Answer from: ayeeitsenaly4175

Answer :

Reaction 1 : Add Zinc to Copper Sulfate.

Observations of Reactants : Zinc is in solid state and copper sulfate in aqueous state.

Predicted Type(s) of Reaction : Single-displacement reaction

Observations of Products : Copper is in solid state and zinc sulfate in aqueous state.

The balanced chemical reaction : $Zn(s)+CuSO_4(aq)\rightarrow Cu(s)+ZnSO_4(aq)$

Types of reaction : Single-displacement reaction : It is a type of reaction in which a single element displaces another element in a compound.

Reaction 2 : Mix Potassium Iodide and Lead (II) Nitrate.

Observations of Reactants : Potassium iodide is in solid state and lead nitrate in aqueous state.

Predicted Type(s) of Reaction : Double-displacement reaction

Observations of Products : Lead iodide is in solid state and potassium nitrate in aqueous state.

The balanced chemical reaction : $2KI(s)+Pb(NO_3)_2(aq)\rightarrow PbI_2(s)+2KNO_3(aq)$

Types of reaction : Double-displacement reaction : It is a type of reaction in which two reactants exchange their ions to form two new compounds.

Reaction 3 : Burn Copper Wire.

Observations of Reactants : Copper is in solid state and oxygen in gas state.

Predicted Type(s) of Reaction : Oxidation reaction

Observations of Products : Copper oxide is in solid state.

The balanced chemical reaction : $2Cu(s)+O_2(g)\rightarrow 2CuO(s)$

Types of reaction : Oxidation reaction : In a oxidation reaction, a substance gains oxygen.

Reaction 4 : Heat Sodium Carbonate.

Observations of Reactants : Sodium carbonate is in solid state.

Predicted Type(s) of Reaction : Thermal decomposition reaction

Observations of Products : Sodium oxide is in solid state and carbon dioxide in gas state.

The balanced chemical reaction : $Na_2CO_3(s)\overset{\Delta}\rightarrow Na_2O(s)+CO_2(g)$

Types of reaction : Thermal decomposition reaction : It is defined as the breaking down of a chemical compound due to heating.
