Question

Написать молекулярное, повное и скорочено ионно-молекулярное уравнение реакции NiCl2+Na2CO3

Answer 1

Реакция обмена с образованием плохо растворимого вещества (карбоната никеля): 

NiCl₂ + Na₂CO₃ = NiCO₃↓ + 2NaCl

Ni²⁺ + 2Cl⁻ + 2Na⁺ + CO₃²⁻ = NiCO₃ + 2Na⁺ + 2Cl⁻

Ni²⁺ + CO₃²⁻ = NiCO₃

Answer 2

Molecular Equation:

The molecular equation for the reaction between NiCl2 and Na2CO3 is as follows:

NiCl2 + Na2CO3 -> NiCO3 + 2NaCl

Ionic Equation:

The ionic equation for the reaction between NiCl2 and Na2CO3 can be written by dissociating the compounds into their respective ions:

Ni^2+ + 2Cl^- + 2Na^+ + CO3^2- -> NiCO3 + 2Na^+ + 2Cl^-

Net Ionic Equation:

To write the net ionic equation, we eliminate the spectator ions (ions that appear on both sides of the equation and do not participate in the reaction). In this case, the spectator ions are Na^+ and Cl^-.

Net Ionic Equation: Ni^2+ + CO3^2- -> NiCO3

In this net ionic equation, Ni^2+ and CO3^2- ions combine to form NiCO3, which is the only product of the reaction.

Please note that the above equations are based on the information provided and may vary depending on the reaction conditions and the states of the compounds involved.
