WebElements Periodic Table » Calcium » reactions of …

Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium oxide is more normally made by heating calcium carbonate. Calcium, immediately below magnesium in the periodic table is more reactive with air than magnesium.

What is the reaction of calcium with water? - Quora

Yes calcium reacts with hot water but cold water is preferred over hot water for reacting with calcium because increasing the temperature increases the rate of reaction but calcium is already a reactive metal and using hot water can make the reaction more
