Answer:
Displacement reaction is the answer.
Althouɡh it is quite exothermic.
Explanation:
as, calcium displaces some amount of hydrogen from water, thus its a displacement or single displacement reaction
Ca+2H₂O→Ca(OH)₂+H₂↑+∆H
When Calcium oxide reacts with water, its a combination reaction.
CaO+H₂O→Ca(OH)₂+∆H
