Question

Запишите молекулярное, полное ионной и сокращенное ионной уравнения: FeS+ HBr→ MgSO4+ K2CO3→ СРОЧНО!!!

Answer 1

Ответ:

Объяснение:

FeS + 2HBr = FeBr₂ + H₂S↑

FeS + 2H⁺ + 2Br⁻ = Fe²⁺ + 2Br⁻ + H₂S↑

FeS + 2H⁺ = Fe²⁺ + H₂S↑

MgSO₄ + K₂CO₃ = MgCO₃↓ + K₂SO₄

Mg²⁺ + SO₄²⁻ + 2K⁺ + CO₃²⁻ = MgCO₃↓ + 2K⁺ + SO₄²⁻

Mg²⁺ + CO₃²⁻ = MgCO₃↓

Answer 2

Molecular Equation:

The molecular equation for the reaction between FeS and HBr is:

FeS + 2HBr → FeBr2 + H2S

Complete Ionic Equation:

To write the complete ionic equation, we need to break down all the reactants and products into their respective ions. The complete ionic equation for the reaction between FeS and HBr is:

Fe2+(aq) + S2-(aq) + 2H+(aq) + 2Br-(aq) → Fe2+(aq) + 2Br-(aq) + H2S(g)

Net Ionic Equation:

The net ionic equation is obtained by removing the spectator ions from the complete ionic equation. In this case, the Fe2+ and Br- ions are spectator ions. The net ionic equation for the reaction between FeS and HBr is:

S2-(aq) + 2H+(aq) → H2S(g)

Ionic Equation for MgSO4 and K2CO3:

The molecular equation for the reaction between MgSO4 and K2CO3 is:

MgSO4 + K2CO3 → MgCO3 + K2SO4

The complete ionic equation for the reaction between MgSO4 and K2CO3 is:

Mg2+(aq) + SO4^2-(aq) + 2K+(aq) + CO3^2-(aq) → MgCO3(s) + 2K+(aq) + SO4^2-(aq)

The net ionic equation for the reaction between MgSO4 and K2CO3 is:

CO3^2-(aq) + Mg2+(aq) → MgCO3(s)

Please note that the states of the reactants and products (aq for aqueous, s for solid, g for gas) are not explicitly mentioned in the given equation. The states are assumed based on the typical properties of the compounds involved.
