Question

Note the type of reaction you expect for the reactants Zn and CuSO4?

Single replacement

Double replacement

Combustion (and synthesis)

synthesis

Decomposition

Answer 1

Answer: Option (a) is the correct answer.

Step-by-step explanation:

A single replacement reaction is defined as the reaction in which a single element displaces another element from a compound.

For example,
`Zn + CuSO_(4) \rightarrow ZnSO_(4) + Cu`

Only a more reactive element can replaces another element from a compound.

So, according to reactivity series zinc element is more reactive than copper. Hence, zinc is able to displace copper in a copper sulfate solution.

Thus, we can conclude that the type of reaction you expect for the reactants Zn and
`CuSO_4` is single replacement.

Answer 2

Single replacement .

Step-by-step explanation:

• Single replacement is a reaction in which one element reacts with another compound to form another compound and another element.

• The reaction between Zn and CuSO₄ represented as:

Zn + CuSO₄ → Cu + ZnSO₄.

Zn replaces Cu from its salt resulting Cu and ZnSO₄.
