Go grab your periodic chart and you will see that both oxygen and sulfur are in the same group (column). Elements in the same group have similar chemical properties.
Oxygen is a colorless, odorless gas that is essential for sustaining life on Earth, while sulfur is a yellow solid that has a distinct odor. Oxygen is more abundant in the Earth's atmosphere compared to sulfur. Chemically, oxygen tends to form oxides, while sulfur forms sulfides and sulfates.
Sulfur dioxide (SO2) is a compound that contains sulfur and oxygen. It is formed by the burning of sulfur or other sulfur-containing compounds, and is a common air pollutant.
Sulfur oxide is primarily caused by the burning of fossil fuels containing sulfur, such as coal and oil, in industrial processes and power generation. Incomplete combustion of these fuels leads to the release of sulfur dioxide (SO2) and sulfur trioxide (SO3) into the atmosphere.
Selenium is chemically similar to sulfur as it belongs to the same group in the periodic table (group 16). Both elements have similar chemical properties and can exhibit analogous oxidation states in chemical reactions.
They're all nonmetals.
Calcium sulfate is a compound. It is composed of the elements calcium, sulfur, and oxygen chemically bonded together.
It can be, as long as no other substances are present.
When you heat sulphar you chemically mix it with oxygen therefore creating sulphide
Sulfate ion (SO4^2-) is a common ion formed by sulfur. It is created when sulfur atoms combine with oxygen atoms and gain a -2 charge to achieve stability.
Copper sulfate is a compound, not a mixture. It is composed of copper, sulfur, and oxygen elements chemically bonded in a fixed ratio.
Carbon, hydrogen, sulfur, and oxygen can combine to form a variety of compounds. One common example is thioalcohols, which are molecules containing carbon, hydrogen, sulfur, and oxygen atoms. These compounds can have various applications in organic chemistry and biochemistry.
Sulfur reacts with oxygen to form sulfur dioxide (SO2) or sulfur trioxide (SO3), depending on the conditions. These reactions are exothermic and release energy in the form of heat. Sulfur dioxide is a common byproduct of burning sulfur-containing compounds.
