Identify the type of reactions in each of the following reactions:
$(i)$ $Zn + H_{2}SO_{4} \longrightarrow ZnSO_{4} + H_{2}$
$(ii)$ $CaO + H_{2}O \longrightarrow Ca(OH)_{2}$
$(i)$ $Zn + H_{2}SO_{4} \longrightarrow ZnSO_{4} + H_{2}$
$(ii)$ $CaO + H_{2}O \longrightarrow Ca(OH)_{2}$
(N/A) $(i)$ This is a displacement reaction because zinc $(Zn)$ displaces hydrogen $(H_{2})$ from sulfuric acid $(H_{2}SO_{4})$.
$(ii)$ This is a combination reaction because calcium oxide $(CaO)$ and water $(H_{2}O)$ combine to form a single product,calcium hydroxide $(Ca(OH)_{2})$.
$(ii)$ This is a combination reaction because calcium oxide $(CaO)$ and water $(H_{2}O)$ combine to form a single product,calcium hydroxide $(Ca(OH)_{2})$.
