Question

Classify the chemical reactions based on the given equations.

A) Single Replacement
B) Double Replacement
C) Synthesis
D) Decomposition

2KCl + 2KCl → 2KCl2
Cu(SO4)2 + 2Zn → 2ZnSO4 + Cu
HC2H302 → 2CO2 + 2H2O
Pb(NO3)2 + 2KI → PbI2 + 2KNO3
zinc + sulfuric acid → hydrogen gas + zinc sulfate
magnesium chloride + potassium oxalate → magnesium oxalate + potassium chloride

Answer 1

The given chemical reactions can be classified as single replacement, double replacement, synthesis, and decomposition reactions.

Step-by-step explanation:

The given chemical reactions can be classified as follows:

A) Single Replacement: zinc + sulfuric acid → hydrogen gas + zinc sulfate

B) Double Replacement: magnesium chloride + potassium oxalate → magnesium oxalate + potassium chloride

C) Synthesis: 2KCl + 2KCl → 2KCl2

D) Decomposition: Cu(SO4)2 + 2Zn → 2ZnSO4 + Cu
