The specific gravity of sulfur dioxide is 2.24 so it is more than twice as dense as air.
Carbon Dioxide is less denser than air.
Carbon dioxide is more dense than air.
It makes Sulphur Dioxide. and little Sulphur Trioxide.
Carbon dioxide is approximately 50 percent heavier than air
Sulfur dioxide is produced when sulfur or compounds containing sulfur, such as sulfur-containing minerals, are heated in the presence of oxygen (air). This can occur during the combustion of fossil fuels, volcanic eruptions, or burning of sulfur-containing materials.
When sulfur burns in air, it forms sulfur dioxide gas (SO2). Sulfur dioxide is a colorless gas with a pungent smell and is a major air pollutant. It can react with moisture in the air to form sulfuric acid, contributing to acid rain.
Burning sulfur in oxygen produces sulfur dioxide.
The concentration of sulfur dioxide in the air can vary depending on location, time, and source of emissions. Generally, levels of sulfur dioxide in the air are measured in parts per billion (ppb) or micrograms per cubic meter (µg/m3). Regulatory agencies set limits for acceptable levels of sulfur dioxide in the air to protect human health and the environment.
"oxidation"
You will get SO2 or sulphur dioxide, an acidic oxide
Volcanoes often emit a harmful gas called sulfur dioxide. Sulfur dioxide is an air pollutant. It causes acid rain.
The specific gravity of Sulfur Dioxide (SO2) compared to air is 2.264. This means that sulfur dioxide weighs 2.264 times as much as air at the same conditions of pressure, temperature and gravitational attraction.
