Sulfur dioxide, at room temperature is a gas, so, I guess it is "softer". Silicon Dioxide is a solid at room temperature, and is 8 (very hard)on the Moh's hardness scale. If powdered, though, it "feels" soft. But it still will scratch many substances--plastics, marble, etc. It makes a good polishing compound.
The chemical compound name for SO2 is sulfur dioxide.
Sulfur dioxide
Sulfur dioxide.
The balanced chemical equation for the reaction between silicon and carbon dioxide to form silicon carbide and silicon dioxide is: 3Si + 3CO2 -> SiC + 2SiO2
Burning sulfur in oxygen produces sulfur dioxide.
Quartz is the compound silicon dioxide (SiO2) and contains atoms of silicon and oxygen. It is usually clear. Sulfur is a simple element composed of sulfur atoms. It is opaque and yellow.
The chemical compound name for SO2 is sulfur dioxide.

Sulfur dioxide.
The balanced chemical equation for the reaction between silicon and carbon dioxide to form silicon carbide and silicon dioxide is: 3Si + 3CO2 -> SiC + 2SiO2
Burning sulfur in oxygen produces sulfur dioxide.
Silicon dioxide is a compound, not an atom. It is composed of one silicon atom and two oxygen atoms bonded together. Each of the atoms in silicon dioxide retains its individual identity within the compound.
Sulfur dioxide (SO2) consists of one sulfur atom and two oxygen atoms. The percentage of sulfur in sulfur dioxide is calculated as the mass of sulfur divided by the total mass of the compound, which is 32.07 grams per mole for sulfur and 64.07 grams per mole for sulfur dioxide. This means that sulfur represents 50% of the total mass of sulfur dioxide.
