Question

пожалуйста!!!! S=so2=so3=h2so4=baso4

Answer 1

S + O₂ = SO₂ 
2SO₂ + O₂ = 2SO₃
SO₃ + H₂O= H₂SO₄
H₂SO₄ + BaCl₂ = BaSO₄ + 2HCl

Answer 2

S = Sulfur SO2 = Sulfur dioxide SO3 = Sulfur trioxide H2SO4 = Sulfuric acid BaSO4 = Barium sulfate

Sulfur is a chemical element with the symbol S and atomic number 16. Sulfur dioxide (SO2) and sulfur trioxide (SO3) are both compounds of sulfur and oxygen. Sulfur dioxide is a colorless gas with a pungent odor, while sulfur trioxide is a white crystalline solid.

Sulfuric acid (H2SO4) is a highly corrosive strong mineral acid. It is a colorless to slightly yellow liquid that is soluble in water. Sulfuric acid is used in various industrial processes, including as a chemical reagent, in the production of fertilizers, and in the refining of petroleum.

Barium sulfate (BaSO4) is a white crystalline solid that is insoluble in water. It is used medically as a contrast medium for X-ray imaging and as a filler or extender in products such as paints and plastics.

These compounds are all related to sulfur and have different chemical properties and uses.
