Write balanced chemical reaction. Write the type of the reaction​

Answer 1

Answer:

(i) When zinc is added to the solution of iron sulphate, the colour of iron sulphate solution changes. It is because zinc is more reactive than iron, therefore, it displaces iron from its solution of iron sulphate and a grey precipitate of iron and a colourless solution of zinc sulphate is formed.

• To be useful, chemical equations must always be balanced. Balanced chemical equations have the same number and type of each atom on both sides of the equation. The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions

Answer 2

Answer:

Zn + FeSO4 ------------> ZnSO4 + Fe

Explanation:

High reactive metal displaces low reactive metal.

It is displacement reaction
