Answer 1

ANSWER:-

◆ When Zinc (Zn) react with Copper Sulphate (CuSO4) to give Zinc Sulphate (ZnSO4) and Copper (Cu).

equation = Zn + SO4 ---- ZnSO4 + Cu

◆ It is Displacement Reaction.

◆ Displacement Reaction :- the reaction in which high metal displace the less reactive metal is called Displacement reaction.

◆ In this reaction Zinc is high reactive metal than Copper because Zinc will be displace the copper.

◆ equation = Zn + SO4 ---- ZnSO4 + Cu

● The reactant in the following reaction
answer is B) Zinc and Copper Sulphate.

● The product in the following reaction
answer is C) Zinc Sulphate and Copper

Answer 2

Zn + CuSO4 -----> ZnSO4 + Cu

B. zinc and copper (II) sulfate

The reactants are zinc and copper sulfate. Reactants are substances that are present at the time of the beginning of any chemical reaction. These are present on the left side of the arrow in a chemical equation.

c. zinc sulfate and copper

The products are zinc sulfate and copper. Products are elements or substances that are present at the time of the end of any chemical reaction or new substances produced in the reaction. These are present at the right of the arrow in a chemical equation.

NOTE:

In any chemical reaction, the chemical bonds break between reactants and new chemical bonds forms which result in product molecules.
