Question

Classify each of these reactions. A single reaction may fit more than one classification Cao+CO,>CaCO, combination (synthesis) decomposition displacement double-displacement (a.k.a. exchange or metathesis) redox combination (synthesis) decomposition displacement double (a.k.a. exchange or metathesis) redox NaNO, +HCINaCI+HNO, combination (synthesis) decomposition displacement double (ak.a. exchange or metathesis) redox combination (synthesis) displacement doub (a.k.a. exchange or metathesis) redox lacement

Explanation / Answer

Ba(ClO3)2 —>BaCl2 + O2

This is decomposition reaction as one reactant is decomposing to give more than 1 product

This is redox reaction as Cl is reduced and O is oxidised

CaO + CO2 —> CO3

This is combination reaction as more that one reactant combine to form one producct

NaNO2 + HCl —> NaCl + HNO22

This is double displacement reaction as both the anions are replaced by new cation

ZnSO4 + Mg —> Zn + MgSO4

This is displacement reaction as only 1 anion is replaced

This is redox reaction as Zn is reduced and Mg is oxidised

So, the correct answer for this is displacement and redox
