Question

Скласти рівняння реакції. які є можливими СРОЧНО БУДЬ ЛАСКА Sn+PbCO2= Zn+Bi(NO3)3= Al+MgCl2=

Answer 1

1) не відбувається

2)3 Zn + 2 Bi(NO3)3 → 2 Bi + 3 Zn(NO3)2

3) Al + MgCl2 → Ø
Реакція у нормальних умовах не відбувається,вона повинна бути оборотною
2 Al + 3 MgCl2 ← 2 AlCl3 + 3 Mg

Answer 2

Equations for the Given Reactions:

1. The reaction between tin (Sn) and lead(II) carbonate (PbCO2) can be represented by the following equation:

Sn + PbCO2 → SnCO3 + Pb

This equation shows that tin reacts with lead(II) carbonate to form tin(II) carbonate and lead.

2. The reaction between zinc (Zn) and bismuth(III) nitrate (Bi(NO3)3) can be represented by the following equation:

Zn + Bi(NO3)3 → Zn(NO3)2 + Bi

This equation shows that zinc reacts with bismuth(III) nitrate to form zinc nitrate and bismuth.

3. The reaction between aluminum (Al) and magnesium chloride (MgCl2) can be represented by the following equation:

2Al + 3MgCl2 → 2AlCl3 + 3Mg

This equation shows that aluminum reacts with magnesium chloride to form aluminum chloride and magnesium.

Please note that these equations are balanced and represent the stoichiometry of the reactions.
