Zinc + Silver nitrate —> Zinc nitrate + Silver
Zn + AgNO3 → Ag + Zn(NO3)2 : Put a "2" in front of the AgNO3 to balance the NO3 (nitrate). Balance the Ag on the product side.
=> Zn + 2AgNO3 = 2Ag + Zn(NO3)2
Aluminium + Copper chloride => Aluminium chloride + Copper
AI + CuCI2 => AICI3 + Cu : Put a coefficient of two in front of the AlCl3. Change the coefficient in front of CuCl2 to balance the chlorine atoms.
=> 2Al + 3CuCl2 = 2AlCl3 + 3Cu
Barium chloride + Potassium sulphate => Barium sulphate + Potassium chloride
BaCl2 + K2 SO4 => BaSO4 + KCl : Change the coefficient in front of the KCl to balance the equation. Put a "2" in front of the KCl on the product side of the equation.
=> BaCl2 + K2 SO4 = BaSO4 + 2KCl
Potassium bromide (aq) + Barium Iodide (aq) => Potassium Iodide (aq) + Barium bromide (s)
2KBr(aq)+ BaI2(aq)→ 2KI(aq )+ BaBr2(s)
It is a double diaplacement reaction. A double displacement reaction is a type of reaction in which two reactants exchange ions to form two new compounds.
Zinc carbonate (s) => Zinc oxide (s) + Carbon dioxide (g)
ZnCO3 (s) => ZnO (s) + CO2 (g)
It is a decomposition reaction. A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances.
Hydrogen (g) + Chlorine (g) => Hydrogen Chloride (g)
H2 (g) + Cl2 (g) => 2HCl (g)
It is a combination reaction. A combination reaction is a reaction where two or more elements or compounds combine to form a single compound (product).
