Explanation:

I had gotten a 100% on this lab report . EDG21

Answer :

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 :

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

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 :

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

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 :

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

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 :

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