Question

Can someone help me with this question?

Use the reaction to answer the question. Which type of reaction is this?
CuSO4 + Zn → Cu + ZnSO4
A) combustion
B) single-replacement
C) ionic
D) electronegative

Answer 1

The reaction CuSO4 + Zn → Cu + ZnSO4 is a single-replacement reaction, where zinc displaces copper from copper sulfate to form zinc sulfate and elemental copper. The correct answer is option B.

Step-by-step explanation:

The reaction

CuSO4 + Zn → Cu + ZnSO4

is an example of a single-replacement reaction. In this type of reaction, one element trades places with another element that is part of a compound.

In the given reaction, zinc (Zn) displaces copper (Cu) from copper sulfate (CuSO4) to form zinc sulfate (ZnSO4) and elemental copper (Cu). This is because zinc is more reactive than copper and can replace it in the compound.

The general form of a single-replacement reaction is A + BC → AC + B, where element A replaces B in compound BC to form compound AC and release element B.

An additional example provided is the reaction Mg(s) + Cu(NO3)2 (aq) → Mg(NO3)2 (aq) + Cu(s), which further illustrates this metal replacement process.
