When sulfur burns, it combines with oxygen in the air to form sulfur dioxide, which is a different chemical compound with different properties than sulfur alone.
No, this is a chemical change.
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Crushing a lump of sulfur would be considered a physical change because the chemical composition of sulfur remains the same before and after crushing. No new substances are formed during the process.
