Question

Срочно! H2S-K2S-PbS-SO2-SO3-MgSO4

Answer 1

H2S-K2S-PbS-SO2-SO3-MgSO4

H₂S+KOH=K₂S+H₂O

K₂S+Pb(NO₃)₂=PbS↓+2KNO₃

2PbS+3O₂=2SO₂↑+2PbO

2SO₂+O₂=2SO₃

SO₃+MgO=MgSO₄

Answer 2

H2S + KOH = K2S + H2O

K2S + Pb(No3)2 = PbS + KNO3

PbS + O2 = PbO + SO2

SO2 + O2 = SO3

SO3 + Mg(OH)2 = MgSO4 + H2O

Answer 3

H2S, K2S, PbS, SO2, SO3, and MgSO4 are all chemical compounds.

H2S is hydrogen sulfide, a colorless gas with a pungent odor. It is highly toxic and flammable, and is commonly found in natural gas and crude oil. It is also produced by the decomposition of organic matter.

K2S is potassium sulfide, a yellow or red solid that is highly soluble in water. It is used in the production of other chemicals and in the tanning of leather.

PbS is lead sulfide, a dark gray or black solid that is insoluble in water. It is the most important ore of lead and is also used as a semiconductor in electronic devices.

SO2 is sulfur dioxide, a colorless gas with a pungent odor. It is a byproduct of the burning of fossil fuels and is a major contributor to air pollution. It is also used in the production of sulfuric acid.

SO3 is sulfur trioxide, a white solid that is highly reactive with water. It is used in the production of sulfuric acid and other chemicals.

MgSO4 is magnesium sulfate, a white crystalline solid that is highly soluble in water. It is used in the production of fertilizers and as a drying agent in many industrial applications. It is also used as a medical treatment for various conditions.
