NaCl + BeF2 → NaF + BeCl2

Balanced: 2 NaCl + BeF2 → 2 NaF + BeCl2

FeCl3 + Be3(PO4)2 → BeCl2 + FePO4

Balanced: 2 FeCl3 + Be3(PO4)2 → 3 BeCl2 + 2 FePO4

AgNO3 + LIOH → AgOH + LINO3

Balanced: AgNO3 + LIOH → AgOH + LINO3

CH4 + O2 → CO2 + H2O

Balanced: CH4 + 2 O2 → CO2 + 2 H2O

Mg + Mn2O3 → MgO + Mn

Balanced: 4 Mg + Mn2O3 → 4 MgO + 2 Mn

AlBr3 + K → KBr + Al

Balanced: AlBr3 + 3 K → 3 KBr + Al

FeO + PdF2 → FeF₂ + PdO

Balanced: FeO + PdF2 → FeF2 + PdO

P4 + Br2 → PBr3

Balanced: P4 + 6 Br2 → 4 PBr3

LiCl + Br2 → LiBr + Cl2

Balanced: LiCl + Br2 → LiBr + Cl2

PbBr2 + HCI → HBr + PbCl2

Balanced: PbBr2 + 2 HCI → 2 HBr + PbCl2

The chemical equation you provided is:

PbBr ​2 +HCl→ HBr +PbCl 2

To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here's the balanced equation:

PbBr 2 +2HCl→2HBr+PbCl 2

​Explanation:

On the reactant side, there are now two hydrogen atoms on the left (from 2HCl ) to balance the two hydrogen atoms on the right (from 2HBr). The coefficient of PbBr 2remains 1 on both sides.

On the product side, there are now two chlorine atoms on the left (from

PbCl 2 ) to balance the two chlorine atoms on the right (from 2HCl). The coefficient of HBr

HBr also remains 2 on both sides.

This balanced equation ensures that the law of conservation of mass is satisfied, meaning that the number of atoms of each element is the same on both sides of the chemical
