Question
Classify each of these reactions. Ba(ClO_3)_2 rightarrow BaCl_2 + 3O_2 combination (synthesis) decomposition displacement (single replacement) exchange (double replacement) NaNO_2 + HCI rightarrow NaCl + HNO_2 combination (synthesis) decomposition displacement (single replacement|) exchange (double replacement) CaO + CO_2 rightarrow CaCO_3 combination (synthesis) decomposition displacement (single replacement) exchange (double replacement) ZnSO_4 + Mg rightarrow Zn + MgSO_4 combination (synthesis) decomposition displacement (single replacement) exchange (double replacement)Explanation / Answer
1. Ba(ClO3)2 ----------> BaCl2 + 3O2
it is decomposition reaction
2. CaO + CO2 ---------> CaCO3
it is a combination reaction
3. NaNO2 + HCl -------> NaCl + HNO2
it is a Exchange (double displacement)
4. ZnSO4 + Mg -----------> Zn + MgSO4
it is displacement (single replacement)
